The XML class can be used to both parse and create XML documents.

Syntax

class ipworks.XML

Remarks

The XML class can operate as either a parser or writer of XML.

Parsing XML

The XML class parses XML documents and verifies that they are well-formed. The results are provided through a set of events complying with the SAX2 specification.

In addition, the document structure may be queried through an xpath mechanism that supports a subset of the XPath specification.

The parser is optimized for read applications, with a very fast engine that builds internal DOM structures with close to zero heap allocations. Additionally, build_dom can be set to False which reduces the overhead of creating the DOM and offers a fast forward-only parsing implementation which fires events to provide the parsed data.

When parsing a document events will fire to provide information about the parsed data. After parse returns the document may be navigated by setting xpath if build_dom is True (default). If build_dom is False parsed data is only accessible through the events.

Events are fired only when qualifying conditions (such as, for example, the beginning of a new element) are met. In the meantime, text will be buffered internally. The following events will fire during parsing:

If build_dom is True (default), xpath may be set after this method returns. xpath implements a subset of the XML XPath specification, allowing you to point to specific elements in the XML documents.

The path is a series of one or more element accessors separated by '/'. The path can be absolute (starting with '/') or relative to the current xpath location.

The following are possible values for an element accessor:

'name'A particular element name
name[i]The i-th subelement of the current element with the given name
[i]The i-th subelement of the current element
[last()]The last subelement of the current element
[last()-i]The subelement located at the last location minus i in the current element
name[@attrname="attrvalue"]The subelement containing a particular value for a given attribute (supports single AND double quotes)
..The parent of the current element
When xpath is set to a valid path, x_element points to the name of the element, with x_parent, x_namespace, x_prefix, x_child_name, x_child_namespace, x_child_prefix, x_child_x_text, and x_text providing other properties of the element. The attributes of the current element are provided in the attr_name, attr_namespace, attr_prefix, and attr_value properties.

build_dom must be set to True prior to parsing the document for the xpath functionality to be available.

Example (Setting XPath):

Document rootXML.XPath = "/"
Specific ElementXML.XPath = "/root/SubElement1/SubElement2/"
i-th ChildXML.XPath = "/root/SubElement1[i]"

Input Properties

The class will determine the source of the input based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found, the search stops.

If parsing multiple documents call reset between documents to reset the parser.

An additional "relaxed" mode allows for lexical parsing of non-XML documents (e.g. HTML). This is enabled by setting validate to False. In this case, events will be fired as elements, entities, etc. are encountered, but the structure of the document will not be checked for "well-formedness", and the internal DOM structure will not be built.

Writing XML

To use the class first decide whether or not to write to file, or to output_data.

Output Properties

The class will determine the destination of the output based on which properties are set.

The order in which the output properties are checked is as follows:

To begin writing the XML document first optionally set xml_declaration. If this is not set the class will use a default XML declaration at the beginning of the document.

Next begin adding elements to your document. Calling start_element will open an element with the specified name. To create a nested structure continue calling start_element to open more child elements. To write a value within an element call put_string. To close the element that was last opened call end_element. Each time end_element is called the element at the current level is closed. Alternatively, calling put_element will write the element specified with the value specified and will also close the element.

To write an attribute of the current element, after calling start_element call put_attr. Call put_attr multiple times to add multiple attributes.

Writing comments or CDATA can be done at any time with the put_comment and put_c_data methods.

To close your XML document call save. You can call save from any location and it will close any remaining open elements automatically.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

end_element Method

Writes the closing tag of an open XML element.

Syntax

def end_element() -> None: ...

Remarks

Writes the closing tag of the XML element most recently opened using start_element.

If no elements are opened, the call fails with an error

flush Method

Flushes the parser and checks its end state.

Syntax

def flush() -> None: ...

Remarks

When flush is called, the parser flushes all its buffers, firing events as necessary, and then checks its end state. If validate is true, the parser verifies that all open elements were closed, returning an error if not.

get_attr Method

Returns the value of the specified attribute.

Syntax

def get_attr(attr_name: str) -> str: ...

Remarks

This method returns the value of the attribute specified by the AttrName parameter.

If the attribute does not exist an empty string is returned. The behavior when an attribute does not exit is controlled by ErrorOnEmptyAttr.

Please refer to the attr_name, attr_namespace, attr_prefix, and attr_value properties for more information.

has_xpath Method

Determines whether a specific element exists in the document.

Syntax

def has_xpath(xpath: str) -> bool: ...

Remarks

This method determines whether a particular XPath exists within the document. This may be used to check if a path exists before setting it via xpath.

This method returns True if the xpath exists, False if not.

See xpath for details on the XPath syntax.

load_dom Method

Loads the DOM from a file.

Syntax

def load_dom(file_name: str) -> None: ...

Remarks

The load_dom method loads a DOM structure previously saved by save_dom from the file specified in FileName.

Please refer to the save_dom method for more information.

load_schema Method

Load the XML schema.

Syntax

def load_schema(schema: str) -> None: ...

Remarks

This functionality is not yet implemented.

This method loads the schema specified in the Schema parameter. The Schema may be specified as either a string or the path to a file on disk.

The class will validate the input data during parsing to verify it adheres to the schema.

parse Method

This method parses the specified XML data.

Syntax

def parse() -> None: ...

Remarks

This method parses the specified XML data.

When parsing a document events will fire to provide information about the parsed data. After parse returns the document may be navigated by setting xpath if build_dom is True (default). If build_dom is False parsed data is only accessible through the events.

Events are fired only when qualifying conditions (such as, for example, the beginning of a new element) are met. In the meantime, text will be buffered internally. The following events will fire during parsing:

If build_dom is True (default), xpath may be set after this method returns. xpath implements a subset of the XML XPath specification, allowing you to point to specific elements in the XML documents.

The path is a series of one or more element accessors separated by '/'. The path can be absolute (starting with '/') or relative to the current xpath location.

The following are possible values for an element accessor:

'name'A particular element name
name[i]The i-th subelement of the current element with the given name
[i]The i-th subelement of the current element
[last()]The last subelement of the current element
[last()-i]The subelement located at the last location minus i in the current element
name[@attrname="attrvalue"]The subelement containing a particular value for a given attribute (supports single AND double quotes)
..The parent of the current element
When xpath is set to a valid path, x_element points to the name of the element, with x_parent, x_namespace, x_prefix, x_child_name, x_child_namespace, x_child_prefix, x_child_x_text, and x_text providing other properties of the element. The attributes of the current element are provided in the attr_name, attr_namespace, attr_prefix, and attr_value properties.

build_dom must be set to True prior to parsing the document for the xpath functionality to be available.

Example (Setting XPath):

Document rootXML.XPath = "/"
Specific ElementXML.XPath = "/root/SubElement1/SubElement2/"
i-th ChildXML.XPath = "/root/SubElement1[i]"

Input Properties

The class will determine the source of the input based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found, the search stops.

If parsing multiple documents call reset between documents to reset the parser.

put_attr Method

Writes an XML attribute.

Syntax

def put_attr(name: str, namespace_uri: str, value: str) -> None: ...

Remarks

Writes an XML attribute on the currently opened XML element. It must be called right after calling start_element and before any calls to put_string, put_comment or put_raw.

If Name is a local name without a prefix, the class will automatically introduce a new xmlns="NamespaceURI" attribute if necessary.

If Name is in the form prefix:local, then class will automatically introduce a new xmlns:prefix="NamespaceURI" as necessary.

Certain attribute names will be handled in special ways by this method. If Name is "xmlns" or uses the "xmlns" prefix, the attribute will be interpreted as a namespace declaration, regardless of the value of NamespaceURI. Similarly, any attribute using the "xml" prefix will be interpreted as a special attribute (like "xml:lang") and NamespaceURI will be ignored.

put_c_data Method

Writes an XML CDATA block.

Syntax

def put_c_data(text: str) -> None: ...

Remarks

Writes a new XML CDATA block with the specified text inside the current element.

put_comment Method

Writes an XML comment block.

Syntax

def put_comment(text: str) -> None: ...

Remarks

Writes a new XML comment block with the specified text.

put_element Method

Writes a simple XML element with a value.

Syntax

def put_element(name: str, namespace_uri: str, value: str) -> None: ...

Remarks

Writes a simple XML element with no attributes and the specified value between the opening and closing tags.

If Name is a local name without a prefix, the class will automatically introduce a new xmlns="NamespaceURI" attribute if necessary.

If Name is in the form prefix:local, then class will automatically introduce a new xmlns:prefix="NamespaceURI" as necessary.

When calling put_element or start_element, if a NamespaceURI is not specified an empty namespace will be defined for the element. If a namespace should be associated with the element, a NamespaceURI value must be provided. When creating the XML, the class will determine if the namespace already exists to avoid duplicate definitions of the same namespace. For example, to create this XML:

<book xmlns='urn:loc.gov:books'
      xmlns:isbn='urn:ISBN:0-395-36341-6'>
    <title>Cheaper by the Dozen</title>
    <isbn:number>1568491379</isbn:number>
</book>
Use the code: xml.StartElement("book", "urn:loc.gov:books"); xml.PutAttr("xmlns:isbn", "", "urn:ISBN:0-395-36341-6"); xml.PutElement("title", "urn:loc.gov:books", "Cheaper by the Dozen"); xml.PutElement("isbn:number", "urn:ISBN:0-395-36341-6", "1568491379"); xmlw.Close(); In the above example the "title" element uses the default namespace "urn:loc.gov:books" and the "number" element uses the "urn:ISBN:0-395-36341-6" namespace as defined for the "isbn" prefix.

put_raw Method

Writes a raw XML fragment.

Syntax

def put_raw(text: str) -> None: ...

Remarks

Writes a raw XML fragment to the output, without escaping and without verification. If an XML element opening tag has been written, before the raw fragment, the fragment will be written as a child of the current element.

Use of this method should be carefully considered as it can easily lead to malformed XML content.

put_string Method

Writes text inside an XML element.

Syntax

def put_string(text: str) -> None: ...

Remarks

This method will XML escape the value provided and write the resulting escaped text between the opening and closing tags of an XML element.

remove_attr Method

Remove a attribute.

Syntax

def remove_attr(attr_name: str) -> None: ...

Remarks

This method removes an attribute at the specified xpath

This functionality is not yet implemented.

remove_children Method

Removes the children of the elment as the specified XPath.

Syntax

def remove_children() -> None: ...

Remarks

This method removes the children of the element specified by xpath.

When called the class will remove the children of the element from the internal representation of the XML (the DOM). The element itself remains, with no children. This may be used at any time after parse returns, or from within the on_end_element event as a document is parsed in order to remove sections of a document that will not be needed later. By removing unnecessary elements from the DOM memory consumption is reduced and overall performance is improved.

RemoveChildren Example:

Given the XML

<food>
	<fruits>
		<apple>
			<color>red</color>
		</apple>
		<banana>
			<color>yellow</color>
		</banana>
	</fruits>
</food>

This code removes the children of the apple element while leaving the apple element in place.

xml.XPath = "/food/fruits/apple"; xml.RemoveChildren();

The XML stored in the DOM is now:

<food>
	<fruits>
		<apple>
		</apple>
		<banana>
			<color>yellow</color>
		</banana>
	</fruits>
</food>

remove_element Method

Removes the elment as the specified XPath.

Syntax

def remove_element() -> None: ...

Remarks

This method removes the element specified by xpath.

When called the class will remove the element and its children from the internal representation of the XML (the DOM). This may be used at any time after parse returns, or from within the on_end_element event as a document is parsed in order to remove sections of a document that will not be needed later. By removing unnecessary elements from the DOM memory consumption is reduced and overall performance is improved.

RemoveElement Example:

Given the XML

<food>
	<fruits>
		<apple>
			<color>red</color>
		</apple>
		<banana>
			<color>yellow</color>
		</banana>
	</fruits>
</food>

This code removes the apple element and its children.

xml.XPath = "/food/fruits/apple"; xml.RemoveElement();

The XML stored in the DOM is now:

<food>
	<fruits>
		<banana>
			<color>yellow</color>
		</banana>
	</fruits>
</food>

reset Method

Resets the parser.

Syntax

def reset() -> None: ...

Remarks

When called, the parser flushes all its buffers, firing events as necessary, and then initializes itself to its default state.

reset must also be used as signal to the parser that the current stream of text has terminated.

save Method

Closes the class writing stream.

Syntax

def save() -> None: ...

Remarks

This method will close any open XML elements, and then close the output_file if necessary.

save_dom Method

Saves the DOM to a file.

Syntax

def save_dom(file_name: str) -> None: ...

Remarks

The save_dom method saves the current DOM structure to the file specified in FileName. This enables the component to later load the DOM without incurring any parsing overhead.

Please refer to the load_dom method for more information.

start_element Method

Writes the opening tag of an XML element.

Syntax

def start_element(name: str, namespace_uri: str) -> None: ...

Remarks

Writes the opening tag of a new XML element. If an XML element is already opened, then this element is written as a child.

If Name is a local name without a prefix, the class will automatically introduce a new xmlns="NamespaceURI" attribute if necessary.

If Name is in the form prefix:local, then class will automatically introduce a new xmlns:prefix="NamespaceURI" as necessary.

When calling put_element or start_element, if a NamespaceURI is not specified an empty namespace will be defined for the element. If a namespace should be associated with the element, a NamespaceURI value must be provided. When creating the XML, the class will determine if the namespace already exists to avoid duplicate definitions of the same namespace. For example, to create this XML:

<book xmlns='urn:loc.gov:books'
      xmlns:isbn='urn:ISBN:0-395-36341-6'>
    <title>Cheaper by the Dozen</title>
    <isbn:number>1568491379</isbn:number>
</book>
Use the code: xml.StartElement("book", "urn:loc.gov:books"); xml.PutAttr("xmlns:isbn", "", "urn:ISBN:0-395-36341-6"); xml.PutElement("title", "urn:loc.gov:books", "Cheaper by the Dozen"); xml.PutElement("isbn:number", "urn:ISBN:0-395-36341-6", "1568491379"); xmlw.Close(); In the above example the "title" element uses the default namespace "urn:loc.gov:books" and the "number" element uses the "urn:ISBN:0-395-36341-6" namespace as defined for the "isbn" prefix.

try_xpath Method

Navigates to the specified XPath if it exists.

Syntax

def try_xpath(xpath: str) -> bool: ...

Remarks

This method will attempt to navigate to the specified XPath parameter if it exists within the document.

If the XPath exists the xpath property will be updated and this method returns True.

If the XPath does not exist the xpath property is not updated and this method returns False.

XML Config Settings

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

XML Config Settings

CacheContent:   If true, the original XML is saved in a buffer.

This config controls whether or not the component retains the entire original XML in a buffer. This is used to retain the original XML as opposed to returning generated XML after parsing. The default value is true.

Charset:   Specifies the charset used when encoding data.

This setting specifies the character set used when encoding data. This value will also be used when creating the xml_declaration. The default value is "utf-8".

EOL:   The characters to use for separating lines.

If specified, the class will format the output XML, using the specified characters to separate multiple lines for nested XML elements. The default value is CRLF ("\r\n") .

This option should be combined with Indent for full effect.

ErrorOnEmptyAttr:   If true, passing an invalid attribute to the Attr method will throw an exception.

If an invalid attribute name is passed into the get_attr method, the method will return with an empty string if this is set to false, otherwise an exception is thrown.

ExtraNameChars:   Extra characters for the parser to consider as name characters.

Normally, the parser considers only the following characters as part of an XML identifier: 'A' through 'Z', 'a' through 'z', '0' through '9', and '.', '-', '_', ':'.

If you would like any other characters to be considered as name characters, you may set them as a string into this property.

ExtraSpaceChars:   Extra characters for the parser to consider as white space.

Normally, the parser considers only the following characters as white space: ' ' (space), '\t' (tab), '\ n' (newline), '\r' (carriage return), '\f' (form feed), and '\v' (vertical tab).

If you would like any other characters to be considered as white space, you may set them as a string into this property.

FlushOnEOL:   If set, the parser flushes its text buffer after every line of text.

The FlushOnEOL property controls whether on_characters events are fired for every line of the input text stream or not. Normally lines are buffered internally and delivered in batches, but if the FlushOnEOL flag is set, then a on_characters event is fired for each line.

IgnoreBadAttributePrefixes:   If true, bad (unknown) attribute prefixes are ignored.

Normally a trappable error is generated when an unknown attribute prefix is encountered. This setting suppresses the error. The default value is True.

IgnoreBadElementPrefixes:   If true, bad (unknown) element prefixes are ignored.

Normally a trappable error is generated when an unknown element prefix is encountered. This setting suppresses the error. The default value is True.

IncludeElementPrefix:   Whether to include the prefix in the element name.

This setting specifies whether to include the element prefix in the Element parameter of the on_start_element and on_end_element events.

If False (default) and validate is set to False the prefix is included in the Element parameter. For instance: ds:DigestMethod

If True and validate is set to False the prefix is not included in the Element parameter. For instance: DigestMethod

This setting is only applicable when validate is False.

IncludeXMLDeclaration:   Whether to include the XML declaration when writing XML.

This setting specifies whether the XML declaration is included in the output XML when writing XML. When set to True (default) the XML declaration will be included above any user specified XML. For instance:

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
...
Indent:   The characters to use for each indentation level.

If specified, the class will format the output XML, using the specified characters to denote each indentation level for nested XML elements.

This option should be combined with EOL for full effect.

Offset:   Current offset of the document being parsed.

This property is useful for determining the location of possible XML errors in the document.

Offset values start at 1.

PreserveWhitespace:   If true, leading and trailing whitespace in element text is preserved.

Normally the leading and trailing whitespace from an element's text is trimmed. When this property is set to true, this leading and trailing whitespace is preserved. The default value is false.

QuoteChar:   Quote character to use for attribute values.

By default, the class will use double quotes around attribute values. This property can be used to specify a different character such as a single quote.

StringProcessingOptions:   Defines options to use when processing string values.

This setting determines what additional processing is performed on string values fired through the on_characters event..

Note: This only applies when build_dom is False.

By default no additional processing is performed and the string is returned as is from the document. Strings may also be XML unescaped. Possible values are:

0 (none - default) No additional processing is performed.
1 Strings are XML unescaped.

For instance, when set to 0 the following text may be fired through the on_characters event:

&amp;&quot;&lt;&gt;

When set to 1 the following text would be fired through the on_characters event:

&"<>

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to True to mask sensitive data. The default is True.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when do_events is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to False, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to True tells the class to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to False by default. On Linux/macOS, this setting is set to True by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
