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, XElement points to the name of the element, with XParent, XNamespace, XPrefix, XChildName, XChildNamespace, XChildPrefix, XChildXText, and XText providing other properties of the element. The attributes of the current element are provided in the AttrName, AttrNamespace, AttrPrefix, and AttrValue properties.

BuildDOM 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]"

Data Type

String

Close Method (OfficeDoc Class)

Closes the Open XML package archive.

Syntax

ANSI (Cross Platform)
int Close();

Unicode (Windows)
INT Close();
- (void)close;
int ipworkszip_officedoc_close(void* lpObj);

Remarks

When this method is called, the class will close the current archive and release all resources.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Config Method (OfficeDoc Class)

Sets or retrieves a configuration setting.

Syntax

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(const wchar_t* lpszConfigurationString);
- (NSString*)config:(NSString*)configurationString;
char* ipworkszip_officedoc_config(void* lpObj, const char* lpszConfigurationString);

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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

ExtractPart Method (OfficeDoc Class)

If the part doesn't exists, or it's stored in interleaved format, an error will be raised.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

- (NSString*)findPartByType:(NSString*)typeURI;
char* ipworkszip_officedoc_findpartbytype(void* lpObj, const char* lpszTypeURI);

Remarks

If a matching part can be found, it's part name is returned. Otherwise, an empty string is returned.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

GetPropertyValue Method (OfficeDoc Class)

Remarks

Looks up a package property named PropName in namespace PropNamespace in the core and app properties tables and returns it's value, if found.

If the property doesn't exists, an empty string is returned.

For custom properties. use an empty string ("") as the value of the PropNamespace parameter.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Remarks

If the part specified by PartName exists, the corresponding physical file will be extracted from the archive and parsed as XML. If BuildDOM is enabled, the DOM will be built internally and you can use XPath to query the resulting document, using the XPath property. If BuildDOM is disabled, only the XML parser-related events will be fired.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

- (void)onMeta:(NSString*)text;
#define EID_OFFICEDOC_META 10

virtual INT IPWORKSZIP_CALL FireMeta(LPSTR &lpszText);

Remarks

The Meta event is fired whenever a meta information section (<! ..text... >) is found in the document.

The full text of the meta section is provided by the Text parameter.

Overwrite Event (OfficeDoc Class)

Fired whenever a file exists and may be overwritten.

Syntax

ANSI (Cross Platform)
virtual int FireOverwrite(OfficeDocOverwriteEventParams *e);

- (void)onOverwrite:(NSString**)filename :(int*)overwrite;
#define EID_OFFICEDOC_OVERWRITE 11

virtual INT IPWORKSZIP_CALL FireOverwrite(LPSTR &lpszFilename, BOOL &bOverwrite);

Remarks

Overwrite is fired when a file is about to be overwritten, and would overwrite an existing file. The event is fired during decompression.

Filename contains the full name of the file, specified with its pathname.

Overwrite specifies whether or not the file will be overwritten. For Zip, Jar, and Tar, this is equal by default to the value of the OverwriteFiles property. For Gzip, this value defaults to true.

Either of the parameters may be changed when the event is fired. Changing the value of Overwrite will override the default behavior of the class, and cause the file to be overwritten or not overwritten, depending on the value set. If Filename is changed, the value of Overwrite will be ignored, and the file will be written with the specified name. If a file of the new name also exists this file will be silently overwritten.

PI Event (OfficeDoc Class)

Fired when a processing instruction section is encountered.

Syntax

ANSI (Cross Platform)
virtual int FirePI(OfficeDocPIEventParams *e);

int64 BytesProcessed;
int PercentProcessed; int reserved; } OfficeDocProgressEventParams;
Unicode (Windows) virtual INT FireProgress(OfficeDocProgressEventParams *e);
typedef struct {
LPCSTR Data; INT lenData;
LPCWSTR Filename;
LONG64 BytesProcessed;
INT PercentProcessed; INT reserved; } OfficeDocProgressEventParams;
- (void)onProgress:(NSData*)data :(NSString*)filename :(long long)bytesProcessed :(int)percentProcessed;
#define EID_OFFICEDOC_PROGRESS 13

virtual INT IPWORKSZIP_CALL FireProgress(LPSTR &lpData, INT &lenData, LPSTR &lpszFilename, LONG64 &lBytesProcessed, INT &iPercentProcessed);

Remarks

The Progress event is automatically fired as compression or decompression is performed. When WriteToProgressEvent is true, the output data is provided through the Data parameter, allowing for it to be streamed out.

Filename contains the name of the file being written. If no file is being written, Filename will contain an empty string, and the output data will be provided exclusively through this event.

BytesProcessed contains the total number of uncompressed bytes processed. PercentProcessed contains the percent of uncompressed bytes processed, corresponding roughly to the running time of the operation.

For Gzip extraction only, BytesProcessed and PercentProcessed will reflect the number of compressed bytes extracted, as it is generally impossible to predetermine the total uncompressed size.

If WriteToProgressEvent is false, Data will contain null.

SpecialSection Event (OfficeDoc Class)

Fired when a special section is encountered.

Syntax

ANSI (Cross Platform)
virtual int FireSpecialSection(OfficeDocSpecialSectionEventParams *e);

Remarks

The EndPrefixMapping event is fired when leaving the scope of a namespace declaration.

Configuration Settings (OfficeDoc Class)

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.

OfficeDoc Configuration Settings

NormalizePartName:   Whether to normalize Part Names.

Sometimes the Part Names retrieved from a document will be of a format that is not directly usable in the PartName property when retrieving the part. For example: /ppt/slides/../media/image1.jpeg

When this option is set to True the component will automatically normalize these Part Names so that they can be directly used in the PartName property for retrieving the part. For example, the above would become: /ppt/media/image1.jpeg

The default is True.

RelationshipIsExternal[x]:   Whether the relationship part is internal or external.

Some relationships in an Office document may be external items, such as URLs and files on disk. These relationships are not directly accessible via ExtractPart. This configuration option will return "1" if the relationship at index "x" of the Relationship* arrays is an external part. Otherwise it will return "0"

Base Configuration 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).

The following is a list of valid code page identifiers:

IdentifierName
037IBM EBCDIC - U.S./Canada
437OEM - United States
500IBM EBCDIC - International
708Arabic - ASMO 708
709Arabic - ASMO 449+, BCON V4

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.
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 DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

By default the class will use the system security libraries to perform cryptographic functions where applicable. Setting this to true tells the class to use the internal implementation instead of using the system's security API.

Trappable Errors (OfficeDoc Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Errors

The following errors may be generated by the class. Note that frequently the error message will contain more specific information than what is listed here.

Note that some non-fatal errors may be trapped and explicitly ignored in the Error event. This will allow the class to continue operation even in case of error.

OfficeDoc Errors
