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 before parsing the document for the XPath functionality to be available.

Config Method (OfficeDoc Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.

ExtractPart Method (OfficeDoc Component)

Reads the contents of the currently selected part.

Syntax

void __fastcall ExtractPart();

Remarks

If the part specified by the PartName property exists, the corresponding physical file will be extracted from the archive and will be available through the PartData property.

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

FindPartByType Method (OfficeDoc Component)

Looks up a part in the current relationships file by it's type namespace URI.

Syntax

String __fastcall FindPartByType(String TypeURI);

Remarks

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

GetPropertyValue Method (OfficeDoc Component)

Syntax

String __fastcall GetPropertyValue(String PropName, String PropNamespace);

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.

ListParts Method (OfficeDoc Component)

List all the parts contained in the document and their relationships.

Syntax

void __fastcall ListParts();

Remarks

When this method is called, the component will read all the relationships in the document, recursively, and populate the Relationships collection.

Open Method (OfficeDoc Component)

Opens the Open XML package archive.

Syntax

void __fastcall Open();

Remarks

When this method is called, the component will attempt to open the archive specified in PackagePath and extract package properties, content types and parse the master relationships file in the archive.

ParsePart Method (OfficeDoc Component)

Parses the specified part as XML.

Syntax

void __fastcall ParsePart();

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.

ReadRelationships Method (OfficeDoc Component)

Reads the relationships file in the archive associated with the specified part.

Syntax

void __fastcall ReadRelationships();

Replaces the contents of the specified part in the package.

Syntax

void __fastcall ReplacePart();

Remarks

If the part specified by the PartName property exists, the corresponding physical file will be replaced with the contents of the PartData property. The package file will be modified in place right away.

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

Reset Method (OfficeDoc Component)

Resets the component.

Syntax

void __fastcall Reset();

Remarks

Reset resets the state of the component. All properties will be set to their default values, and any files open will be closed.

Syntax

String __fastcall ResolveContentType();

Remarks

Applies the content type resolution rules specified in the Open XML packaging specification and returns the content type associated with PartName in the archive.

If there's no content type mapped for the part or for the extension, an empty string is returned.

BeginFile Event (OfficeDoc Component)

Fired before each file is processed.

Syntax

typedef struct {
  int Index;
  bool Skip;
} TipzOfficeDocBeginFileEventParams;
typedef void __fastcall (__closure *TipzOfficeDocBeginFileEvent)(System::TObject* Sender, TipzOfficeDocBeginFileEventParams *e);
__property TipzOfficeDocBeginFileEvent OnBeginFile = { read=FOnBeginFile, write=FOnBeginFile };

Remarks

BeginFile is fired before each file is processed by the compressor or decompressor, as appropriate. Index contains the array index of the file about to be processed, and the FileCompressedName, FileDecompressedName, FileCompressedSize (decompression only), and FileDecompressedSize fields of the Files collection for this index contain more detailed information about the file about to be processed.

When extracting, an alternate location may be specified by trapping the event, and modifying FileDecompressedName and/or ExtractToPath. If FileDecompressedName is set to an empty string, the file will not be written to disk. If WriteToProgressEvent is true, the file will still be decompressed, and the data may be extracted through the Progress event.

This event may also be trapped while compressing. FileCompressedName and FileDecompressedName may be changed.

You may set the Skip parameter to true in order to skip the file completely while compressing or extracting.

typedef void __fastcall (__closure *TipzOfficeDocEndFileEvent)(System::TObject* Sender, TipzOfficeDocEndFileEventParams *e);
__property TipzOfficeDocEndFileEvent OnEndFile = { read=FOnEndFile, write=FOnEndFile };

Remarks

EndFile is fired after each file is processed by the compressor or decompressor, as appropriate. Index contains the array index of the file processed, and the FileCompressedName, FileDecompressedName, FileCompressedSize, and FileDecompressedSize fields in the Files collection for this index contain more detailed information about the file processed.

EndPrefixMapping Event (OfficeDoc Component)

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

Syntax

typedef struct {
  String Prefix;
} TipzOfficeDocEndPrefixMappingEventParams;
typedef void __fastcall (__closure *TipzOfficeDocEndPrefixMappingEvent)(System::TObject* Sender, TipzOfficeDocEndPrefixMappingEventParams *e);
__property TipzOfficeDocEndPrefixMappingEvent OnEndPrefixMapping = { read=FOnEndPrefixMapping, write=FOnEndPrefixMapping };

Remarks

The StartPrefixMapping event is fired when entering the scope of a namespace declaration.

Error Event (OfficeDoc Component)

Fired when information is available about errors during data delivery.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TipzOfficeDocErrorEventParams;
typedef void __fastcall (__closure *TipzOfficeDocErrorEvent)(System::TObject* Sender, TipzOfficeDocErrorEventParams *e);
__property TipzOfficeDocErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

EvalEntity Event (OfficeDoc Component)

This event is fired every time an entity needs to be evaluated.

Syntax

typedef struct {
  String Entity;
  String Value;
} TipzOfficeDocEvalEntityEventParams;
typedef void __fastcall (__closure *TipzOfficeDocEvalEntityEvent)(System::TObject* Sender, TipzOfficeDocEvalEntityEventParams *e);
__property TipzOfficeDocEvalEntityEvent OnEvalEntity = { read=FOnEvalEntity, write=FOnEvalEntity };

Remarks

The Value parameter contains a suggested value for the entity (normally the entity name itself). You may set Value to a value of your choice, which will be later passed into the text stream.

IgnorableWhitespace Event (OfficeDoc Component)

This event is fired when a section of ignorable whitespace is encountered.

Syntax

typedef struct {
  String Text;
} TipzOfficeDocIgnorableWhitespaceEventParams;
typedef void __fastcall (__closure *TipzOfficeDocIgnorableWhitespaceEvent)(System::TObject* Sender, TipzOfficeDocIgnorableWhitespaceEventParams *e);
__property TipzOfficeDocIgnorableWhitespaceEvent OnIgnorableWhitespace = { read=FOnIgnorableWhitespace, write=FOnIgnorableWhitespace };

Remarks

The ignorable whitespace section is provided by the Text parameter.

Meta Event (OfficeDoc Component)

This event fires when a meta section is encountered.

Syntax

typedef struct {
  String Text;
} TipzOfficeDocMetaEventParams;
typedef void __fastcall (__closure *TipzOfficeDocMetaEvent)(System::TObject* Sender, TipzOfficeDocMetaEventParams *e);
__property TipzOfficeDocMetaEvent OnMeta = { read=FOnMeta, write=FOnMeta };

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 Component)

Fired whenever a file exists and may be overwritten.

Syntax

typedef struct {
  String Filename;
  bool Overwrite;
} TipzOfficeDocOverwriteEventParams;
typedef void __fastcall (__closure *TipzOfficeDocOverwriteEvent)(System::TObject* Sender, TipzOfficeDocOverwriteEventParams *e);
__property TipzOfficeDocOverwriteEvent OnOverwrite = { read=FOnOverwrite, write=FOnOverwrite };

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 component, 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 Component)

This event is fired when a processing instruction section is encountered.

Syntax

typedef struct {
  String Text;
} TipzOfficeDocPIEventParams;
typedef void __fastcall (__closure *TipzOfficeDocPIEvent)(System::TObject* Sender, TipzOfficeDocPIEventParams *e);
__property TipzOfficeDocPIEvent OnPI = { read=FOnPI, write=FOnPI };

Remarks

The PI event is fired whenever a processing instruction section (<? ..text... ?>) is found in the document.

The full text of the processing instruction is provided by the Text parameter.

Progress Event (OfficeDoc Component)

Fired as progress is made.

Syntax

typedef struct {
  String Data;
  DynamicArray<Byte> DataB;
  String Filename;
  __int64 BytesProcessed;
  int PercentProcessed;
} TipzOfficeDocProgressEventParams;
typedef void __fastcall (__closure *TipzOfficeDocProgressEvent)(System::TObject* Sender, TipzOfficeDocProgressEventParams *e);
__property TipzOfficeDocProgressEvent OnProgress = { read=FOnProgress, write=FOnProgress };

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 Component)

This event is fired when a special section is encountered.

Syntax

typedef struct {
  String SectionId;
  String Text;
} TipzOfficeDocSpecialSectionEventParams;
typedef void __fastcall (__closure *TipzOfficeDocSpecialSectionEvent)(System::TObject* Sender, TipzOfficeDocSpecialSectionEventParams *e);
__property TipzOfficeDocSpecialSectionEvent OnSpecialSection = { read=FOnSpecialSection, write=FOnSpecialSection };

Remarks

The SpecialSection event is fired whenever a special section (such as <![ CDATA [ ..text... ]]>) is found in the document.

The full text of the special section is provided by the Text parameter, and the SectionId parameter provides the section identifier (e.g., CDATA).

StartElement Event (OfficeDoc Component)

This event is fired when a begin-element tag is encountered in the document.

Syntax

typedef struct {
  String Namespace;
  String Element;
  String QName;
  bool IsEmpty;
} TipzOfficeDocStartElementEventParams;
typedef void __fastcall (__closure *TipzOfficeDocStartElementEvent)(System::TObject* Sender, TipzOfficeDocStartElementEventParams *e);
__property TipzOfficeDocStartElementEvent OnStartElement = { read=FOnStartElement, write=FOnStartElement };

Remarks

The StartElement event is fired when a begin-element tag is found in the document.

The element name is provided through the Element parameter. The attribute names and values (if any) are provided through the AttrName, AttrNamespace, AttrPrefix, and AttrValue properties.

The IsEmpty parameter is True when the event corresponds to an empty element declaration.

StartPrefixMapping Event (OfficeDoc Component)

This event is fired when entering the scope of a namespace declaration.

Syntax

typedef struct {
  String Prefix;
  String URI;
} TipzOfficeDocStartPrefixMappingEventParams;
typedef void __fastcall (__closure *TipzOfficeDocStartPrefixMappingEvent)(System::TObject* Sender, TipzOfficeDocStartPrefixMappingEventParams *e);
__property TipzOfficeDocStartPrefixMappingEvent OnStartPrefixMapping = { read=FOnStartPrefixMapping, write=FOnStartPrefixMapping };

Remarks

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

Config Settings (OfficeDoc Component)

The component 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 component, access to these internal properties is provided through the Config method.

OfficeDoc Config 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 Relationships is an external part. Otherwise it will return "0"

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 component 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.
MaskSensitiveData:   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 components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

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

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

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

This setting is set to false by default on all platforms.

Trappable Errors (OfficeDoc Component)

Errors

The following errors may be generated by the component. 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 component to continue operation even in case of error.

OfficeDoc Errors

268   The specified part name could not be found on the package, or the part is stored in interleaved format.
