KeyView 23.4

# KVXMLConfig()

This function is called directly and provides a way to configure options prior to the document conversion. Currently, the function is used for the following configurations:

- Generate output without images

  Generate output with verbose markup and without images. To generate output with minimal markup (ID and style paragraph attributes) and without images, set the `bIndexOnly` member of the `KVXMLOptions` structure. See KVXMLOptions.

- Enable PDF position information

  Include position information in the markup generated for a PDF document.

- Configure PDF bookmarks

  Specify whether bookmarks in a PDF file are converted to simple XLinks in the XML output.

- Configure Word bookmarks

  Disable the conversion of Microsoft Word bookmarks to zone elements.

- Designate temporary directory

  Specify a directory in which temporary files created during XML conversion processes are stored.

- Configure XML conversion

  Specify the elements and attributes extracted from an XML document based on the files document type.

- Enable PDF logical reading order

  Convert paragraphs in PDF files in the order in which they appear on the page and with left-to-right or right-to-left paragraph direction. See Convert PDF Files to a Logical Reading Order.

- Configure PDF soft hyphens

  Specify whether soft hyphens are removed from the XML output. See Control Hyphenation.

- Enable Revision Marks

  Convert text and graphics that were deleted from a document with revision tracking enabled and include revision tracking information in the XML output. Convert Revision Tracking Information.

- Protected file password

  Specify the password to use to open a password-protected file for export.

- Specify output character set for summary information

  Specify the output character set for the document's metadata, when using `fpGetSummaryInfo()`.

- Include position and invisible text tokens (with bounding boxes) in the output

  Add top, left, height, width, and rotation attributes to `<p>` elements.

- Enable or disable Optical Character Recognition (OCR)

  KeyView can perform Optical Character Recognition (OCR) on raster image files - see KVCFG_OCR in the table below.

## Syntax

    KVErrorCode pascal KVXMLConfig(
        void    *pContext,
        int      nType,
        int      nValue,
        void    *p );

## Arguments

`pContext` | A pointer to a KeyView Export session that you initialized by calling fpInit().
`nType` | The configuration flag. This is a symbolic constant defined in `kvtypes.h`. The available options are described in Configuration Flags.
`nValue` | The integer value defined for the flags above. This is `TRUE` or `FALSE` for all flags except `KVCFG_LOGICALPDF`, `KVCFG_SETMETADATACHARSET`, `KVCFG_SETTEMPDIRECTORY`, and `KVCFG_SETXMLCONFIGINFO`. For `KVCFG_LOGICALPDF`, this is one of the paragraph direction options defined in the `LPDF_DIRECTION` enumerated type in `kvtypes.h`. See LPDF_DIRECTION. For `KVCFG_SETTEMPDIRECTORY` and `KVCFG_SETXMLCONFIGINFO`, this is not set. For `KVCFG_SETMETADATACHARSET`, `nValue` is a character set enumerated in `KVCharSet` in `kvcharset.h`. See Convert Character Sets.
`p` | The data for the configuration flag. This is `NULL` for all flags except `KVCFG_SETTEMPDIRECTORY` and `KVCFG_SETXMLCONFIGINFO`. For `KVCFG_SETTEMPDIRECTORY`, this is path to the directory where temporary files are stored. For `KVCFG_SETXMLCONFIGINFO`, this is a pointer to the `KVXConfigInfo` structure. See KVXConfigInfo. For `KVCFG_SETPASSWORD`, this is the source file password.

## Configuration Flags

The following flags are available for the `nType` argument in `KVXMLConfig()`. These flags are defined in `kvtypes.h`.

Flag | Description
--- | ---
`KVCFG_SUPPRESSIMAGES` | If you set `KVCFG_SUPPRESSIMAGES`, the XML output includes verbose markup, but no images. If you do not set this option, embedded images in a document are regenerated as separate files and stored in the output directory. To generate output with minimal markup (ID and style paragraph attributes) and without images, set the `bIndexOnly` member of the `KVXMLOptions` structure to `TRUE`. KVXMLOptions.
`KVCFG_ENABLEPOSITIONINFO` | If you set `KVCFG_ENABLEPOSITIONINFO`, a position element is included in the markup for PDF documents. The position element defines the absolute position of the text relative to the bottom left corner of the page, and includes additional information such as font and color.
`KVCFG_SETMETADATACHARSET` | This option enables you to specify the output character set for metadata when using `fpGetSummaryInfo()`. `nValue` is a character set enumerated in `KVCharSet` in `kvcharset.h`. See Convert Character Sets. This function should be called before `fpGetSummaryInfo()`.
`KVCFG_SUPPRESSTOCPRINTIMAGE` | If you set `KVCFG_SUPPRESSTOCPRINTIMAGE`, bookmarks in a PDF file are not converted to simple XLinks in the XML output. By default, PDF bookmarks are converted to source and destination anchors. For example,
    <a xmlns:xlink="http://www.w3.org/TR/xlink" xlink:href="#bmk1">Highlight File Format</a>
    <a xmlns:xlink="http://www.w3.org/TR/xlink" name="bmk1"><img src="pdf14640.jpg"/>
`KVCFG_DISABLEZONE` | If you set `KVCFG_DISABLEZONE`, the conversion of Microsoft Word bookmarks to zone elements (`<zone name ="xxx"`>) in the output XML is disabled. A bookmark in Microsoft Word documents is a name given to a selected area of the document. The bookmark might enclose words, paragraphs, tables, table cells, lists, list items, or the entire document. In XML Export, bookmarks are converted to zone elements (`<Zone name="xxx">`) by using the KeyView `KVT_ZONE` token. Depending on how bookmarks are defined in the original document, the creation of zone elements might result in malformed XML. In this case, you can disable zone creation to avoid these validity errors. Zone element creation is enabled by default.
`KVCFG_SETTEMPDIRECTORY` | The `KVCFG_SETTEMPDIRECTORY` flag enables you to specify the directory in which temporary files created during conversion processes are stored. By default, the system temporary directory is used. To define a directory for temporary files generated during an out-of-process conversion, set the `tempfilepath` parameter in the `formats_e.ini` file. See Convert Files Out of Process. On Windows, `p` must be in the local Windows code page. To set `KVCFG_SETTEMPDIRECTORY` when converting out-of-process, call this function before you call KVXMLStartOOPSession().
`KVCFG_SETXMLCONFIGINFO` | The `KVCFG_SETXMLCONFIGINFO` flag enables you to define which elements and attributes are extracted from XML documents with a specified format ID or root element. You can use this to override the default settings for the supported XML formats (see Convert XML Files), or to define settings for custom XML document types. The settings are defined in the `KVXConfigInfo` structure (see KVXConfigInfo). To set custom settings for more than one document type, call the `KVXMLConfig()` function once for each type. You can also modify element extraction settings by using the `kvxconfig.ini` file. See Configure Element Extraction for XML Documents.
`KVCFG_LOGICALPDF` | The `KVCFG_LOGICALPDF` flag converts paragraphs in a PDF file in the order in which they appear on the page (logical reading order). The `nValue` argument specifies the paragraph direction. See Convert PDF Files to a Logical Reading Order.
`KVCFG_DELSOFTHYPHEN` | If you set `KVCFG_DELSOFTHYPHEN`, soft hyphens in the source document are removed, and the hyphenated words are joined in the XML output. By default, soft hyphens are maintained. See Control Hyphenation. OpenText recommends that you remove soft hyphens if you use Export to generate text output for an indexing engine or are not concerned with maintaining the document's layout. See fpConvertStream() or KVXMLConvertFile() for more information on running Export in index mode.
`KVCFG_INCLREVISIONMARK` | If you set this flag to `TRUE`, text and graphics that were deleted from a document with a revision tracking feature enabled are converted, and revision tracking information is included in the XML output. To reset the flag and exclude deleted content and revision tracking information from the XML output, set the flag to `FALSE`. See Convert Revision Tracking Information. The default is `FALSE`.
`KVCFG_WP_NOCOMMENTS` | Set `KVCFG_WP_NOCOMMENTS` to `TRUE` not to export text from comments in Microsoft Word documents. Comment text is exported by default from Microsoft Word 97 to 2003 files. You can also toggle comment output by modifying the `formats_e.ini` file. See Show Hidden Data.
`KVCFG_WP_SHOWHIDDENTEXT` | Set `KVCFG_WP_SHOWHIDDENTEXT` to `TRUE` to export hidden text from Microsoft Word documents.
`KVCFG_WP_SHOWDATEFIELDCODE` | Set `KVCFG_WP_SHOWDATEFIELDCODE` to `TRUE` to export date field codes from Microsoft Word documents.
`KVCFG_WP_SHOWFILENAMEFIELDCODE` | Set `KVCFG_WP_SHOWFILENAMEFIELDCODE` to `TRUE` to export the file name field code from Microsoft Word documents.
`KVCFG_SS_SHOWHIDDENINFOR` | Set `KVCFG_SS_SHOWHIDDENINFOR` to `TRUE` to export hidden information from Microsoft Excel files.
`KVCFG_SS_SHOWCOMMENTS` | Set `KVCFG_SS_SHOWCOMMENTS` to `TRUE` to export comments from Microsoft Excel files.
`KVCFG_SS_SHOWFORMULA` | Set `KVCFG_SS_SHOWFORMULA` to `TRUE` to export formulas from Microsoft Excel files.
`KVCFG_PG_HIDEHIDDENSLIDE` | Set `KVCFG_PG_HIDEHIDDENSLIDE` to `TRUE` not to export hidden slides from Microsoft PowerPoint files.
`KVCFG_PG_HIDECOMMENT` | Set `KVCFG_PG_HIDECOMMENT` to `TRUE` not to export comments from Microsoft PowerPoint files. Comments are exported by default from PowerPoint 97 to 2000 files.
`KVCFG_PG_SHOWCOMMENTSSLIDE` | Set `KVCFG_PG_SHOWCOMMENTSSLIDE` to `TRUE` to export comments slides from Microsoft PowerPoint 2003 and 2007 files.
`KVCFG_PG_SHOWSLIDNOTES` | Set `KVCFG_PG_SHOWSLIDNOTES` to `TRUE` to export slide notes from Microsoft PowerPoint files. You can also toggle slide note output by modifying the `formats_e.ini` file. See Show Hidden Data.
`KVCFG_SETPASSWORD` | This flag enables you to define a password used to open a password-protected file for export. See Export Password Protected Files. `nValue` is `TRUE`. `p` is the source file password, which can have a maximum length of 255 characters (the final byte is null).
`KVCFG_POSITIONINFOOUTPUTTYPE` | This flag enables you to extend the existing `<p>` tags to include bounding box information.
`KVCFG_OCR` | Specifies whether to perform Optical Character Recognition (OCR) on raster image files, to extract machine-printed text from the image. The output from XML Export includes the original image, exported to the format you specify in KVXMLOptions, and any text extracted by OCR inside `<ocr>` tags. If OCR detects that some of the text forms a table, it will be included in the output as a `<table>`. OCR is available only on certain platforms (see Optical Character Recognition in the platform differences section). OCR processes only standalone raster images and not subfiles, such as images embedded in a Word document. If your license includes OCR, it is enabled by default. To disable OCR, set this flag to `FALSE`.

## Returns

The return value is one of the error codes defined in `KVErrorCode` in `kverrorcodes.h`.

## Discussion

- You must call this function after the call to fpInit() and before the call to `fpConvertStream()` or `KVXMLConvertFile()`.

- This function runs in-process or out of process. See Convert Files Out of Process.

- When converting out-of-process, you must call this function after the call to KVXMLStartOOPSession() and before the call to KVXMLEndOOPSession(). The exception is when setting `KVCFG_SETTEMPDIRECTORY` - in which case, call this function before the call to `KVXMLStartOOPSession()`.

## Examples

- To generate verbose markup, but no images:

      (*fpXMLConfig)(pKVXML, KVCFG_SUPPRESSIMAGES, TRUE, NULL);

- To produce summary information in UTF8:

      (*fpXMLConfig)(pKVXML, KVCFG_SETMETADATACHARSET, KVCS_UTF8, NULL);

- To specify bookmarks in a PDF file are not converted to XLinks in the XML output:

      (*fpXMLConfig)(pKVXML, KVCFG_SUPPRESSTOCPRINTIMAGE, TRUE, NULL);

- To disable the conversion of zone elements:

      (*fpXMLConfig)(pKVXML, KVCFG_DISABLEZONE, TRUE, NULL);

- To set a directory for temporary files:

      char     tmpDir[250];
      strcpy (tmpDir, "c:\\temp\\xmlexport");
      (*fpXMLConfig)(pKVXML, KVCFG_SETTEMPDIRECTORY, 0, tmpDir);

- To specify custom extraction settings for conversion of an XML file:

      KVXConfigInfo  xinfo;  /* populate xinfo */
      (*fpXMLConfig)(pKVXML, KVCFG_SETXMLCONFIGINFO, 0, &xinfo);

- To specify PDF files are converted to a logical reading order, and the paragraph direction for the PDF output is left to right:

      (*fpXMLConfig)(pKVXML, KVCFG_LOGICALPDF, LPDF_LTR, NULL);

- To specify PDF files are converted to a logical reading order, and the paragraph direction for the PDF output is right to left:

      (*fpXMLConfig)(pKVXML, KVCFG_LOGICALPDF, LPDF_RTL, NULL);

- To specify PDF files are converted to a logical reading order, and the paragraph direction for the PDF output is determined on the fly for each page:

      (*fpXMLConfig)(pKVXML, KVCFG_LOGICALPDF, LPDF_AUTO, NULL);

- To specify soft hyphens are removed from the XML output:

      (*fpXMLConfig)(pKVXML, KVCFG_DELSOFTHYPHEN, TRUE, NULL);

- To convert text and graphics that are identified by revison marks:

      (*fpXMLConfig)(pKVXML, KVCFG_INCLREVISIOMARK, TRUE, NULL);

- To toggle hidden data output from Microsoft Word documents, use one of the `KVCFG_WP` flags:

      (*fpXMLConfig)(pKVXML, KVCFG_WP_NOCOMMENTS, TRUE, NULL);

- To toggle hidden data output from Microsoft Excel documents, use one of the `KVCFG_SS` flags:

      (*fpXMLConfig)(pKVXML, KVCFG_SS_SHOWHIDDENINFOR, TRUE, NULL);

- To toggle hidden data output from Microsoft PowerPoint documents, use one of the `KVCFG_PG` flags:

      (*fpXMLConfig)(pKVXML, KVCFG_PG_HIDEHIDDENSLIDE, TRUE, NULL);

- To specify a password to open a password-protected file for export:

      (*fpXMLConfig)(pKVXML, KVCFG_SETPASSWORD, TRUE, password);

  where `password` is a null-terminated string of 255 or fewer characters.

- To include a position element in the markup for PDF documents:

      (*fpXMLConfig)(pKVXML, KVCFG_ENABLEPOSITIONINFO, TRUE, NULL);

  Using the PDF position element significantly changes the generated markup. For example, without the option, the XML output from a section of a PDF document looks like this:

      <?xml version="1.0" encoding="utf-8" ?>
        <!DOCTYPE VerityXMLExport (View Source for full doctype...)>
      - <VerityXMLExport>
      - <WP>
      - <p id="p1" font-size="33pt">
        <img src="ecpe.pdf38760.jpg" height="140px" width="292px" />
        Economic Fiscal Update
        <font size="18pt" color="#777777">Theand</font>
        <font size="14pt" color="#ffffff">October 30, 2002</font>
        <font size="29pt" color="#a4a4a4">Overview</font>
        </p>

  With the option enabled, the same section of the PDF document looks like this:

      <?xml version="1.0" encoding="utf-8" ?>
        <!DOCTYPE VerityXMLExport (View Source for full doctype...)>
      - <VerityXMLExport>
      - <WP>

        Overview

- To include position information in attributes of `<p>` tags:

      (*fpXMLConfig)(pKVXML, KVCFG_ENABLEPOSITIONINFO, TRUE, NULL);
      (*fpXMLConfig)(pKVXML, KVCFG_POSITIONINFOOUTPUTTYPE, KVPIOT_ATTRIBUTES, NULL);

  In this mode, each piece of content output by the reader with a position is put in its own `<p>` element. Line break (`<br/>`) tags are not included in the output.

  The `<p>` tags have position information, when this information is available from the reader. These are included in new attributes of the`<p>` tag: `top`, `left`, `height`, `width`, and `rotation`.

  The `top`, `left`, `width`, and `height` attributes are all expressed in pixels. The `top` and `left` attributes give the coordinates of the top left corner of the content (an image, text box, and so on) relative to the top left corner of the page. The `width` and `height` attributes are the width and height of the content.

  Rotation is expressed in degrees, and gives the clockwise rotation of the content about the top left corner. If the `rotation` attribute is not present, the rotation is assumed to be zero.

  NOTE: Not all readers output all these attributes for all pieces of content. Only `pdf2sr` outputs width, height and rotation information for text. `pdf2sr` does not put `height` and `width` attributes on `<p>` tags that enclose images; rather, the `<img>` tags themselves have the height and width. For example:

      <p id="p1" font-size="12pt" top="0px" left="0px"><img src="103453.pdf00.png" height="1261px" width="892px"/></p>
      <p id="p2" font-family="MyriadPro-It" font-size="16pt" top="59px" left="129px" height="21px" width="447px"><i>Aufforderung zur Einreichung von Vorschlägen 2005:
