Image::ExifTool::TagInfoXML - phpMan

NAME
    Image::ExifTool::TagInfoXML - Read/write tag information XML database

DESCRIPTION
    This module is used to generate an XML database from all ExifTool tag
    information. The XML database may then be edited and used to re-generate
    the language modules (Image::ExifTool::Lang::*).

METHODS
  Write
    Print complete tag information database in XML format.

      # save list of all tags
      $success = Image::ExifTool::TagInfoXML::Write('dst.xml');

      # list all IPTC tags to console, including Flags
      Image::ExifTool::TagInfoXML::Write(undef, 'IPTC', Flags => 1);

      # write all EXIF Camera tags to file
      Image::ExifTool::TagInfoXML::Write($outfile, 'exif:camera');

    Inputs:
        0) [optional] Output file name, or undef for console output. Output
        file will be overwritten if it already exists.

        1) [optional] String of group names separated by colons to specify
        the group to print. A specific IFD may not be given as a group,
        since EXIF tags may be written to any IFD. Saves all groups if not
        specified.

        2) [optional] Hash of options values:

            Flags   - Set to output 'flags' attribute
            NoDesc  - Set to suppress output of descriptions
            Lang    - Select a single language for output

    Return Value:
        True on success.

    Sample XML Output:

      <?xml version='1.0' encoding='UTF-8'?>
      <taginfo>

      <table name='XMP::dc' g0='XMP' g1='XMP-dc' g2='Other'>
       <desc lang='en'>XMP Dublin Core</desc>
       <tag id='title' name='Title' type='lang-alt' writable='true' g2='Image'>
        <desc lang='en'>Title</desc>
        <desc lang='de'>Titel</desc>
        <desc lang='fr'>Titre</desc>
       </tag>
       ...
      </table>

      </taginfo>

    Flags (if selected and available) are formatted as a comma-separated
    list of the following possible values: Avoid, Binary, List, Mandatory,
    Permanent, Protected, Unknown and Unsafe. See the tag name documentation
    and lib/Image/ExifTool/README for a description of these flags. For XMP
    List tags, the list type (Alt, Bag or Seq) is also output as a flag if
    applicable.

  BuildLangModules
    Build all Image::ExifTool::Lang modules from an XML database file.

        Image::ExifTool::TagInfoXML::BuildLangModules('src.xml');

    Inputs:
        0) XML file name

        1) Update flags:

            0x01 = preserve version numbers
            0x02 = update all modules, even if they didn't change
            0x04 = update from scratch, ignoring existing definitions
            0x08 = override existing different descriptions and values

    Return Value:
        Number of modules updated, or negative on error.
