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

       Copyright 2003-2025, Phil Harvey (philharvey66 at gmail.com)

       This  library  is  free  software;  you can redistribute it and/or modify it under the same terms as Perl
       itself.

       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::*).

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.
