Image::ExifTool::TagInfoXML(3)             User Contributed Perl Documentation


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.
