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. This database may then be edited and used to re-generate
       the localized tag information 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.

	   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

       Return Value:
	   True on success.

       Sample XMP 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

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