NAME

6       Image::ExifTool::TagInfoXML - Read/write tag information XML database
7

DESCRIPTION

9       This module is used to generate an XML database from all ExifTool tag
10       information.  The XML database may then be edited and used to re-
11       generate the language modules (Image::ExifTool::Lang::*).
12

15       Print complete tag information database in XML format.

21         Image::ExifTool::TagInfoXML::Write(undef, 'IPTC', Flags => 1);

30           1) [optional] String of group names separated by colons to specify
31           the group to print.  A specific IFD may not be given as a group,

47         <taginfo>
48
49         <table name='XMP::dc' g0='XMP' g1='XMP-dc' g2='Other'>
50          <desc lang='en'>XMP Dublin Core</desc>
