Char::Class::XML

XML-related character classes such as InXML_NameStartChar10 (XML 1.0 name start characters) and InXMLNameChar (XML 1.1 name characters).

A module for normalization:

Char::Normalize::FullwidthHalfwidth (New in 2.0)

Install

1. Download the tarball and extract it.
2. perl Makefile.PL
3. make
4. make install

Alternatively, just putting all files in the directory lib into your directory for Perl modules should work as well. All Perl modules in this package are written in pure Perl.

Example

use Char::Class::XML qw/InXML_NameStartChar10 InXMLNameChar10/;

if ($name !~ /\A\p{InXML_NameStartChar10}\p{InXMLNameChar10}*\z/) {
  die "$0: $name: This is not an XML 1.0 Name";
}

Distribution

Snapshot release versions are available as follows:

• CharClass Latest Stable Release (tar + gzip)
• CharClass Version 1.0, July 19, 2007 (tar + gzip, 244ko)

$ git clone http://suika.fam.cx/gate/git/bare/charclass.git/

TODO

• Some classes are no longer up-to-date. Need to update.
• Need to improve documentation.

Note that there is a bug tracking system.
