XML::Validator::Schema version 1.10
CHANGES
- Added a check in Makefile.PL for a broken XML::SAX install.
Hopefully this will convince the legions of CPAN testers with
broken XML::SAX installs to leave me alone.
DESCRIPTION
This module allows you to validate XML documents against a W3C XML
Schema. This module does not implement the full W3C XML Schema
recommendation (http://www.w3.org/XML/Schema), but a useful subset. See
the SCHEMA SUPPORT section in the module documention.
IMPORTANT NOTE: To get line and column numbers in the error
messages generated by this module you must install
XML::Filter::ExceptionLocator and use XML::SAX::ExpatXS as your
SAX parser. This module is much more useful if you can tell where
your errors are, so using these modules is highly recommeded!
RATIONALE
I'm writing a piece of software which uses Xerces/C++ (
http://xml.apache.org/xerces-c/ ) to validate documents against XML
Schema schemas. This works very well, but I'd like to release my project
to the world. Requiring users to install Xerces is simply too onerous a
requirement; few will have it already and the Xerces installation system
leaves much to be desired.
On CPAN, the only available XML Schema validator is XML::Schema.
Unfortunately, this module isn't ready for use as it lacks the ability
to actually parse the XML Schema document format! I looked into
enhancing XML::Schema but I must admit that I'm not smart enough to
understand the code... One day, when XML::Schema is completed I will
replace this module with a wrapper around it.
This module represents my attempt to support enough XML Schema syntax to
be useful without attempting to tackle the full standard. I'm sure this
will mean that it can't be used in all situations, but hopefully that
won't prevent it from being used at all.
INSTALLATION
The easiest way to install this module is using CPAN.pm:
perl -MCPAN -e 'install XML::Validator::Schema'
If you must do it the old-fashioned way, first install:
Carp
Test::More
XML::SAX
Tree::DAG_Node
XML::Filter::BufferText
Then unpack this module's distribution and do:
perl Makefile.PL
make test
make install
