.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The Template-XML distribution provides a number of Template Toolkit
plugin modules for working with \s-1XML\s0.
.PP
The Template::Plugin::XML module is a front-end to the various other
\&\s-1XML\s0 plugin modules.  Through this you can access \s-1XML\s0 files and
directories of \s-1XML\s0 files via the Template::Plugin::XML::File and
Template::Plugin::XML::Directory modules (which subclass from the
Template::Plugin::File and Template::Plugin::Directory modules
respectively).  You can then create a Document Object Model (\s-1DOM\s0) from
an \s-1XML\s0 file (Template::Plugin::XML::DOM), examine it using XPath
queries (Template::Plugin::XML::XPath), turn it into a Perl data
structure (Template::Plugin::XML::Simple) or parse it as an \s-1RSS\s0 (\s-1RDF\s0
Site Summary) file.
.PP
The basic \s-1XML\s0 plugins were distributed as part of the Template Toolkit
until version 2.15 released in May 2006.  At this time they were
extracted into this separate Template-XML distribution and an alpha
version of this Template::Plugin::XML front-end module was added.
.PP
The Template::Plugin::XML module is still in development and not
guaranteed to work correctly yet.  However, all the other \s-1XML\s0 plugins
are more-or-less exactly as they were in \s-1TT\s0 version 2.14 and should
work as normal.
.PP
For general information on the Template Toolkit see the documentation
for the Template module or <http://template\-toolkit.org>.  For
information on using plugins, see Template::Plugins and
\&\*(L"\s-1USE\s0\*(R" in Template::Manual::Directives.  For further information
on \s-1XML\s0, see <http://xml.com/>.
.SH "METHODS"
.IX Header "METHODS"
The \s-1XML\s0 plugin module provides a number of methods to create various
other \s-1XML\s0 plugin objects.
.Sh "file(name)"
.IX Subsection "file(name)"
Creates a Template::Plugin::XML::File object.  This is a subclass
of Template::Plugin::File.
.Sh "dir(path)"
.IX Subsection "dir(path)"
Creates a Template::Plugin::XML::Directory object.  This is a subclass
of Template::Plugin::Directory.
.Sh "\fIdom()\fP"
.IX Subsection "dom()"
Generate a Document Object Module from an \s-1XML\s0 file.  This can be
called against a directory, file or an \s-1XML\s0 plugin object, as long as
the source \s-1XML\s0 filename is defined somewhere along the line.
.PP
.Vb 1
\&    [% dom = XML.dom(filename) %]
.Ve
.PP
.Vb 3
\&    [% file = XML.file(filename);
\&       dom  = file.dom
\&    %]
.Ve
.PP
.Vb 3
\&    [% dir = XML.dir(dirname);
\&       dom = dir.dom(filename)
\&    %]
.Ve
.Sh "\fIxpath()\fP"
.IX Subsection "xpath()"
Perform XPath queries on the file.  Like the \fIdom()\fR method, \fIxpath()\fR can
be called against a file, directory or an \s-1XML\s0 plugin object.
.PP
.Vb 1
\&    [% xpath = XML.xpath(filename) %]

\&\s-1TODO:\s0 As per \fIdom()\fR and \fIxpath()\fR but for XML::Simple
.Sh "\fIrss()\fP"
.IX Subsection "rss()"
\&\s-1TODO:\s0 As per \fIdom()\fR, \fIxpath()\fR and \fIsimple()\fR but for \s-1XML::RSS\s0
.SH "XML PLUGINS"
.IX Header "XML PLUGINS"
These are the \s-1XML\s0 plugins provided in this distribution.  
.Sh "Template::Plugin::XML"
.IX Subsection "Template::Plugin::XML"
Front-end module to the \s-1XML\s0 plugin collection.
.Sh "Template::Plugin::XML::File"
.IX Subsection "Template::Plugin::XML::File"
This plugin module is used to represent individual \s-1XML\s0 files.  It is a
subclass of the Template::Plugin::File module, providing the
additional \fIdom()\fR, \fIxpath()\fR, \fIsimple()\fR and other methods relevant to \s-1XML\s0
files.
.Sh "Template::Plugin::XML::Directory"
.IX Subsection "Template::Plugin::XML::Directory"
This plugin module is used to represent directories of \s-1XML\s0 files.  It
is a subclass of the Template::Plugin::Directory module and provides
the same additional \s-1XML\s0 related methods as Template::Plugin::XML::File.
.Sh "Template::Plugin::XML::DOM"
.IX Subsection "Template::Plugin::XML::DOM"
Plugin interface providing access to the \s-1XML::DOM\s0 module.
.PP
.Vb 3
\&    [% USE XD = XML.Dom %]
\&    [% dom = XD.parse_file(\(aqexample.xml\(aq) %]
\&    [% pages = dom.getElementsByTagName(\(aqpage\(aq) %]
.Ve
.Sh "Template::Plugin::XML::RSS"
.IX Subsection "Template::Plugin::XML::RSS"
Plugin interface providing access to the \s-1XML::RSS\s0 module.
.PP
.Vb 4
\&    [% USE news = XML.RSS(\(aqnews.rdf\(aq) \-%]
\&    [% FOREACH item IN news.items \-%]
\&       * [% item.title %]
\&    [% END %]
.Ve
.Sh "Template::Plugin::XML::Simple"
.IX Subsection "Template::Plugin::XML::Simple"
Plugin interface providing access to the XML::Simple module.
.PP
.Vb 1
\&    [%  USE xml = XML.Simple(\(aqexample.xml\(aq) %]
.Ve
.Sh "Template::Plugin::XML::XPath"
.IX Subsection "Template::Plugin::XML::XPath"
Plugin interface providing access to the XML::XPath module.
.PP
.Vb 3
\&    [% USE xpath = XML.XPath(\(aqexample.xml\(aq);
\&       bar = xpath.find(\(aq/foo/bar\(aq);
\&    %]
