=head1 NAME

XML::LibXML::Literal - Simple string values.

=head1 DESCRIPTION

In XPath terms a Literal is what we know as a string.

=head1 API

=head2 new($string)

Create a new Literal object with the value in $string. Note that &quot; and
&apos; will be converted to " and ' respectively. That is not part of the XPath
specification, but I consider it useful. Note though that you have to go
to extraordinary lengths in an XML template file (be it XSLT or whatever) to
make use of this:

<xsl:value-of select="&quot;I'm feeling &amp;quot;sad&amp;quot;&quot;"/>

Which produces a Literal of:

I'm feeling "sad"

=head2 value()

Also overloaded as stringification, simply returns the literal string value.

=head2 cmp($literal)

Returns the equivalent of perl's cmp operator against the given $literal.

=cut
