NAME
       XML::XPathEngine::Literal - Simple string values.

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

API
   new($string)
       Create a new Literal object with the value in $string. Note that " and ' 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"

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

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