Tree::XPathEngine::Literal - Simple string values.

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.

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

   OtherMethods
       Those are needed so the objects can be properly processed in various contexts

       as_string
       as_xml
       value
       evaluate
       xpath_to_boolean
       xpath_to_literal

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