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.
