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

In XPath terms a Literal is what we know as a 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"

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

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