XPath::Literal(3)                    User Contributed Perl Documentation                   XPath::Literal(3)



NAME
       XML::XPath::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.
