XML::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 &quot; and &apos; 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.
