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 template file (be it 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.
