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=""I'm feeling &quot;sad&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
