XML::LibXML::Literal − Simple string values.
In XPath terms a Literal is what we know as a string.
new($string)
Create a new Literal object with the value in $string. Note
that " and ' will be converted to "
and ’ respectively. That is not part of the XPath
specification, but I consider it useful. Note though that
you have to go to extraordinary lengths in an
XML template file (be it XSLT
or whatever) to make use of this:
<xsl:value−of select=""I'm feeling &quot;sad&quot;""/>
Which produces a Literal of:
I'm feeling "sad"
value()
Also overloaded as stringification, simply returns the
literal string value.
cmp($literal)
Returns the equivalent of perl’s cmp operator against
the given $literal.
