XML::XPathEngine::Literal \- Simple string values.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
In XPath terms a Literal is what we know as a string.
.SH "API"
.IX Header "API"
.SS "new($string)"
.IX Subsection "new($string)"
Create a new Literal object with the value in \f(CW$string\fR. Note that &quot; and
&apos; will be converted to " and ' respectively. That is not part of the XPath
specification, but I consider it useful. Note though that you have to go
to extraordinary lengths in an \s-1XML\s0 template file (be it \s-1XSLT\s0 or whatever) to
make use of this:
.PP
.Vb 1
\&        <xsl:value\-of select="&quot;I\*(Aqm feeling &amp;quot;sad&amp;quot;&quot;"/>
.Ve
.PP
Which produces a Literal of:
.PP
.Vb 1
\&        I\*(Aqm feeling "sad"
.Ve
.SS "\fIvalue()\fP"
.IX Subsection "value()"
Also overloaded as stringification, simply returns the literal string value.
.SS "cmp($literal)"
.IX Subsection "cmp($literal)"
Returns the equivalent of perl's cmp operator against the given \f(CW$literal\fR.
