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 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.

NAME

       XML::XPathEngine::NodeSet - a list of XML document nodes

DESCRIPTION

       An XML::XPathEngine::NodeSet object contains an ordered list of nodes. The nodes each take the same format as described in
       XML::XPathEngine::XMLParser.

SYNOPSIS

	       my $results = $xp->find('//someelement');
	       if (!$results->isa('XML::XPathEngine::NodeSet')) {
		       print "Found $results
";
		       exit;
	       }
	       foreach my $context ($results->get_nodelist) {
		       my $newresults = $xp->find('./other/element', $context);
		       ...
	       }

API

   new()
       You will almost never have to create a new NodeSet object, as it is all done for you by XPath.

   get_nodelist()
       Returns a list of nodes. See XML::XPathEngine::XMLParser for the format of the nodes.

   string_value()
       Returns the string-value of the first node in the list.	See the XPath specification for what "string-value" means.

   string_values()
       Returns a list of the string-values of all the nodes in the list.

   to_literal()
       Returns the concatenation of all the string-values of all the nodes in the list.

   get_node($pos)
       Returns the node at $pos. The node position in XPath is based at 1, not 0.

   size()
       Returns the number of nodes in the NodeSet.

   pop()
       Equivalent to perl's pop function.

   push(@nodes)
       Equivalent to perl's push function.

   append($nodeset)
       Given a nodeset, appends the list of nodes in $nodeset to the end of the current list.

   shift()
       Equivalent to perl's shift function.

   unshift(@nodes)
       Equivalent to perl's unshift function.

   prepend($nodeset)
       Given a nodeset, prepends the list of nodes in $nodeset to the front of the current list.
