NAME¶
XML::XPath::NodeSet - a list of XML document nodes
DESCRIPTION¶
An XML::XPath::NodeSet object contains an ordered list of nodes. The nodes each take the same format as described in XML::XPath::XMLParser.
SYNOPSIS¶
my $results = $xp->find('//someelement'); if (!$results->isa('XML::XPath::NodeSet')) { print "Found $results\n"; exit; } foreach my $context ($results->get_nodelist) { my $newresults = $xp->find('./other/element', $context); ... }
API¶
new()¶
You will almost never have to create a new NodeSet object, as it is all done for you by XPath.
get_nodelist()¶
Returns a list of nodes. See XML::XPath::XMLParser for the format of the nodes.
string_value()¶
Returns the string-value of the first node in the list. See the XPath specification for what "string-value" means.
to_literal()¶
Returns the concatenation of all the string-values of all the nodes in the list.
get_node($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.
