XML::XPath::NodeSet - phpMan

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.
