An XML::LibXML::NodeList object contains an ordered list of nodes, as detailed by the W3C DOM documentation of Node Lists.SYNOPSIS

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, the contents of the node list, as a perl list.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 $pos. The node position in XPath is based at 1, not 0.size()
Returns the number of nodes in the NodeSet.pop()
Equivalent to perl's pop function.push(@nodes)
Equivalent to perl's push function.append($nodelist)
Given a nodelist, appends the list of nodes in $nodelist to the end of the current list.shift()
Equivalent to perl's shift function.unshift(@nodes)
Equivalent to perl's unshift function.prepend($nodeset)
Given a nodelist, prepends the list of nodes in $nodelist to the front of the current list.iterator()
Will return a new nodelist iterator for the current nodelist. A nodelist iterator is usefull if more complex nodelist processing is needed.Contenus ©2006-2024 Benjamin Poulain
