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.
