nodelist(3)
NAME
XML::DOM::NodeList - A node list as used by XML::DOM
DESCRIPTION
The NodeList interface provides the abstraction of an
ordered collection of nodes, without defining or con
straining how this collection is implemented.
The items in the NodeList are accessible via an integral
index, starting from 0.
Although the DOM spec states that all NodeLists are "live"
in that they allways reflect changes to the DOM tree, the
NodeList returned by getElementsByTagName is not live in
this implementation. See CAVEATS for details.
METHODS
- item (index)
- Returns the indexth item in the collection. If index
is greater than or equal to the number of nodes in the
list, this returns undef. - getLength
- The number of nodes in the list. The range of valid
child node indices is 0 to length-1 inclusive. - Additional methods not in the DOM Spec
- dispose
- Removes all circular references in this NodeList and
its descendants so the objects can be claimed for
garbage collection. The objects should not be used
afterwards.
