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 constraining 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.
