     2 

     3 XML::DOM::NodeList - A node list as used by XML::DOM

     4 

     5 =head1 DESCRIPTION

     6 

     7 The NodeList interface provides the abstraction of an ordered

     8 collection of nodes, without defining or constraining how this

     9 collection is implemented.

    10 

    11 The items in the NodeList are accessible via an integral index,

    12 starting from 0.

    13 

    14 Although the DOM spec states that all NodeLists are "live" in that they

    15 allways reflect changes to the DOM tree, the NodeList returned by

    16 getElementsByTagName is not live in this implementation. See L<CAVEATS>

    17 for details.

    23 =item item (index)

    24 

    25 Returns the indexth item in the collection. If index is

    26 greater than or equal to the number of nodes in the list,

    27 this returns undef.

    28 

    29 =item getLength

    30 

    31 The number of nodes in the list. The range of valid child

    32 node indices is 0 to length-1 inclusive.

    39 

    40 =item dispose

    41 

    42 Removes all circular references in this NodeList and its descendants so the 

    43 objects can be claimed for garbage collection. The objects should not be used

    44 afterwards.
