.SH "NAME"
XML::DOM::NodeList \- A node list as used by XML::DOM
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The NodeList interface provides the abstraction of an ordered
collection of nodes, without defining or constraining how this
collection is implemented.
.PP
The items in the NodeList are accessible via an integral index,
starting from 0.
.PP
Although the \s-1DOM\s0 spec states that all NodeLists are \*(L"live\*(R" in that they
always reflect changes to the \s-1DOM\s0 tree, the NodeList returned by
getElementsByTagName is not live in this implementation. See \s-1CAVEATS\s0
for details.
.SS "\s-1METHODS\s0"
.IX Subsection "METHODS"
.IP "item (index)" 4
.IX Item "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.
.IP "getLength" 4
.IX Item "getLength"
The number of nodes in the list. The range of valid child
node indices is 0 to length\-1 inclusive.
.SS "Additional methods not in the \s-1DOM\s0 Spec"
.IX Subsection "Additional methods not in the DOM Spec"
.IP "dispose" 4
.IX Item "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.
