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.
