[xml] direct Api to obtain specific child node

["Prashanth R" <ramapra gmail com>]

Is there a direct API ( without me writing code to iterate over xmlnodePtr objects to find a node with a specific name )

Consider this example 

<top>

   <elementA></elementA>

  <elementB></elementB>

  <elementZ></elementZ>

</top>

Say I have an xmlNodePtr instance that corresponds to the element - <top> 

Now is there a directway of obtaining a ElementZ

Is there an API like this

xmlNodePtr GetChildNodePtr(xmlNodePtr top, const char *childName)

that will return me a reference to element Z 

Do i have to iterate thru elements to decide if there is a match ?
