Interface Element : Methods getElementsByTagName or getElementsByTagNameNS if you're using namespaces.

I don't think there is  method to do this in one step. I would use

Node.getChildNodes()  and then loop on the result to find node of type
Element_node with the right tag.

The interface Document implements the methods getElementsByTagName or
      getElementsByTagNameNS. Then you could explore the result to find the
      node matching your criterias.
