Push a contentHandler and maybe continue parsing...

Push a contentHadler on the content handler stack. If there are currently no other handlers on the stack that is all that happens.

If there are other content handlers on the stack it is assumed that a XML file is being processed and processing continues by calling startElement() of the newly pushed handler. In this case pushContentHandler() will not return until the element has been fully processed.
