* Parse a well-balanced chunk of an XML document

* The allowed sequence for the Well Balanced Chunk is the one defined by
* the content production in the XML grammar:

* Returns 0 if the chunk is well balanced, -1 in case of args problem and
* the parser error code otherwise
*
* In case recover is set to 1, the nodelist will not be empty even if
* the parsed chunk is not well balanced.
