Alan Ho commented on HADOOP-2439:
---------------------------------
The approach described doesn't use a StaX parser, and probably isn't going to
be as robust to failure or as extensible as using a StaX parser. If you look at
the code, my patch allows you to specify the XML element name,
"namespace_prefix", and namespace_URI when identifying the correct tag. My
patch also makes it easier to massage the XML too when reading in data.
Initially when I tried to create a XML parser, I tried to hack something up
like the previous approach described. But after trying to parse real-world data
(e.g. a dump of wikipedia), I threw up my arms and decided to use a proper
pull-parser.

> Hadoop does not have a good XML parser for XML input. The XML parser in the
