> Piggybank: XPath cant handle namespace in xpath, nor can it return more than
> one match

> If you pass an xpath that contains a namespace the XPath UDF will always fail
> to match.
> It would be better to either silently remove the namespace or provide a
> parameter that will remove it.
> The reason it is desirable to ignore xpath's with namespaces is that many xml
> tools when selecting an xpath provide the namespace. It makes cutting &
> pasting into a pig script painful if you need to manually remove it.
> Additionally XPath only returns the *first* match. It is often desirable to
> return all matches and allow for a flattening to process multiple records.
> An XPathAll would be useful to have.
> A patch is available as a git pullrequest at
> https://github.com/apache/pig/pull/14
