Support nested tags for XMLLoader
---------------------------------
Key: PIG-2147
URL: https://issues.apache.org/jira/browse/PIG-2147
Project: Pig
Issue Type: Bug
Affects Versions: 0.8.1, 0.9.0
Reporter: Vivek Padmanabhan
Assignee: Vivek Padmanabhan
Currently xmlloader does not support nested tags with same tag name, ie if i
have the below content
{code}
<event>
<relatedEvents>
<event>x<\event>
<event>y<\event>
<event>z<\event>
<\relatedEvents>
<\event>
{code}
And I load the above using XMLLoader,
events = load 'input' using org.apache.pig.piggybank.storage.XMLLoader('event')
as (doc:chararray);
The output will be,
{code}
<event>
<relatedEvents>
<event>x<\event>
{code}
Whereas the desired output is ;
{code}
<relatedEvents>
<event>x<\event>
<event>y<\event>
<event>z<\event>
<\relatedEvents>
{code}
