and to be more clear, I have a folder with multiple xml files thatI want to
read and parse in order to extract some attributes (att1,att2) values ....

UnifLines = load '$unif_xml'
using org.apache.pig.piggybank.storage.XMLLoader('REC')
as (doc:chararray);
UnifXmlByDocId = stream UnifLines through analyze_unif
as (docid : int,
xml_comp: chararray
);

where analyze_unif_recs.py is a python script I wrote that does the xml
parsing, and org.apache.pig.piggybank.storage.XMLLoader('REC') finds the
<REC> elements in the xml input, that are passed to my script.
