[xsl] create xml from incoming xml and load it into a variable

[sudheshna iyer <sudheshnaiyer@xxxxxxxxx>]

How do I create xml from incoming xml and load it into a variable from xsl? Afterr loading I 

have to loop through the variable for doing more xsl transformations?

My xsl has incoming xml. I have to create another xml of different format, put it in a variable
and loop through that variable to apply more xsl transformations.
