Indexing fields of xml file using solrj

[Radha C.]

Hi All,
 
I want to index the document fields in a xml file to index using solrj. I
know how to index the document fields using doc.addfield(). But I dont know
how to post the xml document instead of adding each field in solrj. 
 
Can I index xml file using solrj? Can anyone help me in how to do this? 
 
Thanks,
