I'm not sure what exactly the question is here, but: Parse your XML document and for each

element you encounter create a new Document instance, and then populate its fields with some data, like the URI data you mentioned. If you parse with DOM - just walk the node tree and make new Document whenever you encounter an element you want as a separate Document. If you are using the SAX API you'll probably want some logic in start/endElement and characters methods. When you reach the end of the element you are done with your Document instance, so add it to the IndexWriter instance that you opened once, before the parser. When you are done with the whole XML document close the IndexWriter.
