Parsing an InputStream or passing an InputStream into an XSLT processor is no big deal; in the XSLT case:

javax.xml.transform.stream.StreamSource ss = new javax.xml.transform.stream.StreamSource(<<your input stream here>>);

Here is one approach:

1) Wrap your InputStream in a StreamSource as above.
2) Write an XSLT stylesheet that converts the input XML document into a set of SQL statements (e.g., an INSERT statement).
3) Create a StreamResult that wraps a StringWriter.
4) Run the transformation against the StreamSource.
5) Collect the resulting SQL from the StringWriter and execute it against the target database.

Other approaches include writing your own SAX handler, but the XSLT approach is the simplest (and most appropriate to the list).
