my bad, it looks like XPathEntityProcessor doesn't support relative xpaths.
However, I quickly looked at the Slashdot example (which is pretty good actually) at http://wiki.apache.org/solr/DataImportHandler. >From that I infer that you use only 1 entity per xml-doc. And within that entity use multiple field declararations with xpath-attributes to extract the values you want. So even though your xml-dcoument is nested (like most xml's are) your field-declarations are not. I think your best bet is to read the slashdot example and go from there. For now, I'm not entirely sure what you want a solr-document to be in your example. i.e: - 1 solr-document per 1 xml-document (as supplied) - or 1 solr-doc per CHAP per PARA or per SUB? Once you know that, perhaps coming up with a decent pointer is easier.
