suggestions on extending any23 - get context of triples

Hi all

We have a special need in our work that we need to not only extract 
triples from a page, but also knowining the contexts of the triples. By 
context I mean the html elements containing the Subject or Object of the 
triple, and the xpath to it. For example, on this page 
http://www.imdb.com/title/tt0071562/, let's suppose a triple "_:nodexyz 
<rdfs:type> http://schema.org/Movie" and "_:nodexyz 
<schema.org/itemprop/actors> Al Pacino".

I would like to be able to know that "al pacino" is in an html element 
that has this xpath: <html><body><blahblah><div class="txt-block"><a>

Can you give some general suggestions on which classes I should 
extend/starting point?

Many thanks!

Hi Ziqi,

Have you checked out the XPath extractor suite[0] in the extractor
package? I've not used this but it looks bang on what you are after.
