[jdom-interest] Parsing HTML elements

[Rolf Lear]

Hi Paul.

In the mail below I suggested using a parsing proxy. The term I meant to 
use is a 'Filter'. See this article here:

http://www.ibm.com/developerworks/xml/library/x-tipsaxfilter/

You can do some magic with 
http://www.jdom.org/docs/apidocs/org/jdom2/input/SAXBuilder.html#setXMLFilter(org.xml.sax.XMLFilter)

For example, your filter could exend 
http://docs.oracle.com/javase/6/docs/api/org/xml/sax/helpers/XMLFilterImpl.html

and then override the method 
http://docs.oracle.com/javase/6/docs/api/org/xml/sax/helpers/XMLFilterImpl.html#startElement(java.lang.String,%20java.lang.String,%20java.lang.String,%20org.xml.sax.Attributes)

to set the 'attrs' URI's correctly, and then call super.startElement(....).
