Subject Re: Which is a good XPath generator?
Date Sun, 25 Jul 2010 12:31:43 GMT
I am assuming (like Li I think)  that you want to induce a structure/schema
from a html-example so you can use that schema to extract data from similiar
html-structured pages.

Another term often used in literature for that is "Wrapper Induction".
Beside DOM, using CSS-classes often give good distinction and they are often
more stable under small redesigns.

Besides Li's suggestions have a look at this thread for an open source
python implementation (I hav enever tested it)
http://www.holovaty.com/writing/templatemaker/
also make sure to read all the comments for links to other products, etc.

HTH,
Geert-Jan
