Python provides HTML parsing through the
HTMLParser and htmllib modules.
For my application, I needed to search through
an HTML document in a nonlinear fashion and
dynamically change parts of the document. The
most logical way to do this is to translate HTML
back and forth to a data structure.
I wrote a module called htmldata, available from:
http://oregonstate.edu/~barnesc/htmldata/
Example:
from htmldata import dumps, loads
o=loads('<img src=hi.gif alt="blah">foo</body>')
o [('img', {'src':'hi.gif', 'alt':'blah'}), 'foo',
('/body', {})] dumps(o)
'<img alt="blah" src="hi.gif">foo</body>'
Pros:
* More powerful for HTML editing.
* Easy to reproduce the original document (at least,
a document that is HTML-equiv to the original).
Cons:
* Less user friendly than HTMLParser module.
I tested it on several popular sites. Feedback, bug
reports, etc appreciated.
