I think he just wants to make sure the HTML is well-formed, not strip
the tags completely. However, strip_tags() is something WebHelpers
should provide. I've noticed the lack a couple times. However, I'm
not sure of the best implementation.
- sgmllib: (used in cleanhtml.py): not in Python 3. Can
cleanhtml.py be ported to HTMLParser?
- lxml: hard to install on Mac and Windows due to C dependencies.
- BeautifulSoup: has the best ability to parse real-world (i.e.,
misformed) HTML. However, it's a largish library so I'm not sure any
helper should depend on it.
- Simplicity vs speed. Would routines that depend only on the
Python standard library be fast enough?
As for Matt's case of truncating HTML without making it misformed,
would this be widely enough used to justify making a webhelper for it?
