I've used BeautifulSoup in the past but after a while I realised I didn't have a use case for HTML parsing. Either I was using a scraping library or something like mechanize to hack things about or it was me generating the HTML, in which case I shouldn't need to re-parse it anyway.
I've only used BeautifulSoup, and have found it to be fast enough for the simple scripts I need to write. Its documentation is excellent. I'd suggest starting out using it and if performance does become a hinderance, look elsewhere at that point.
Hello,
I'm using BS to parse HTML themes, usually with 4/5 pages.
All related operations (page load, update properties on nodes, extract components) are executed in a few seconds, I never felt that perf is an issue with this small amount of input. Using a large amount of input data, maybe lxml can perform better.
On top of that, BS support lxml as plugin parser (along with html.parser ).
I'm biased in favour of BeautifulSoup, because the majority of the html and xml I've come across is not well-formed. In my experience BeautifulSoup is much more forgiving.
I've made use of it in
github.com/jmcp/grabbag/blob/maste...
and
github.com/jmcp/grabbag/blob/maste...
and in another minor project I'm working over at the moment where I'm taking KML and ogr2ogr-converted Mapinfo shape files which will find its way to the grabbag in due course.
I'm not particularly stressed about the performance of the solution, btw, so long as I have written efficient code I'm not worried about the library I'm using.
I'm a fan of lxml but I haven't done any HTML parsing in a while. lxml is written in C and BeautifulSoup in Python IIRC, which tends to be slower than C.
I think your best bet is to write a pet project, feed the same HTML to both, measure performance but also see if they behave the same way. Different parsers sometimes have different behaviors in corner cases or malformed input.
Yes, I do.
I use lxml to parsing HTML. :)
