Re: What's the best way to write this regular expression?

After a bit of reading, I've decided to use Beautiful Soup 4, with lxml as the parser. I considered simply using lxml to do all the work, but I just got lost in the documentation and tutorials. I couldn't find a clear explanation of how to parse an HTML file and then navigate its structure. The Be

Hi, I am confused between plain python, numpy, scipy, pylab, matplotlib. I have high familiarity with matlab, but the computer I use does not have it. So moving to python. What should I use? and the best way to use it. I will be running matlab-like scripts sometimes on the shell prompt and someti

Hi Peter, A related question. Is there anyhing like a built in signature which would help to detect, that one tries to unpickle an object whose byte code has changed? The idea is to distinguish old and new pickled data and start some 'migration code' fi required The only thing, that I thought

Re: What's the best way to write this regular expression?

Thanks. I'm thinking the choice might be between lxml and Beautiful Soup, but since BS uses lxml as a parser, I'm trying to figure out the difference between them. I don't necessarily need the simplest (html.parser), but I want to choose one that is simple enough yet powerful enough that I won't ha
