I'm writing a code that should extract tags from an HTML code (I'm skipping parts about parsing and stuff). I'm testing it using a simple fixed string however, it doesn't remove this <div> tag and I have no idea why...

Thanks...

import re

RegExpression_Tags = r"<.*?>"

html = """
<div style="background: url(/groups/roundedcorners?
c=999999&bc=white&w=4&h=4&a=af) 0px 0px; width: 4px; height: 4px">
Ask how to use HTMLParser
</div>"""

p = re.compile(r"<.*?>")
NoTags = p.sub( '' , html)
print NoTags

This?

^<([a-z]+)([^<]+)*(?:>(.*)<\/\1>|\s+\/>)$

Thank you but it didn't work :confused:

When comes html regex may not be the right tool.
Look into beautifulsoup and lxml.

Read this answer by bobince about regex/html,one of the best answer i have read and funny to.

Here is one way.

import re

html = """\
<div style="background: url(/groups/roundedcorners?
c=999999&bc=white&w=4&h=4&a=af) 0px 0px; width: 4px; height: 4px">
Ask how to use HTMLParser
</div>"""

test_match = re.sub(r'<.*?>|<\w{3}', '', html)
print test_match 

'''-->Out
 style="background: url(/groups/roundedcorners?
c=999999&bc=white&w=4&h=4&a=af) 0px 0px; width: 4px; height: 4px">
Ask how to use HTMLParser
'''

thanks snippsat.
Actually, I am using BeautifulSoup for parsing the html pages. I tried traversing the parsed trees until i reach the leaves i.e. the NavigableStrings and extract these. This sounds like the best thing to do but didn't work :( I didn't find enough examples for NavigableStrings. That's why I went to option 2 which is RegEx.
