I want a regex which can match conditional comments in a HTML source page so I can remove only those. I want to preserve the regular comments.
I would also like to avoid using the .*? notation if possible.
The text is
foo
<!--[if IE]>
<style type="text/css">
ul.menu ul li{
font-size: 10px;
font-weight:normal;
padding-top:0px;
}
</style>
<![endif]-->
bar
and I want to remove everything in <!--[if IE]> and <![endif]-->
EDIT: It is because of BeautifulSoup I want to remove these tags. BeautifulSoup fails to parse and gives an incomplete source
EDIT2: [if IE] isn't the only condition. There are lots more and I don't have any list of all possible combinations.
EDIT3: Vinko Vrsalovic's solution works, but the actual problem why beautifulsoup failed was because of a rogue comment within the conditional comment. Like
<!--[if lt IE 7.]>
<script defer type="text/javascript" src="pngfix_253168.js"></script><!--png fix for IE-->
<![endif]-->
Notice the <!--png fix for IE--> comment?
Though my problem was solve, I would love to get a regex solution for this.

>>> from BeautifulSoup import BeautifulSoup, Comment
>>> html = '<html><!--[if IE]> bloo blee<![endif]--></html>'
>>> soup = BeautifulSoup(html)
>>> comments = soup.findAll(text=lambda text:isinstance(text, Comment)
and text.find('if') != -1) #This is one line, of course
>>> [comment.extract() for comment in comments]
[u'[if IE]> bloo blee<![endif]']
>>> print soup.prettify()
<html>
</html>
>>>
python 3 with bf4:
from bs4 import BeautifulSoup, Comment
html = '<html><!--[if IE]> bloo blee<![endif]--></html>'
soup = BeautifulSoup(html, "html.parser")
comments = soup.findAll(text=lambda text:isinstance(text, Comment)
and text.find('if') != -1) #This is one line, of course
[comment.extract() for comment in comments]
[u'[if IE]> bloo blee<![endif]']
print (soup.prettify())
If your data gets BeautifulSoup confused, you can fix it before hand or customize the parser, among other solutions.
EDIT: Per your comment, you just modify the lambda passed to findAll as you need (I modified it)
