I have some HTML content where there are many links as the following pattern:

I want to filter all the links into a list as:
['http://example.com/2013/01/problem1.html',
'http://example.com/2013/02/problem2.html']
How to do it using Python Regular Expression?
You can try, but regular expressions are not a reliable way
to parse HTML.
You are much better to use a dedicated HTML parser such
as the one found in htmllib in the standard library or
a third party tool like BeautifulSoup.
These recognise the different tag types and separate the content
and data for you. You can then just ask for the parser to
find <a...> tags and then fetch the data from each tag.
