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.
