Bookmark URL Parsing

[Timothy Wu]

Hi,

I'm trying to parse FireFox bookmark files manually using regular
expressions. I tried to match key-value pairs in tags like the following:

  matches = re.findall(r'(\S+)="(.+)"', text)

However, I find that if the URL I'm matching contains something
non-standard I may encounter a problem. For example, one of the link
content I have is javascript code and contains character %22(as shown
when opening with VI). I've figure out that %22 equals to the quotation
mark '"'. That interferes with my match.

How exactly does %22 maps to the quotation mark? I know I often see the
kind of representation in a URL, but what exactly is it and where would
I find info on that? And most importantly, how do I make my match work?
