Strange list problem

[Gustaf Liljegren]

Sorry for that bad subject; it's hard to describe this problem. I get list 
items instead of strings from the following operation:

  # Extract links for web pages
  def getLinksHTML(self):
    if self.refs:
      ...
      for a in self.refs:
        print a

So 'a' here returns values like ['http://www.python.org'] instead of normal 
strings. I know this isn't the normal behavior, but I don't know what might 
cause it. Any ideas?

Since I need to change case here, I had to make the following work-around:

        a = str(a)
        a = a.lower()

But it would be better to get strings in the first place of course.
