I think a more robust way to go about this would be:

(1) Use os.walk to walk through the directory
   http://docs.python.org/lib/os-file-dir.html

(2) Use Beautiful Soup to extract the internal links from each file
   http://crummy.com/software/BeautifulSoup/documentation.html

from BeautifulSoup import BeautifulSoup

soup = BeautifulSoup(doc)
links = soup('a')
internal_links = [link["href"]
                        for link in links
                        if link.has_key("href") and not
link["href"].startswith("http")]

(4) Do straight string replacements on those links (no regex needed)

(5) Save each html file to *.html.bak before changing
