Are you sure you are processing text rather than structured data? HTML
doesn't have the notion of a "line". To extract information from HTML tools
like Beautiful Soup are better suited than regular expressions:
import bs4
import re
s = ...
soup = bs4.BeautifulSoup(s)
for a in soup.find_all("a", id=re.compile(r"Course\S+\|\S+\|")):
print a["id"]
print a.text
print a.parent.parent["colspan"]
