Hey Brian,
It seems the text you are trying to parse is similar to XML/HTML.
So I'd use BeautifulSoup[1] if I were you :)
here's a sample code for your scraping case:
from BeautifulSoup import BeautifulSoup
<python>
# assume the s variable has your text
s = "whatever xml or html here"
# turn it into a tasty & parsable soup :)
soup = BeautifulSoup(s)
# for every element tag in the soup
for el in soup.findAll("element"):
# print out its tag & name attribute plus its inner value!
print el["tag"], el["name"], el.string
</python>
that's it!
