Was the string methods solution that I gave a week or so ago so bad that
you still think that you need a regex to solve this?

My Apology Mark. You took the time to give me the basis of a non-regex
solution and I had not taken the time to fully review your answer.Did not
understand it at first blush, but I think now I do.
Accepted :)
IIRC you might need a small tweak or two but certainly the foundations
were there.

Sometimes regexes are needed, but often Jamie Zawinski is right: Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems. Using the nuclear-powered bulldozer of regular expressions to crack the peanut of a simple fixed-string matching problem is rarely a good idea. -- Steve -- https://mail.python.org/mailman/listinfo/python-list

Please believe Python when it tells you that something is a dictionary. Trust me, the interpreter knows. It doesn't matter how much you want something to be a string, if it is not a string, it isn't a string. -- Steve -- https://mail.python.org/mailman/listinfo/python-list

for what purpose are you trying to run this regex anyway?
it is almost certainly the wrong approach for your task

As the error message says, re.findall() expects a string. A dictionary
is in no sense a string, so passing it in whole like that won't work.
If you know that the name will always show up in the title field, you
can pass just the title:
x = MyRegex.findall(MyDict['/Title'])
Otherwise you will have to loop through all the entries in the dictionary:
for entry in MyDict.values():
x = MyRegex.findall(entry)
# ...and do something with x
I rather suspect you are going to find that the titles aren't in a very
systematic format, though.
