I need some regex help...

regex_help.txt

Solved, with some help from StackOverflow that I apparently missed the first time around 
(http://stackoverflow.com/questions/2013124/regex-matching-up-to-the-first-occurrence-of-a-character):

/<simpleChoice[^>]*>/

Match "<simpleChoice" plus any and all characters that do not match ">" followed by a ">".

[^>]* is a set of "zero or more characters that do not match >"


****************


I have this xml content (below), and I need to insert a "<content>" tag right after the <simpleChoice> tag using ruby gsub. I'm running into 
trouble with the regex match due to the attributes in the <simpleChoice> tag. What I've tried is this:

gsub(/<simpleChoice.*>/, '\\0<content>')

But, the .* matches everything to the end of the xml, not just the end of that tag, so I end up with the original xml with a <content> tag 
at the very end.

How do I prepare the regex to match the "<simpleChoice " text plus only the characters up to the first ">" that is encountered?
