RegEx match open tags except XHTML self-contained tags

I have a text file consist of conversion instruction templates. I need to parse this text file,

I need to match something like this:

(Source: <element>)

And get the "element".

Or this pattern: 

(Source: <element attr="name" value=""/>)

And get "element attr="name"".

I am currently using this regex: 

\(Source:\ ?\<(.*?)\>\)

Sorry for being a newbie. :)

Thanks for all your help.

Try this Regex for detect attibs by both ” or " characters:

\(Source:\s+<(\w+\s+(?:\w+=[\"”][^\"”]+[\"”])?)[^>]*>\)

and your code:

var result = Regex.Match(strInput, 
                         "\\(Source:\\s+<(\\w+\\s+(?:\\w+=[\"”][^\"”]+[\"”])?)[^>]*>")
                  .Groups[1].Value;

explain:

(subexpression) Captures the matched subexpression and assigns it a zero-based ordinal number.

? Matches the previous element zero or one time.

\w Matches any word character.

+ Matches the previous element one or more times.

  • for example you have a string = (Source: ).... I want to get this--> Property FormalName="Country", your regex only extract "Property" – jomsk1e Nov 08 '12 at 07:02
