Goal: 

Match the first word (named group <type>) after any number of white spaces then match the last occurence of space+colon+equal+space+opening square ie ( := [) and return the opening square along with all characters upto and including a last closing square + semi-colon + carriage return (named group <value>). The named group <type> must ignore all characters between after the first matched word and the start of named group <value>.

Problem:

The regular expression below matches if there are no characters are between <type> and <value> other than space+colon+equal+space ie ( := ), however if characters do exist then it does not match...ugh!

Current Match:

<type> : InputForceData

<value> : [0,2,0,6,1,0,0,0,3]

Desired Match:

<type> : InputData

<value> : [0,1,2,3,4]

<type> : InputForceData

<value> : [0,2,0,6,1,0,0,0,3]

Platform:

.Net (VS2008)

Regular Expression

\s*(?<type>\b\w+\b*?)\s:=\s(?<value>\[.*?);\r

Sample Text:

   CONNECTION StandardInput (Rate := 10000,
                             EventID := 0)
     InputData (COMMENT.DATA.0 := "P903_RUN_STAT",
COMMENT.DATA.1 := "P905_RUN_STAT") := [0,1,2,3,4];
     InputForceData := [0,2,0,6,1,0,0,0,3];
   END_CONNECTION

This worked for me:

          Regex re = new Regex(@"(?<type>\b\w+\b.*?)\s*(?:\([^)]*\))?\s*:=.*?(?<value>\[[^\]]*\]);");
          MatchCollection mc = re.Matches(sourcestring);

Worked great for the sample text however when I test real world text it truncates at the first closing square whenvever <value> contains nested squares.

Sample Text:

 CONNECTION StandardInput (Rate := 10000,
                             EventID := 0)
     InputData (COMMENT.DATA.0 := "P903_RUN_STAT",
COMMENT.DATA.1 := "P905_RUN_STAT") := [0,[1],2,3,4];
     InputForceData := [0,2,0,6,1,0,0,0,3];
   END_CONNECTION

Current Match:

<type> : InputData

<value> : [0,[1]

<type> : InputForceData

<value> : [0,2,0,6,1,0,0,0,3]

Desired Match:

<type> : InputData

<value> : [0,[1],2,3,4]

<type> : InputForceData

<value> : [0,2,0,6,1,0,0,0,3]
