1. Is there any chance of getting your source data changed? The whole purpose of a field delimiter is it's not part of your data. So get the comma field delimiter changed to ~, ^, |, etc.
2. Since your data appears to be name=value pairs separated by a delimiter, use the FIELD function to parse your data after fixing #1 above. Then, use the FIELD function on THAT to parse name/value (on the = sign).
3. When name equals your field of interest, you've found your field.
4. If you don't mind doing this outside DS, let me know. Somewhere I *may* (I'll have to dig it up) find a regular expression that ignores delimiters between quotes. I certainly didn't think it up - I found it in comp.lang.perl. It's really ugly with a bunch of backreferences (all this is from memory).
Your life is a lot easier if you address #1 above...
