Line[ ]above\n
(Description[ ]"(.*)"\n)?
Line[ ]below\n

[download]
is there any way to differentiate between the following two target strings: 
Line above
Description "xyz"
Line below
 
Line above
Line below

[download]
The problem is the lower string will return blank and the one above also will return blank if "xyz" is not there. Right now I bracket the whole line to know if the line actually exists or not but thats dumb, there must be a better way. Any thoughts? I hope I was clear please ask if you need more clarification on some point.

Thank you.
