I have been trying to use RegExp to extract a simpler line of code out of a more complicated one.

Using the RegExp Coach to test my pattern matching this line successfully formats my code using the second, fourteenth, seventeeth and fifth groups match.
which should do something like this:
However, when I copied the pattern into the TextPad replace field I got this:
In other words it treating the second and third elements as back reference \1 plus a literal (as it happens, \1 was spaces).

So, does TextPad have this limit on the number of back references or is there some workaround?

Why do you need more than nine? You are only referencing four in your example. Can you rewrite your expression without all the extra paratheses?

You did not show the Regex you use and you did not show what you want to match.
Thus it is impossible to tell you whether there might be a workaround for the limit of 9 tagged expressions in Textpad.

Because the source string contains lots of parameters, and I only wanted a subset of them.

Yes but it took more than one pass to pick up everything.

Thanks anyway.

But for the other parameters, do you need () for other reasons than back-referencing?
If not, remove them.

I sorry, but I don't understand the correlation between "a lot of parameters" and the need for many paranthetical expressions.

More expressions to match than nine in one run I presume.
For comma/tab delimited files, I found the same problem, i.e. nine matches being insufficient ...
