Hi,
 
I am trying to use SRXTEXT to remove control characters from MTEXT. The colour control characters are something like this: {\\C255; or {\\C2; or just \\C2;
 
I have successfully use the regexp from the command line however I would like to construct a lisp routine but the program seems to function differently. For example.
 
entering the commands:
srxtext
r
\(.\){\\C[0-9];\(.\)
\1\2
L
A
 
will replace "texttext{\\C2;text}text" with "texttexttext}text"
 
this works correctly but if I try to do this:
 
(srxtext "Regular" "\(.\){\\C[0-9];\(.\)" "\1\2" "All")
 
it will return 0. I have managed to get the following to work
 

(srxtext "Regular" "\{\\\\C[0-9];" "###" "All")
 
which will replace {\\C2; with "###" but
 

(srxtext "Regular" "\(.\)\{\\\\C[0-9];\(.\)" "\1\2" "All")
 
will also return 0.
 
why does this not work? Could someone please point me in the right direction? thanks very much!

Please note that LISP has its own processing of the backslash character so you have to double it again.
The right regexp for this case is:
[CODE](srxtext "Regular" "\\(.\\)\\\\C[0-9]+;\\(.\\)" "\\1\\2" "All")[/CODE]

I guess I should have realized that! Thanks very much for the quick response.

I noticed you used the "+" character. Where can I find a list of expressions that SRXTEXT supports?

It is not any special feature of srxText but a standard Posix format of regular expressions.
