Hi All,
I have, many times came across the transformers that use RegExp but I am not sure about how to use it intelligently. I have also read some Q&As; from @takashi and @gio and from tcl site and I was wondering if I could use it more efficiently. I would like to understand more about the codes and expressions. Can someone help me with that?
Some good websites to use to get you started are as follows...

Hi
Regular expressions have been around for a long time and are used not only in FME, but in many programming languages and applications.
If you look around on the web you'll find a lot of free tutorials and references. I particularly like this reference.
There are also many books on the subject, in particular I'd recommend

The Help of the FME transformer StringReplacer contains some examples and a link to the Rubular test site.
Check out this very complete explanatory work from
Regular Expressions
The Complete Tutorial

It used to be a free download, nowadays a little contribution is required.

Rubular is handy, but is flavor limited. Notepad++ you can also test and built them as are Regbuddy etc.etc.
FME has mixed hadnling of regexp (wich i hope will be solved.)
Fme cant even find and replace a comma using a regexp..lol. (use the unicode string to this) Stringserachers & co. are very limited, no switches, forward lookups etc..
Best to use tcl regepx in attribute creators, testers etc. Basicaly everywhere you can use an expression u can use tcl regexp commands.
Related information. In FME 2016.0, the Regular Expression Editor has been introduced. You can use this editor to enter a regex to a regex parameter field of some transformers (e.g. StringSearcher) and test your regex with any test string.
