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

• Introducing regular expressions
• Mastering regular expressions

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.

Excellent find Takashi, thanks.
