Hi,

Expresso from Ultrapico (available at https://www.ultrapico.com/Expresso.htm) is a very good - and free :) - tool for learning and creating regular expressions. Main features are:
- Expression library with most-wanted regular expressions (!!!)
- Expresso Analyzer interprets and diagrams a regular expression to aid in understanding and debugging
- Build complex regular expressions by selecting components from a palette
- Test expressions against real or sample input data
- Display all matches in a tree structure, showing captured groups, and all captures within a group
- Build replacement strings and test the match and replace functionality
- Highlight matched text in the input data
- Test automatically for syntax errors
- Maintain and expand a library of frequently used regular expressions
Cheers,
Olivier

Hi Tiago,

In the Text solution trial I've tried several search patterns: ^1{1}* and ^1{1}+ all give me an error message. Am I using bad syntax?

Also, do you know any good regular expressions reference (MSDN, probably...)?

Cheers,
Pedro Gonçalves

Hi Pedro,

I think you are lacking some parenthesis in your regular expression. Maybe you want:
([^1]{1})* - Means that you accept zero or more words with one character only that is not '1'.
([^1]{1})+ - Means that you accept one or more words with one character only that is not '1'.

Is this what you wanted?

You can find the MSDN regular expression reference here: https://msdn2.microsoft.com/en-us/library/az24scfc(VS.71).aspx (to use use this link copy it to your browser's address bar)

NVM me,
