regexp for regexp

[robot_rock]

Hi All, is it possible to write regular expression to validate another regular expression?

thanks, max

Regex is for validating strings, regex patterns are strings. So yes, regex can validate a regex pattern.

Thank you! But could you also provide such regexp or link? ;-) I tried to find this info in google, but search doesn't succeed.

thanks, max

I don't know of any links that have that info and it would take some time to make that regex :/ I had a quick look on google too and couldn't spot anything :(

originSH, I appreciate your help! May be somebody else encounter such problem? :)

thanks, max

If you only have to check validity, depending on your platform (i.e. this will work in .NET), just try and use the candidate expression.

Yes, I thought about it, but I would like to have a pattern, that can be inserted in xsd, to verify input xml file, where stored other patterns.

thanks, max
