Question

I’m not very well versed with regular expressions so i need some help. I’m using a jQuery dynacloud plugin that breaks at an identified point in my code when a regex match happens. i need someone to help me figure out what this regex matches

/^[a-z\xE4\xF6\xFC]*[A-Z\xC4\xD6\xDC]([A-Z\xC4\xD6\xDC\xDF]+|[a-z\xE4\xF6\xFC\xDF]{3,}

Any help please!!

Answer 1

the \x** parts translate to a special charachter, if you replace those you basically get:

/^[a-zäöü]*[A-ZÄÖÜ]([A-ZÄÖÜß]+|[a-zäöüß]{3,})/

I’ll take it apart for you:

^ beginning of string

[a-zäöü] characterset: any character from a to z or äöü * zero or more times

[A-ZÄÖÜ] characterset: any character from A to Z or ÄÖÜ just once

( start of group

[A-ZÄÖÜß] another character set, you should get it now 🙂 + one or more times

| or

[a-zäöüß] characterset, {3,} 3 or more times

) end of group

also, you missed a )/ at the end, the / at the start and end means whats in between is the regex.
