Re: A quick Regex query

I am using the following: [0-9]{4} [A-Za-zÅØ]{2,20} to extract data like: 1000 Øslo How can I alter the above to limit to ONLY 4 digits, or in other words exclude: 11000 Beograd Please note that what I am extracting from is NOT at the begining of a line, so I can't use the ^ first.

Well, it depends what "usually is" (can be) before what you want to get and the regex family your using. If it's PCRE, you may try something like "\b\d{4} [A-Za-zÅØ]{2,20}" \b = "word boundary", it's basically a word separator and it's not included in the result you get (since it's more a "position" rather than a "string")

Also, you may notice a couple of 'special' characters in my expression 'Å + Ø' By putting them in they seem to work fine, but is this the best way of doing it?

I think it is. IIRC what you define in a "class" (i.e. between square-brackets) is quite fast; e.g. "[ab]" fastest than "(a|b)", is that what you were asking? -- Atentamente, J.
