Re: requesting small regex

As you probably know, \d+ matches digits. You want the opposite, which conveniently, perl provides as \D. (Note als: \s&\S; \w&\W; etc. ).

So:

print for split /\D+/, "13%22%3%43";;
13
22
3
43

Note: This applies to ASCII/ISO data; once you get into the world of Unicrap, you're on your own :(

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?

How about something like below? Apart from only digits, it also allows alphabets: `perl -e '$a = "ab%13!3&z* Trial"; $a=~s/(\w+)\W+/$1/g; print $a;'` [download]	[reply] [d/l]

If you need to work with Unicrap, er.. Unicode, use Unicode named property assertions. `print for split /\P{Alnum}+/, 'αβζ#!אש<>!&# +1046;ИУ+sdfg.%12'; αβζ אש ЖИУ sdfg 12` [download] Sigh. Imagine that those were not automatically converted to HTML codepoints.	[reply] [d/l]

magine that those were not automatically converted to HTML codepoints. Posting (small) quantities of Unicrap is the one time (I think) that `<pre></pre>` tags are justified. I'm guessing that \P is 'not the named class'; and that {Alnum} is alpha-numeric. Is theRE no \P{Numeric}?

I'm guessing that \P is 'not the named class'; Good guess and that {Alnum} is alpha-numeric. Is theRE no \P{Numeric}? Yes, but it is spelled \P{Digit}. perldoc perlre has details. Note: I am replying more for the OPs benefit then yours. I am fully aware that you know about perldoc perlre, and are likely a far better perl programmer than I. Cheers BTW the OP DID want to split on non-alphanumerics not just non-numerics. Ok, (s)he did say non-alphanomerics but... ;-)	[reply]
