character-properties

How can I trim a string(6) " page" , where the first whitespace is a 0xc2a0 non-breaking space? I've tried trim() and preg_match('/^\s*(.*)\s*$/u', $key, $m); . Another question: How can I reliably copy these characters? They seem to be converted to "normal" spaces, which makes it hard to debug. preg_replace('/^[\pZ\pC]+|[\pZ\pC]+$/u','',$str); Anti Veeranna PCRE unicode properties properties can be used to achieve this Here is the code that I played with and seems to do what you want: <?php function unicode_trim ($str) { return preg_replace('/^[\pZ\pC]+([\PZ\PC]*)[\pZ\pC]+$/u', '$1', $str); }

Okay, I have read about regex all day now, and still don't understand it properly. What i'm trying to do is validate a name, but the functions i can find for this on the internet only use [a-zA-Z] , leaving characters out that i need to accept to. I basically need a regex that checks that the name is at least two words, and that it does not contain numbers or special characters like !"#¤%&/()=... , however the words can contain characters like æ, é, Â and so on... An example of an accepted name would be: "John Elkjærd" or "André Svenson" An non-accepted name would be: " Hans ", "H 4 nn 3

I have read thru the other questions at Stackoverflow, but still no closer. Sorry, if this is allready answered, but I didn`t get anything proposed there to work. >>> import re >>> m = re.match(r'^/by_tag/(?P<tag>\w+)/(?P<filename>(\w|[.,!#%{}()@])+)$', '/by_tag/xmas/xmas1.jpg') >>> print m.groupdict() {'tag': 'xmas', 'filename': 'xmas1.jpg'} All is well, then I try something with Norwegian characters in it ( or something more unicode-like ): >>> m = re.match(r'^/by_tag/(?P<tag>\w+)/(?P<filename>(\w|[.,!#%{}()@])+)$', '/by_tag/påske/øyfjell.jpg') >>> print m.groupdict() Traceback (most recent

In .net you can use \p{L} to match any letter, how can I do the same in Python? Namely, I want to match any uppercase, lowercase, and accented letters. Python's re module doesn't support Unicode properties yet. But you can compile your regex using the re.UNICODE flag, and then the character class shorthand \w will match Unicode letters, too. Since \w will also match digits, you need to then subtract those from your character class, along with the underscore: [^\W\d_] will match any Unicode letter. >>> import re >>> r = re.compile(r'[^\W\d_]', re.U) >>> r.match('x') <_sre.SRE_Match object at
