Regular expression for validating url in c - arab planetalove dating

@adamrofer, it seems the URL " you are testing against is actually a valid URL. Just test it, it exists and resolves correctly to a Georgia State page.

I am curious to try the effects of this change on my current tests. @eluck, it is written in the comments: 'TLDs have been made mandatory so single names like "localhost" fails'.

// Regular expression for URLs // Based on // Improved to only pickup links begining with http https ftp ftps mailto and www $regex = "_(? The above is also true for decimal notations, various forms of IPV6 URLs and other "non-human" URLs.

I tested them once more within my environment (Javascript) and everything works as expected. Nobody will type/remember "Puny Code" URLs and the regex already supports international UTF-8 URLs.

$_iu S I have added simple network ranges validation, the rules I used are: - valid range 1.0.0.0 - 223.255.255.255, network adresses above and including 224.0.0.0 are reserved addresses - first and last IP address of each class is excluded since they are used as network broadcast addresses since I don't think this is worth implementing completely in a regular expression, a following pass should exclude the Intranet address space: 10.0.0.0 - 10.255.255.255 172.16.0.0 - 1.255 192.168.0.0 - 192.168.255.255 the loopback and the automatic configuration address space: 127.0.0.0 - 127.255.255.255 169.254.0.0 - 169.254.255.255 while the local, multicast and and the reserved address spaces: 0.0.0.0 - 0.255.255.255 (SPECIAL-IPV4-LOCAL-ID-IANA-RESERVED) 224.0.0.0 - 239.255.255 (MCAST-NET) 240.0.0.0 - 255.255.255.255 (SPECIAL-IPV4-FUTURE-USE-IANA-RESERVED) should already be excluded by the above regular expression.

Negative lookahead is used instead NOTE, that package does fuzzy search, not strict validation. If they copy it out and back into a browser so they may not know what's wrong with it upon visual inspection.

He also sliced up the Unicode ranges :=), that's the reason his one is so long :) = 224.0.0.0/8 are excluded by the second validation block.

This a very minimal list of tests to add to your testings: PASS " " " FAIL " " " " " Need testing :) Need to mention I took the idea of validating the possible IP address ranges in the URL while looking at other developers regular expressions I have seen in your tests, especially the one from @scottgonzales.

Code can be found at: https://github.com/garycourt/uri-js I changed it a little bit so that it's valid in Ruby.

It uses a much larger regular expression then this one.

In the list of URLs failing validation that you sent above only the first one is a valid URL (" all the others are not validating against the regex. I am most likely inclined to also remove IPV4 validation from the base regex, nobody remember these numbers and they will most likely change in time.

However I disagree about having patterns that will never be typed by users like "IPV6" and "Puny Code".
