Nedavno tu jimo postoval regexp na mail, hledal jsem neco podobneho pro URL
a
skutecne existuje (viz nize) - otazkou je - zkousel to nekdo? Jak dlouho se
to chroupe a ma smysl neco takoveho pouzit?
dival jsi se dovnitr? kombinuje to vsechny mozne a nemozne protokoly, ale
napr. https:// to nezna.
problem s "chroupanim" bych nevidel - pokud to nezacina jednim z pouzitych
protokolu, tak myslim skonci velmi rychle, pokud zacina, tak se pouzije jen
prislusna cast.. spis bych videl problem s tim, ze se vsema protokolama
najednou si nic neporadi (tzn. je nema smysl vsechny uvadet a kontrolovat) a
treba kontrola email adresy u mailto: je daleko kratsi, nez predchozi podobny
regexp tady na koudinku.. :)
pokud to cele neni uplne hloupost - obecne URI ma gramatiku vzdycky stejnou
(http://www.ietf.org/rfc/rfc2396.txt) - leda by to kontrolovalo i konkretni
moznosti u konkretnich protokolu. ale to u takhle obecne kontroly myslim nema
moc smysl :)
