What I'm really after is a URL I can go to that gives me a list of tld's in a form I can use in code...
Ie: http://www.listoftlds.com/csv Gives me: com,uk,net,org etc... Don't worry. The reason I wanted it is for a regex to check if a domain is valid (or at the very least follows the rfc's). Here it is: ([a-z0-9]([-]|[a-z0-9])*[a-z0-9][.])+(.ac|.ad|.ae|.af|.ag|.ai|.al|.am|.an|.a o|.aq|.ar|.ar|.as|.at|.au|.aw|.az|.ba|.bb|.bd|.be|.bf|.bg|.bh|.bi|.biz|.bj|. bm|.bn|.bo|.br|.bs|.bt|.bv|.bw|.by|.bz|.ca|.cc|.cd|.cf|.cg|.ch|.ci|.ck|.cl|. cm|.cn|.co|.coop|.com|.cr|.cu|.cv|.cy|.cx|.cz|.de|.dj|.dm|.do|.dk|.dz|.ec|.e du|.ee|.eg|.eh|.er|.es|.et|.eu|.fi|.fk|.fm|.fo|.fr|.fx|.ga|.gd|.ge|.gf|.gg|. gh|.gi|.gl|.gm|.gn|.gov|.gp|.gq|.gr|.gs|.gt|.gu|.gy|.gw|.hm|.hn|.hk|.hr|.ht| .hu|.id|.ie|.il|.im|.in|.info|.int|.io|.iq|.ir|.is|.it|.je|.jm|.jo|.jp|.ke|. kg|.ki|.kid|.km|.kn|.kp|.kr|.ky|.kw|.kz|.la|.lb|.lc|.li|.lk|.lr|.ls|.lt|.lu| .lv|.ly|.ma|.mc|.md|.mh|.mg|.mil|.mk|.ml|.mm|.mn|.mo|.mp|.mq|.mr|.ms|.mt|.mu |.museum|.mv|.mw|.mx|.my|.mz|.na|.name|.nc|.ne|.net|.nf|.ng|.ni|.nl|.no|.np| .nr|.nu|.nz|.om|.org|.pa|.pe|.pf|.pg|.ph|.pk|.pl|.pm|.pn|.pr|.pro|.pt|.pw|.p y|.qa|.re|.ro|.ru|.rw|.sa|.sb|.sc|.sd|.se|.sg|.sh|.si|.sj|.sk|.sl|.sm|.sn|.s o|.sr|.st|.su|.sv|.sy|.sz|.tc|.td|.tf|.tg|.th|.tj|.tk|.tm|.tn|.to|.tp|.tr|.t t|.tv|.tw|.ua|.ug|.us|.uk|.um|.uy|.uz|.va|.vc|.ve|.vg|.vi|.vn|.vu|.wf|.ws|.y e|.yt|.yu|.za|.zm|.zw|.ad|.ae|.al|.am|.at|.az|.ba|.be|.bf|.bg|.bh|.bj|.by|.c f|.ch|.ci|.cm|.cv|.cy|.cz|.de|.dj|.dk|.dz|.ee|.eg|.er|.es|.eu|.fi|.fo|.fr|.g a|.gb|.ge|.gg|.gh|.gi|.gn|.gq|.gr|.gw|.hr|.hu|.ie|.il|.im|.io|.iq|.ir|.is|.i t|.je|.jo|.ke|.kg|.kz|.lb|.li|.lr|.lu|.lv|.ma|.mc|.md|.mk|.ml|.mt|.ne|.ng|.n l|.no|.om|.pl|.pt|.qa|.ro|.ru|.sa|.se|.si|.sj|.sk|.sl|.sm|.sn|.su|.sy|.td|.t j|.tm|.tn|.tr|.ua|.ug|.uk|.uz|.va|.ye|.yu) Exciting isn't it? Basically if you put [a-zA-Z0-9_and whatever else works in an email address]@ and then the above, you can test if an email Address has a valid domain. NOTE: The regexes are case sensitive and I didn't put the a-zA-Z in because you can just do a case insensitive match with the above regex Seems pointless to me! To make it simpler, just use this (although the tld won't be checked): ([a-z0-9]([-]|[a-z0-9])*[a-z0-9][.])+([a-z0-9]([-]|[a-z0-9])*[a-z0-9]) To put in the most common tlds (you can put more in), you could easily do this: ([a-z0-9]([-]|[a-z0-9])*[a-z0-9][.])+(([a-z0-9]([-]|[a-z0-9])*[a-z0-9])|com| co[.]uk|net|org|com[.]uk) Which is actually syntactically valid according to the RFC! It basically says: Domains MUST start and end in a letter or digit Between the start and end letter/digit, the domain can contain 0 or more letters, digits or hyphens Domains are delimited by dots (or periods if you're american) There can be any number of subdomains up to 63 (min) or 255 (recommended) believe it or not! Did you know that a--b.com is a valid domain name? Didn't realise you could have double hyphens in a domain name (although why would you?) These regexes are untested, but you should be able to figure it out! HTH Paul PS The main regex is this: [a-z0-9]([-]|[a-z0-9]) And [.] as a delimiter and not much more Everything stems from this one regex ------------------------------------------- Paul Johnston PJ Net Solutions Ltd http://www.pjnetsolutions.com [EMAIL PROTECTED] +44 (0)7866 573013 -- ** Archive: http://www.mail-archive.com/dev%40lists.cfdeveloper.co.uk/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] For human help, e-mail: [EMAIL PROTECTED]
