| Expression |
^([a-zA-Z0-9]([a-zA-Z0-9\-]{0,61}[a-zA-Z0-9])?\.)+[a-zA-Z]{2,6}$ |
| Description |
Checks domain names. This validates domains based on latest specifications (RFCs 952 and 1123 dealing with hostnames and RFC 1035 dealing with domain name system requirements) except that it only includes realistic fully-qualified domains: 1. requires at least one subdomain 2. allows shortest top-level domains like "ca", and "museum" as longest.
Other validation rules: 1. Labels/parts should be seperated by period. 2. Each label/part has maximum of 63 characters. 3. First and last character of label must be alphanumeric, other characters alphanumeric or hyphen. 4. Does not check maxlength of domain which incidentally is 253 characters of text (255 binary representation).
For a regular expression that matches ALL domains:
^([a-zA-Z0-9]([a-zA-Z0-9\-]{0,61}[a-zA-Z0-9])?\.)*[a-zA-Z0-9]([a-zA-Z0-9\-]{0,61}[a-zA-Z0-9])?$

| Description |
I needed a regular expression to break urls into labled parts. This is what I came up with. Got a few ideas from regexlib.com and from this msdn article. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/script56/html/reconbackreferences.asp
http://www.domain.com/folder does return a match but will not grab the folder name unless there is "/" at the end.
http://www.domain.com/folder/ |

| Description |
Version 1.3.0: I needed a regexp to validate URL's without the ht(f)tp(s):// and include North American domains (like .us and .ca) and there didn't seem to be one available...so I created one. It will also work with ASP QueryStrings and anchor URL's. If you have a problem with the expression or have any suggestions to improve, please write me and let me know. Added .uk domain and expression now allows for URLs that contain JSP session IDs. 4/14/04 - added ability to include URLs that start with server names. |

This is the regular expression I use to add links in my email program. It also ignores those suppose-to-be commas/periods/colons at the end of the URL, like this sentence "check out http://www.yahoo.com/." (the period will be ignored) Note that it requires some modification to match ones that dont start with http. |
