Regexp not working

[chatiman]

Hello,

I'm tryng to mach all url of a domain :
http://host1.domain.com/
http://host2.domain.com/
http://www.domain.com/

For that I'm using the following regexp:
/http:\/\/[^\.]+domain.com/

I can't understand why it is not working.

Anyone knows ?

/http:\/\/[^\.]+domain.com/

You are missing a dot after the first component of the name.

m#http://[^.]+.domain.com#

I don't know if you realise that . doesn't need escaping in a character
class; or if you care that this will match lots of invalid UR[LI]s (such
as http://%#>?&.domain.com/). You may wish to use Regexp::Common, which
will correctly match various bits of valid URIs.

Not in character classes, but outside of them it does.

m#http://[^.]+\.domain\.com#

Hello,

I can't understand why it is not working.

Anyone knows ?

m#http://[a-zA-Z0-9][a-zA-Z0-9-]*?.domain.com#

Will match only match valid bits (letters, numbers and -s, without a - as
the first character. That probably won't cover everything, you may want to
look at the RFCs.

Nuts, forgot to escape the .s, try
m#http://[a-z0-9][a-z0-9-]*\.domain\.com#oi instead.

Hello,

For that I'm using the following regexp:
/http:\/\/[^\.]+domain.com/

Does the following work for you?

m#http://[^.]+\.domain\.com#

For me it does, so it might be a good start.
Btw:
I would rather use s.th. like
m#http://[^\.]*\.?domain.com# which matches also
http://domain.com

m#http://[a-zA-Z0-9][a-zA-Z0-9-]*?.domain.com#

Will match only match valid bits (letters, numbers and -s, without a - as
the first character.

So will this:

m#http://\b[a-zA-Z0-9-]+\.domain\.com#

But that would match 'http://www-.domain.com', better make sure
the last one isn't a hyphen either:

m#http://\b[a-zA-Z0-9-]+\b\.domain\.com#

 

[Tad McClellan]

m#http://[a-z0-9][a-z0-9-]*\.domain\.com#oi instead.

What do you think the m//o option will do for you there?
