Regular expression help needed

Rails
1

Hello

I am very week with regular expressions. It may be too easy for someone.

I have following regular expression

loc_content_re = /(?:([A-Za-z\s:]?):)?([\s\S])/

content = “HYDERABAD/NEW DELHI: Andhra Pradesh chief minister was …”

I wanted to extract “HYDERABAD/NEW DELHI” from above content

match_re = loc_content_re.match(content)

location = $1
plain_content = $2

It shows location nil and plain_content as passed

One more,

What will be the regular expression to extract
IANS and
3 September 2009, 02:57pm IST
from following
" IANS 3 September 2009, 02:57pm IST "

Thanks !
Sandip

Well for the example string you have given, this does the job :
reg = /(.):\s+(.)/
s = “HYDERABAD/NEW DELHI: Andhra Pradesh chief minister was …”
reg.match(s)
location = $1 # = “HYDERABAD/NEW DELHI”
plain_content = $2 # = “Andhra Pradesh chief minister was …”

Thanks & Regards,

reg = /(.)\s([0-9]\s.)/
s = " IANS 3 September 2009, 02:57pm IST "
reg.match(s)
location = $1.strip # = “IANS”
plain_content = $2.strip # = “3 September 2009, 02:57pm IST”

If you need RegExp help this would help you :
s = ‘Bangalore.txt’
regexp = /(.).(/)/
regexp.match(s)
baseName = $1 # = “Bangalore”

But I must say, you should try google a bit more often as Abhinav
mentioned.
