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, Dhruva S… Joan Crawford[http://www.brainyquote.com/quotes/authors/j/joan\_crawford.html](http://www.brainyquote.com/quotes/authors/j/joan_crawford.html) - “I, Joan Crawford, I believe in the dollar.

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” Thanks & Regards, Dhruva S… ## Ogden Nash [http://www.brainyquote.com/quotes/authors/o/ogden\_nash.html](http://www.brainyquote.com/quotes/authors/o/ogden_nash.html) “The trouble with a kitten is that when it grows up, it’s always a cat.” ---

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.
