Hi, I'm newbie to ruby, but I try searching a lot for my problem... I need to extract from an enormous text file, in natural language, for two separated element in the same line and put them in a new file. Example: IIS - IPSIASAR L. DA VINCI (XN\_\_\_\_01) - Responsabile: ENRICO FLAIANO VIA MONTE S. ROCCO, 15 PINETA SIGNORINI - 67100 L'AQUILA (AQ) - tel. 0862 22112 - fax. 0862 22300 email : [ipias\_aq@yahoo.it](mailto:ipias_aq@yahoo.it) - url:[http://www.istitutoleonardodavinciaq.191.it](http://www.istitutoleonardodavinciaq.191.it) I need to extract the code (XN\_\_\_\_01) and the relative email "ipias\_aq@yahoo.it", put them in a CSV file or a sort of. May I do this in ruby? Thank's very much for any help and so sorry for my bad english... > **···** > > -- > Posted via [http://www.ruby-forum.com/](http://www.ruby-forum.com/). ---

You can do it using a capture group: [http://ruby-doc.org/docs/ruby-doc-bundle/Manual/man-1.4/syntax.html#regexp](http://ruby-doc.org/docs/ruby-doc-bundle/Manual/man-1.4/syntax.html#regexp) and examples here: [Regex Tutorial - Parentheses for Grouping and Capturing](http://www.regular-expressions.info/brackets.html) > **···** > > On Tue, May 18, 2010 at 7:39 AM, Andrea Carmisciano \ wrote: > > > Hi, I'm newbie to ruby, but I try searching a lot for my problem... > > > > I need to extract from an enormous text file, in natural language, for > > two separated element in the same line and put them in a new file. > > > > Example: > > IIS - IPSIASAR L.

It's a bit difficult to guess which parts of your line are stable and which not, i.e. how to build the regexp. Can you post, say 5, different lines so we can recognize the pattern?
