RegEx Support in Ensemble

[Viraj]

Hi,
I need to know if ensemble supports regex just like java or .net. I
need to do some string manipulations using regex in ensemble.

Hi Viraj,

I've been using pattern matching in Ensemble to achieve some of what
regular expressions do in other languages, though not as powerful as a
full regular expression implementation.
You can read more about it here:
http://docs.intersystems.com/ens20102/csp/docbook/DocBook.UI.Page.cls?KEY=G
COS_operators#GCOS_operators_pattern

Hope this helps!

Ricardo

Hi Viraj

I have been working on a regular expression object which is near enough ready for you to have if it works for you. The following code snippet gives a feel for how it is used.

USER>set re=##class(Library.RegExp).%New()
USER>do re.Compile("[^!@\s]+@(([a-zA-Z0-9\-]+)\.)+([a-zA-Z0-9]+)","gi")
USER>set re.input="address1: mai...@domain.com address2: i...@yahoo.co.uk"
USER>write re.Execute()
1
USER>write re.lastMatch
mai...@domain.com
USER>w re.savedStrings.GetAt(2)
domain.
USER>write re.Execute()
1
USER>write re.lastMatch
i...@yahoo.co.uk

If you would like it then let me know which version of Ensemble you are running.

Best regards

Hi All,
Thanks for your replies.
Robert, I tried your code to initiate a new RegExp object but looks
like ensebmle does not support it. I also checked the documentation of
ensemble.
I am using ensemble v2010.2

Thanks

Hi Viraj

Library.RegExp is a custom object written by myself and is not
supported by InterSystems. I am happy to send you the code for you to
import and use on your Ensemble instance if you wish.

Best regards
