RegEx not finding matches ... but it should
-
*************************** For the record this is a cross-post. I dont want to get anyone mad it's just that i really need help with this Original Post[^] *************************** Hey All, I am experiencing a strange issue, i have built and tested my RegEx in Expresso but when I call it from my code (C#) I am not getting any matches. If i step through and grab the values from the variables and put those in Expresso it works .... RegEx:
Lead\sID\sNumber:\s*(?<LeadNumber>[^\r\n]*)(?:\r\n)+ Prospect\sName:.*(?:\r\n)+ Prospect\sContact:.*(?:\r\n)+ Prospect\sPhone:.*(?:\r\n)+ Marketing\sCampaign:.*(?:\r\n)+ Prospect\sInformation:\s*(?:\r\n)+ ===============\s(?:\r\n)+ (?<Company>[^\r\n]*)(?:\r\n)+ (?<Address1>[^,]*),\s(?<Address2>[^\r\n]*)(?:\r\n)+ (?<City>[^,]*),\s(?<State>[^\r\n]*)(?:\r\n)+ (?<Country>[^,]*),\s(?<Zip>[^\r\n]*)(?:\r\n)+ Contact\sName:\s*(?<FirstName>[^\s]*)\s(?<LastName>[^\r\n]*)(?:\r\n)+ Contact\sPhone:\s*(?<Phone>[^\r\n]*)(?:\r\n)+C#:MatchCollection myMatches = Regex.Matches([Text], [RegEx], RegexOptions.Multiline | RegexOptions.IgnoreCase | RegexOptions.Compiled | RegexOptions.IgnorePatternWhitespace | RegexOptions.CultureInvariant);[Text] = the body of an email [RegEx] = the above pattern Any input or ideas would be greatly appreciated. -

Then you know the problem is in the part you last removed. OTOH I would never come up with such a complex Regex pattern in the first place. It is just unreadable. And what happens if someone somewhere decides to add/delete a space, a new line, whatever to the e-mail format? IMO you need several smaller operations to extract the fields individually, your code looks like a maintenance nightmare to me. :)

Hello Luc, Normally i would agree with you 200%, however this is a subcontract project which is going to be used by other developers. They wanted me to allow for configuration of the email parsing by having a setting which contains the RegEx to use. You can find the solution to my problem here[^], i didn't want to keep cross posting. Thanks again for your input.
If at first you don't succeed ... post it on The Code Project and Pray.
