Regular Expression - How to ignore trailing slash etc

Question

User2130758966 posted

Hey,

I have posted in this forum because it mentioned web.config in its description and thats where my regex is lol. I expect most people here just browse by the unanswered posts page... well thats what i do anyway.

 

I have a problem with my regex, its for urlrewriter.net but the problem is not specific to this.

Here is there regex:

<rewrite url="^/Town/([^\.]+)" to="~/ViewTown.aspx?TownId=${TownLookup($1)}"/>

now this matches:

site.co.uk/Town/Lincoln

but not

site.co.uk/Town/Lincoln/

or

site.co.uk/Town/Lincoln?source=GooglePPC

 

Can anyone tell me how to rewrite the query so that it ignores the extra bits (/ and ?source=GooglePPC).

 

I really got into this regex thing a few weeks ago but now im starting to think Scott Hanselman was right when he said:

"So you've got a problem and you've decided to use Regular Expressions to solve it. Now you've got two problems."

I'm not familiar with URL rewriting, but I assume that you are just trying to capture the town name, and in that case, it surely can only consist of letters?  Or possibly a url-encoded space (%20) or a hyphen? With that in mind, this should work:

/Town/([\w20%-]+)

Great.

Incidentally, Scott Hanselman is wrong. [;)]

 Incidentally if you are going to use Regular Expressions, then download a free copy of Expresso from http://www.ultrapico.com/ExpressoDownload.htm

It is excellent for developing , analysing and testing regular expressions.
