problem about Fiddler script and regular expression

[Danny]

Hello Eric ,

Thanks for bring us Fiddler. It's pretty useful.

Here is the problem:

 if (oSession.HostnameIs("www.test.com"))  { 
            oSession.utilDecodeResponse();
             if (oSession.utilFindInResponse("cacheKey",false) > -1){ 
                    var oBody = oSession.GetResponseBodyAsString (); 
                    var regex =/value=\"(.*)\" id=\"cacheKey/i;
                    if(oBody.match(regex)){
                        MessageBox.Show("AAAA" );
                        var cachekey = RegExp.$1;            // <--------------------   Error Line
                      }

Every time i save it, fiddler report :

Object doesn't support this property or method.

I try many times but the problem is still here.

Could you help me?  thanks anyway!

The response body may contain following string:


<input type="text" class="hiddeninput" value="cf7d7002bba04bd2be5de3a3e5fcdb84" id="cacheKey" name="cacheKey" />


Thanks again!

Hello, Danny--

JScript.NET (the language behind FiddlerScript) doesn't allow use of the RegExp object when the /fast option is used (which Fiddler sets): http://msdn.microsoft.com/de-de/library/40a0cc3e%28v=vs.71%29.aspx

Instead of the RegExp.$1 you'll instead need to use one of the other methods of your regex object to perform your extraction.

Hi， 
I encountered with the same problem and not able to solve it.
The string in the oBody is:  "count"=7
 I try to grep it by: var patt = /"count"=(\d+)/
and finally doubles the number.
How to do it without using $1?

Thanks.

Hello, Breeze--

I think you're asking: "How do I manipulate a string in .NET?" You can either use .NET Regular Expression objects or simple string parsing.

Your best bet would be to ask such questions in a general programming forum, like StackOverflow.com, for instance, as they don't really have anything to do with Fiddler.
