Dynamic Parameters with RegEx

[Surendra Viswanadham <sv...@gmail.com>]

Hi,

I am writing a simple test script for testing a web application. I am trying
to extract a parameter from the response of a request and use it as part of
subsequent requests.

Example
------------

if the response had the following data:
.....<a href="something.com?param1="val1"&param2="123456">...</a>.....

I want to extract 123456 which i know is going to be a 6 digit number.  I
tried the following after adding a regular expresion extractor as the post
processor for the request obtaining this response.

Ref Name: ref1
Regular Expression: param2=([\d{6}])
Template: $1$
Match No: 0
Default Value:

That script is never successful and goes to the default value.

1) Is the script right or is there something else wrong?
2) Do i need to declare ref1 in the user variables component or is it
implicit once i give it as a ref name ( I tried both ways)

Any ideas would help. Thanks.

Surendra

Aren't you missing the quotes around the regex?

So param2="([\d{6}])"

Hey Sebb,
Thanks a lot. That worked pretty much. Additionally I needed some other
regex help but after looking around I found a pretty cool application,
http://weitz.de/regex-coach/ which helps the helpless :)

Hi Sebb
Thanks for the response. Sorry for the mistaken info. There are no quotes
for either of the values. So the response would be

 .....<a href="something.com?param1=val1&param2=123456">...</a>.....
In which case the regex param2=([\d{6}]) should work right ?

The [ and ] are used to enclose character classes, i.e. [abc] means a
or b or c - but only one such character.

What you need is

param2="(\d{6})"

You need the final " otherwise it would match: param2="1234567

0 means pick a random match - did you mean that?
