Regular Expression Extractor problems
I am trying to use the Regular Expression Extractor to process search
results from a web service call. I have a regex that correctly
identifies the data I want, but I do not know why it does not get
assigned to the reference name.
The extractor is set to apply to the main sample only. with the body
(unescaped) option selected. The other settings are:
regex: docid="(\w{32})"
Template: $1$
Match No.: 0
Default Value: NOT FOUND
A small section of the data that is returned and that I am trying to get
a ID pulled from is:
</columns><result
docid="8a8a823435cf9a2c0135d03b08350388"
docTypeId="8a8a823435cf5cd60135cf6ca97a3b7e"
As part of the regex, I have also tried \w* and \w*?
The idea is to get the unique identifier with the surrounding quotes
stripped off. I have Mozilla Firefox's Regular Expression Tester and
the regex does find the right ID along with the quotes and docid=. From
the help, it looks like the parenthesis indicate which part of the
string that matches is to be assigned to the Reference Name variable.
Thank you for your help.

Glad it's sorted.

I've changed the Respnse Field to Body and that set the reference name
variable to:
docid="8a8a823435cf9a2c0135d03b08350388"
The problem is that while it is a hex string, there are many others in
the returned data that resemble it. I need the hex string delimited by
"docid="
As a test I had the template set to "$0$" to show the string I was
matching. That is now at $1$ and the proper delimited string is
returned.
Thank you for your prompt reply. It seems my basic mistake was using
the Body (unescaped) option.

So what does the reference name get set to?

Do you really want a random match?

You could also use
[a-f0-9]+
as the value seems to be lowercase hex.

However, the Firefox plugin may not be using the same RE engine - or
indeed using exactly the same input data.
