Jmeter RegEx Extractor - regex

I am new to Jmeter's Regular Expression Extractor. For an HTTP Request, I am getting an HTML Response. I want to extract all the URL strings.
This is one example; the number after tools in the id part changes.
li><a id="link_sub_sub_cat_tools14874187"
href="/EN/shop/tools/tools.cat"
class="cat-/tools/tools"><span>
li><a id="link_sub_sub_cat_tools14874787"
href="/EN/shop/tools/tools.cat"
class="cat-/tools/tools"><span>
li><a id="link_sub_sub_cat_tools14874287"
href="/EN/shop/tools/tools.cat"
class="cat-/tools/tools"><span>
How can this be done?

I have created jMeter tutorials for the very subject.

To extract url strings use regular expression- href="(.+?)"
To extract number after after tools in the id part use regular expression- id="link_sub_sub_cat_(.+?)"

Regex Problem in Extractor Regular Expression - JMeter

I'm using the regular expression extractor in JMeter to extract data from a parameter.
However, the data is not being extracted.
Response:
{
"access_token": "8d06ba17-2e51-31d2-aa55-25e4a3ecd33b",
"expires_in": 7200
}
Extractor:
Name reference: token
Regular expression: "access_token": "(.+?)"
Match: $1$
Request parameter use
v1/api/users?client=${token}
Use instead JSON Extractor with JSON Path Expressions as $.access_token
JSON PostProcessor enables you extract data from JSON responses using JSON-PATH syntax. This post processor is very similar to Regular expression extractor. It must be placed as a child of HTTP Sampler or any other sampler that has responses. It will allow you to extract in a very easy way text content
Your access_token is a GUID-like structure so you can use the following regular expression instead:
([A-Fa-f0-9]{8}[\-][A-Fa-f0-9]{4}[\-][A-Fa-f0-9]{4}[\-][A-Fa-f0-9]{4}[\-]([A-Fa-f0-9]){12})
Alternatively you can try to secure yourself by adding optional whitespace meta character like:
"access_token"\s?:\s?"(.+?)"
More information:

Perl 5 Regex Cheat sheet
And finally your response is in JSON format so it makes more sense to use JSON Extractor, the relevant JsonPath query would be as simple as:
$.access_token

How to create regex

can somebody help me how to create regex from this? I need only text after a_n: " so I need only this text. e.g. jgoijODIJGojsklfj4dgdg_797gsdg-df_gsdfh-dhfGSDhfdsg-dfg
{
"a_n": "jgoijODIJGojsklfj4dgdg_797gsdg-df_gsdfh-dhfGSDhfdsg-dfg",
"type": "something",
"uuser": "userid",
"expire": "6018"
}
If you can, just use a JSON parser to get the value. Otherwise you can use
/{.*\"a_n\": \"(.*)\".*/
You can achieve this with JSONStream.
cat file.json | JSONStream '.a_n'
And also with jq:
jq .a_n file.json
Please have a look (how to use a regular expression to extract json fields?)
regex should be,
/"a_n":\ ?"((\\"|[^"])*)"/i
To extract this in JMeter:
Add a jp#gc - JSON Path Extractor under your request sampler.
To extract the required data, you have to set like this:
Your extracted value will be saved in the variable Jsonvar.
Now You can use this variable other subsequent requests.
JMeter's Regular Expression Extractor uses Perl-5 style regular expressions so the relevant configuration would be:
Regular Expression: "a_n": "(.+?)"
Template: $1$
Also be aware that it makes more sense to use JSON Extractor to work with JSON responses. The relevant JSON Path query would be as simple as $.a_n

jmeter regular expression extract part of returned url

I need to extract a part of returned url from a GET Request. As the following :
https://happy.new.year/idp/1Z8a8/resumeSAML20/idp/startSSO.ping
I need to extract this value: 1Z8a8 and I need to put it into a new POST request.
Which regular expression do I have to use in regular expression extractor configuration?
You could use this:
(.+?)\/
This will match the parts between slashes. The one you want is the fourth match.

Regular expression for URL for Google Analytics

I'm trying to set up a goal on Google Analytics and want to match a regular expression against the following url:
/tasks/[random characters of random length]/complete
An example input url would be:
/tasks/12444ab22aaa7/complete
Any ideas?
^/tasks/.*/complete$
Validate with a search in the Top Content report before using in a filter.
Perhaps this
\/tasks\/[^/]*\/complete
