Jmeter Regular expression extractor and parsing into request - jmeter

In Jmeter, I can able to extract the value using regular expression extractor, but while parsing the value I need some changes in the value as below.
Example,
Suppose If I extract this value in regular expression extractor (single Value in multiple lines),
PHNhbW+xwO
U0FNTDoyL
cmFjbGUu+
Here
I Need to replace + by %2B, need to add %OD%OA at the end of each line and multiple lines to a single line as below.
PHNhbW%2BxwO%OD%OAU0FNTDoyL%OD%OAcmFjbGUu%2B%OD%OA
I need to parse this as a single parameter value.

I think you can use __javaScript() function which allows calling arbitrary JavaScript code and inside JMeter __javaScript() funciton you can call EcmaScript EncodeURIComponent() function
It will automatically convert all newline characters \r\n to %OD%OA and + to %2B and in fact any character except alphanumeric and these ones:
_ . ! ~ * ' ( )

How do I use multiple values of all matches returned by regular expression in jmeter in a single HTTP request

I'm capturing multiple values with a regular expression, and that expression returns 20 matches as shown in image RegExMatches,
My regular expression is something like this RegEx.
How do I use multiple values in post data of my HTTP request which is something like PostData
I tried with MatchNR and -1 and call with ${candidateGUID_gN} N being the match number but this didn't workout.
How do I use the Extracted values in Post data ? or will I have to make different Regular Expressions for each value ?
I think the only way of achieving this is building your request using JSR223 PreProcessor and Groovy language, take a look at the following JMeter API shorthands:
Arguments
vars aka JMeterVariables
sampler aka HTTPSamplerBase

And please stop posting code as images it's not very polite / disrespect to the community.

How to throw an Apache JMeter keyless token into a variable?

this works, but how can I ignore the quotation marks in the form of my token "token"
i don't want him to get the quotation marks
I would use Boundary Extractor
Put Left and Right Boundary as " and you will get the value
Allows the user to extract values from a server response using left and right boundaries. As a post-processor, this element will execute after each Sample request in its scope, testing the boundaries, extracting the requested values, generate the template string, and store the result into the given variable name
You need to provide the Template and specify the capturing group (in your case it will be 1)

Extract multiple tag values in One Jmeter Regular Expression

I have a response which have multiple values which need to pass in the next request. How can I right a single regular expression to capture that values and pass those to next request.
<id>583839</id>
<Clientno>543</Clientno>
If you configure the Regular Expression Extractor as follows:
textual representation of the settings:
Variable: DATA
Regular Expression: (?s)<id>(\d+)</id>.*<Clientno>(\d+)</Clientno>
Template: $1$$2$
You will be able to access the extracted values as:
${DATA_g1} - for 583839
${DATA_g2} - for 543
More information:
Using RegEx (Regular Expression Extractor) with JMeter
Apache JMeter - Regular Expressions
Perl 5 Regex Cheat sheet
This is simple. You can use a regular expression extractor for this.
Just add 2 regular expression extractor config elements to the sampler from which you would want to extract data. Specify the below expressions in them and specify a relevant variable name. The template should be $1$ in both elements.
<id>(.+?)</id>
<Clientno>(.+?)</Clientno>
The above will provide you variables with the data you need.

Jmeter beanshell Encounter ";"

I am trying to execute beanshell script in jmeter for a URL parameter value. I have the following:
${__BeanShell(vars.get("query").replaceAll(" ","%20"))}
The jmeter console outputs this:
Caused by: bsh.ParseException: In file: inline evaluation of: ``vars.get("query").replaceAll(" ";'' Encountered ";" at line 1, column 33.
I can't figure out what the problem is as the character there is a , not a ;.
You're doing something ridiculous. Encoding an URL is not only about escaping spaces, looking into URLEncoder documentation you will need to handle:
All non-Latin non-alphanumeric characters
All characters apart from ., -, *, and _
Which might be very tricky.
So you basically have 2 options:
Use JavaScript encodeURIComponent() function via JMeter's __javaScript function like:
${__javaScript(encodeURIComponent("${query}"),)}
Or use aforementioned URLEncoder from __groovy() function like:
${__groovy(URLEncoder.encode(vars.get('query')\, 'UTF-8').replaceAll('\\\+'\,'%20'),)}
Performance-wise in cases of high loads Groovy is preferred option, check out Apache Groovy - Why and How You Should Use It article for more details.
See JMetrer's functions tutorial, you need to escape every comma:
If a function parameter contains a comma, then be sure to escape this with "\", otherwise JMeter will treat it as a parameter delimiter.
In your case
${__BeanShell(vars.get("query").replaceAll(" "\,"%20"))}
Also consider using __groovy function instead of __BeanShell for better performance.
Please use below code in Beanshell PreProcessor or BeanShell PostProcessor in order to replace single space character to '%20':
String myString = vars.get("query");
String new_var = myString.replaceAll(" ", "%20");
vars.put("updated_value", new_var);
You can further use 'updated_value' variable having space replaced by '%20' in next requests.
Please refer to the JMeter Knowledge Base for more information on JMeter elements.

Extracting javascript variable and passing to next Jmeter request

The Response data look like following within Script tag
var csrfParam =
"SKtEMgZtO0H8EYHkAZIQ4tcS5bC8jKrD=y2G5Of06jgHbkNdHNleFKiXoBMC62veD";
var securityTokenName = "SKtEMgZtO0H8EYHkAZIQ4tcS5bC8jKrD";
var securityTokenValue = "y2G5Of06jgHbkNdHNleFKiXoBMC62veD";
I'm using regular expression extractor as following:
Reference name : MYREF
Regular Expression : securityTokenName ="(.+?)" securityTokenValue="(.+?)"
Template : $1$$2$
I'm access this variable in next Jmeter request to build the URL:
${MYREF_g1}
${MYREF_g2}
Expecting to get MYREF_g1 =SKtEMgZtO0H8EYHkAZIQ4tcS5bC8jKrD
and MYREF_g2 =y2G5Of06jgHbkNdHNleFKiXoBMC62veD
But THIS is not working .
Any help would appreciated!
It looks like that you're misunderstanding what groups and templates are.
As per Using RegEx (Regular Expression Extractor) with JMeter
Template. The template used to create a string from the matches found.
This is an arbitrary string with special elements to refer to groups
within the regular expression. The syntax to refer to a group is:
'$1$' to refer to group 1, '$2$' to refer to group 2, etc. $0$ refers
to whatever the entire expression matches. So, if you have in response
word “economics” and search for regular expression “(ec)(onomics)” and
apply template $2$$1$ than in output variable you will receive
“onomicsec”.
So your RegEx should look like:
var securityTokenName = "(.+?)"; var securityTokenValue = "(.+?)";
So
securityTokenName will be stored in JMeter Variable MYREF_g1
securityTokenValue will be stored in JMeter Variable MYREF_g2
View Results Tree Listener has built-in RegExp Tester on ResponseData tab. You can also use Debug Sampler to see what variables have been set by your Regular Expression Extractor.
You need multiline regex match. Your regex will look like this
(?s)securityTokenName="(.+?)".*?securityTokenValue="(.+?)";
A sample test plan (it uses dummy sampler from jmeter plugins, if you don't have them it will faile) is here.
This post here discusses that simply having .*? will match multiple line, but apparently it did not work. This post wast the savior.
Details are from the jmeter documentation are here.
Please note that I have removed the spaces around = to simplify my sample. Please change the regex appropriately.
