JMeter - Convert Unicode Hex Char to "normal string" - jmeter

I automating a script in which I am using a regular expression to extract the path of the next HTTP request, the problem is that the value matched with the regular expression contains things like /, so I need to convert that into/, in order to be able to send the path in a valid format.
I expect that it should be possible to do that using a PostProcessor, but I am not sure of how it should be scripted.
Thanks in advance.

If they are the proper HTML/XML-encoded characters, you can use inline function __unescapeHtml, e.g.:
${__unescapeHtml(/)}
The function above uses Apache's StringEscapeUtils under the hood, so you can call it from BeanShell post-processor:
import org.apache.commons.lang3.StringEscapeUtils;
vars.put("myvar", StringEscapeUtils.unescapeHtml4("/"));
The same library has a bunch of other functions, that may be useful, depending on what you are decoding from, for example:
import org.apache.commons.lang3.StringEscapeUtils;
vars.put("myvarxml", StringEscapeUtils.unescapeXml("/"));

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

Jmeter- How to pass Comma separated String as 1 value through parametrization

From a csv file, I need to pass
224,329,429
as a single value to one of the parameter in HTTP request.
I have parameterized using CSV data config. But, only 224 is getting passed.
I want 224,329,429 to be treated as a single value.
Please let me know how do I achieve this. Should I change anything in CSV config or CSV file to make this work?
Just use __StringFromFile() function instead of using CSV Data Set Config.
The __StringFromFile() function reads next line from the file each time it's being called so it seems to be a lot easier to stick to it for particular your scenario.
The syntax is as simple as ${__StringFromFile(/path/to/your/file.csv,,,)} and the function can be used anywhere in the script, i.e. directly in the request parameter section.
See Apache JMeter Functions - An Introduction to get started with the JMeter Functions concept and comprehensive information on the above and other JMeter functions.
You should change your delimiter to a not used character e.g. #
In that way you will be able to get full line for every request
Use ${__FileToString(dummy.csv,,payloadvar)} function. It makes the file independent that mean you can use any file extension example: .txt, .csv, .excel etc..
Just keep the string in dummy.csv and it will fetch the whole string.
benefit of using this function is, it will not consider comma's so in case your string has comma separated values then this is the best option.
Just use %2C in the place of comma.

How to extract jmeter response value

I did read few responses but my regular expression extractor is not working.
Mine is a simple case where this is my response
token.id=AQIC5wM2LY4Sfcz4cOT2RrremxWJmM3llZmPl6k0bP_r5D4.AAJTSQACMDUAAlNLABQtNDI1OTg4NzgxODg5MDM1ODU2NQACUzEAAjI3
I am trying to grab the value using this expression
token.id="(.*?)"
which is not saving the value into the variable i assigned. My next request when trying to use the value fails since its not grabbing it.
Can someone let me know what exactly is missing. thanks.
There are few problems with your regular expression:
You need to escape dot between "token" and "id" with backslash as it is a special character. See Literal Characters article for more information.
You don't need the quotations marks as your response doesn't contain them (does it?)
So your regular expression needs to be amended as token\.id=(.*) (however I would rather go for something like token\.id=(\w.+)
You can use View Results Tree listener in "RegExp Tester" mode to test your regular expressions directly against response without having to re-run the request.
See Regular Expressions JMeter documentation chapter and How to debug your Apache JMeter script guide for extended information on the above approaches.

Jmeter - How Can I Replace a string and resend it?

I'm trying to create a script that will take a URL out of a response and send it out again.
Using the regular expression extractor I've succeeded in taking the wanted URL, but it holds "&" so naturally when sending it out the request fails.
Example:
GET http://[ia-test01.inner-active.mobi:8080/simpleM2M/ClientUpdateStatus?cn=WS2006&v=2_1_0-iOS-2_0_3_7&ci=99999&s=3852719769860497476&cip=113-170-93-111&po=642&re=1&lt=0&cc=VN&acp=&pcp=]/
I'm trying to replace the "&" with a "&".
I've tried: ${__javaScript(${url}.replace("&","&"))}
But it did not work. I've tried the regex function as well- the same.
I'm not sure the IP field in the request supports the us e of functions.
I'm currently trying to use the beanshell post-processor. But I'm pretty sure there is a simpler solution I'm missing.
Not sure what you're trying to get by replacing & with & however will try to respond.
First of all: given multiple & instances you need to use replaceall function, not replace
Second: replace / replaceall functions take a RegEx as parameter, so you'll need to escape your &
If you're trying to substitute URL Path in realtime, you'll need Beanshell Pre Processor, not the Post Processor
Sample Beanshell Pre-Processor code
import java.net.URL;
URL myURL = sampler.getUrl();
String path = myURL.getPath();
String path_replaced = path.replaceAll("\\&", "&");
vars.put("NEW_PATH", path_replaced);
After that put ${NEW_PATH} to "Path:" section of your HTTP Request.
Hope this helps.
Solution with less code:
Install the Custom JMeter Functions plugin
Use the following syntax
${__strReplace(ImAGoodBoy,Good,Bad,replaceVar)}
‘ImAGoodBoy’ is a string in which replacement will take place
‘Good’ is a substring to be replaced
‘Bad’ is the replacement string
‘replaceVar’ is a variable to save result string

Thank a lot. However, i see from a recent experience that to replace a character that is actually a RegExp special character, like \ " ( ) etc, you need to put 3 backslashes and not 1, not 2. This is weird.
so you write
var res = str.replaceAll("\\\\u003c", "<");
to replace \u003c with <

help in storing a value and calling a variable in jmeter request using regular extractor

my soap/xml response looks like below:
<Account><Accountnumber>1234<Description>savings</Account><Account><Accountnumber>1235<Description>Savings1</Account>
I would like to store accountnumbers in a variable or array and would call it in another soap xml request in jmeter for knowing their details. can somebody help me how i can store and how i can call that variable ? I am new to Jmeter.
Thanks in advance.
If the account numbers are static, you're better off using a .csv file, as mentioned by Vance because the CSV data reader has less overhead then regex.
However, if you want dynamic data, it's very easy to do.
Download "regex coach" to help you write regular expressions. It's an amazing tool.
Attach a "regular expression extractor" as a child to your SOAP/XML request
Run the request once, to get the reponse
Copy the response into regex coach (or whatever tool you use), and write your regex. It'll look something like this: (\d+?)\D (look for any digit after the text accountNumber and stop after a non-digit)
Configure the rest of the regex. In this case, you'll want:
Apply to: Main Sample Only
Response filed to check: Main Body
Reference Name: VariableName
Regular Expression: See step 3
Match No: 1 (1st match) 0 (any match) or -1 (all
matches, useful when doing "FOR EACH
found" logic
Default Value: failed
TO use your variable account number in other requests, simply use the reference name. In this example: ${VariableName}
Reference: http://jmeter.apache.org/usermanual/component_reference.html#Regular_Expression_Extractor
You may save your data in a ".csv" file and Jmeter can read it easily through its csv data set config.
Use ${your data variable} in your scripts.
