Extracting PostBack value in Jmeter - regex

I want to extract the PostBack password value in Jmeter but all my efforts so far are returning null.
The value needs to be extracted after clicking a button that sends this request:
javascript:__doPostBack('ctl00$ctl00$ContentPlaceHolder2$ContentPlaceHolder4$lbAddRecord','')
A dialog appears with the password.
Using google developer tools, I can see the full response with the info I need:
<span id="txtPassword" TextMode="Password">Rq0&t*Y32H</span>
When I run the script in Jmeter, the response only contains:
1|#||4|9|pageRedirect||%2fWeb%2f|
I tried the following to extract the password value:
regular expression extractor:
reference name: password
regular expression = <span id="txtPassword" TextMode="Password">(.+?)</span>
template: $1$
match no: 1
default value: null
xpath extractor:
reference name:password
xpath query: .//*[#id='txtPassword']
default value: null
How do I have to change my extractor query to get the password value?

You problem comes from the request that precedes the one you're trying to extract data from.
So investigate what is missing in it (headers, cookies, request parameter) that explain why you don't get the correct content.

Extract a value from actionlink html response body - JMeter

I have a response body from one http request and I have to extract all the values and as input to another http request
<a class="action-link"
regionName="region name"
jName="a country"
alertID="179"
onclick="showDetail(this)"> Snapshot- v4 (Active)
</a>
i tried with regex like
created a post processors -> regular expression extractors
Apply to -> Main Sample Only
Field to check -> Body
Name of created variable -> regionNameVariable
Regular Expression -> <a class="action-link" regionName=(.*?)
and passed the value as ${regionNameVariable} in the next request.
But It is not working.
Can someone suggest the correct way of doing this.
Be aware that using regular expressions for parsing HTML is not a very good idea, consider using CSS Selector Extractor instead, the relevant configuration would be:
Name of created variable: regionNameVariable
CSS Selector Expression: a[class=action-link]
Attribute: regionName

How to Use the CSS/JQuery Extractor in JMeter
Add multiple Regular expression extractor to extract each values
For example to extract the 3rd group in regex of Region Name(You can write better Regx if you have better idea)
Like Wise Add Regex for jName and alertID
(jName)(=)\"(.+)\"
(alertID)(=)\"(.+)\"
Then Pass on the Reference name as user variable in your next http request.as ${regionName} and so on.
If you want to do it in the same Regex post Processor. Please refer How to extract multiple values with a regular expression in Jmeter

Need a regexr to fetch the multiple data

I need a regrex to get the value in the below format
Code=ABC&cellNo=314&payType=0&transmission=MANUAL&vendorId=ET&toggleSelctd=0&uniqueId=39
This is a sample code is attached in the below screenshot
but however the regrex which i have created fetches data for one value but i need the same in the above format, for example below are the regrex.
name="cellNo" type="hidden" value="(.+?)" value="(.+?)
name="transmission" type="hidden" value="(.+?)"
Thanks
Don't use regular expressions to parse HTML. JMeter offers CSS/JQuery Extractor for fetching data from the HTML pages so you should be able to extract the required values using the following configurations:
For MANUAL:
Reference Name: anything meaningful, i.e. transmission
CSS/JQuery Expression: input[id=transmission]
Attribute: value
For 314
Reference Name: anything meaningful, i.e. CellNo
CSS/JQuery Expression: input[id=CellNo]
Attribute: value
See How to Use the CSS/JQuery Extractor in JMeter article for more information.
I think response markup is a little bit flaky as HTML input cannot have 2 name and 2 value tags, I would recommend using JMeter's HTML Assertion or online HTML Validator to check response data and raise issues on validation errors.

Unable to extract Session ID Jmeter?

Am unable to extract Session ID ? Please find the details below
Response : link type="text/css" rel="stylesheet" href="/dm-web/javax.faces.resource/style.css.xhtml;jsessionid=107A7FE4C426D95B24A9094AE4E801DE?ln=css"
Regular Expression :
Refrence Name : Corr_sessionID
jsessionid="(.+?)"?ln=css" />
Template: $1$
match No: 1
Default Value: EAE8FABC3D2560786752A48AC890D1D0
Passing In the URL :- /dm-web/javax.faces.resource/style.css.xhtml;jsessionid=${Corr_sessionID}
Your regex should look like this jsessionid=([0-9A-Z]+)\?ln=css, since you need to escape the ? character and should not add the " characters between your expression.
You can use HTTP Cookie Manager to automatically take care of the JSESSIONID cookie.
If you need the cookie value for some reason, you could do the following:
add CookieManager.save.cookies=true line to user.properties file
restart JMeter
Now cookies which live in the HTTP Cookie Manager are available as JMeter Variables so you can refer to JSESSIONID Cookie value as simple as:
${COOKIE_JSESSIONID}

Jmeter Regular Expression Extraction

Could someone help me in getting the value "1237857346" from the following using regex or any other way I could get the value "1237857346" in from HTML in JMeter.
<select class="card_account" name="existing__account">
<option value="" disabled="disabled">Card Number</option>
<option value="1237857346" selected="selected">************4567</option>
</select>
Little bit of background. I am using JMeter and trying to extra the value "1237857346" to pass it in the next request.
It is not very good idea to parse HTML using Regular Expressions as it evidenced by the famous Stack Overflow answer
I would suggest switching to XPath Extractor instead. Add the XPath Extractor as a child of HTTP Request sampler which returns that select and configure it as follows:
XML Parsing Options: tick Use Tidy box. It may not be necessary but if your server response is not XML/XHTML compliant you'll get nothing
Reference Name: anything meaningful, i.e. value - it will be the name of the variable holding extracted data
XPath Expression: //select[#class='card_account']/option[#selected='selected']/#value - it will take
select having class = card_account
option with selected = "selected"
value attribute of the above option
and store it to "value" variable. You will be able to refer to it as ${value} where required.
See following material for further reference:
XPath Tutorial
XPath Language Specification
Using the XPath Extractor in JMeter
You can use the following regex:
<option[^<]*>Card Number</option>\s*<option[^<]*?value="(\d+)"
The value will be in group 1 ($1$), which is exactly what you need.
See demo
In case the are always 12 asterisks (that can be matched with \*{12}) in the <option> node value, you'd can use:
<option[^<]*value="(\d+)"[^<]*>\*{12}\d+</option>
See another demo.

How to properly use xpath & regexp extractor in jmeter?

I have the following text in the HTML response:
<input type="hidden" name="test" value="testValue">
I need to extract the value from the above input tag.
I've tried both regexp and xpath extractor, but neither is working for me:
regexp pattern
input\s*type="hidden"\s*name="test"\s*value="(.+)"\s*>
xpath query
//input[#name="test"]/#value
The above xpath gives an error at the Xpath Assertion Listener .. "No node matched".
I tried a lot and concluded that the xpath works only if I use it as //input[#name].
At the moment I'm trying to add an actual name it gives the error .. "No node matched".
Could anyone please suggest me how to resolve the above issue?
Please take a look at my previous answer :
https://stackoverflow.com/a/11452267/169277
The relevant part for you would be step 3:
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.select.Element;
String html = prev.getResponseDataAsString(); // get response from your sampler
Document doc = Jsoup.parse(html);
Element inputElement = doc.select("input[name=test]").first();
String inputValue = inputElement.attr("value");
vars.put("inputTextValue", inputValue);
Update
So you don't get tangled with the code I've created jMeter post processor called Html Extractor here is the github url :
https://github.com/c0mrade/Html-Extractor
Since you are using XPath Extractor to parse HTML (not XML) response ensure that Use Tidy (tolerant parser) option is CHECKED (in XPath Extractor's control panel).
Your xpath query looks fine, check the option mentioned above and try again.
