Response text from sampler is :
<input type="hidden" name="pid" value="PID_1498281212971253461">
The basic reg ex extractor mentioned for most of the correlations is (.+?). I have read the basics of the reg ex by googling and trying to understand reg ex better Base on the understanding, I tried Reg Ex (2nd Reg Ex) which I am not getting any matches.
Extractor1: RegEx1
Extractor2:RegEx2
Pls. help me in understanding. Appreciate your help.
This is my first post in any channel, pls ignore any comm errors.
You're almost there, your regular expression is basically missing a repetition meta character to wit +. In its current state it will match only something like <input type="hidden" name="pid" value="PD_1">
So you need to add + sign to the end of each character classes groups and your regular expression should start working as expected

When it comes to parsing HTML responses using regular expressions is not the best option, you might want to consider using CSS/JQUery Extractor instead
You could use the XPath Extractor instead, will be simpler, here is the XPath to use
//*[#name='pid']/#value
Please make sure, you check the options, Use Tidy and Quiet in the XPath Extractor

<input
name="formToken" type="hidden"
value="19225544fb878c9a8c77dafdfe616454a13e3c96"
/>
above is the line having lot of space in between. i want to extract value using regular expression in Jmeter. so please help me for regular expression to extract.
Try doing a find on this regex:
value="([^"]+)"
And then access the following in the template:
$1$
See the demo link below for an example of this working.

Be informed that using Regular Expression Extractor for parsing HTML is not the best idea, I would recommend going for CSS Selector Extractor instead, the relevant configuration would be as simple as:
Selector: input[name=formToken]
Attribute: value

Try with the following Regex:
value="(.+?)"
I want to get viewstates from diffent types.
One is in html :
id="j_id1:javax.faces.ViewState:0" value="GKILT9kVeCjgGmRutjLtzOO840X+LyZk" autocomplete="off" />
The other is in xml :
id="j_id1:javax.faces.ViewState:0"><![CDATA[GKILT9kVeCjgGmRutjLtzOO840X+LyZk]]></update>
When I run my regular expression, the result array is diffrent. The One result is array[1][3] the other result is array[1][4]
My Regex like this :
id="j_id1:javax.faces.ViewState:[\d]+"(><!\[CDATA\[(.+)\]\]|\svalue=")(.+)(\]\]><|"\sautocomplete)
How can I get result same array data?
Thank you.
If you want a single Regular Expression to work for both scenarios you can use something like:
(?:(id="j_id1:javax.faces.ViewState:(\d+)" value="(.+?)" autocomplete="off" />)|(id="j_id1:javax.faces.ViewState:(\d+)"><\!\[CDATA\[(.+?)\]\]></update>))
This will match ViewState value from both inputs as it evidenced by the RegExp Tester mode of the View Results Tree listener.

<input type="hidden" name="_csrf"
value="40ea7f46-799b-4ca0-b8cd-4adfba082aed" />
Above is the token I am getting in the request output. I am unable to replace this with a regular expression in Regular Expression Extractor of Jmeter.
<input type="hidden" name="_csrf" value="(.+?)" /> is not working.
Please help.
If your input actually contains a newline character, then you need to account for that in your regex. Furthermore, better be explicit about the valid characters in your regex, .+ is rarely a good thing:
<input type="hidden"\s+name="_csrf"\s+value="([^"]+)"\s*/>
you have to be careful with the spaces/newlines.
try with following simple regex:
value="(.*?)"\s/>
If it matches more than one element, to add uniquness, you can add name attribute in the regex as follows:
name="_csrf"\s+value="(.*?)"\s/>
This is another evidence for not using regular expressions to parse HTML as they are very fragile and sensitive to minimal markup changes. The more robust and resilient solution is using CSS/JQuery Extractor or XPath Extractor instead.
The relevant CSS Expression is input[name=_csrf], use value as "attribute"
The XPath query to get the value is //input[#name='_csrf']/#value
See How to Load Test CSRF-Protected Web Sites guide for detailed information on bypassing XSRF protection in JMeter tests
Code is:
<input name="__RequestVerificationToken" type="hidden" value="Yekn8BJNbXaydRs8yq1GEmDogsFoSh8AGyOKmjLn0zFvhmADPYrqU43/foLoEzJk4yEeNSg78pCIJh6uxuyWf9foM7VsZayC2trOXwUA2hyUWSAf9mBC8vN60ccAVki37fC1LNHhAlDkthgmsM3WNxJwvVGWMj2TMqoONGI0aj5b2hJkQMMClKx0zhthqtD8" />
My Jmeter config. is given below as screenshot :
What is incorrect I did here :( It is not logging & giving error : Object moved to here
In your regular expression extractor, your regular expression needs to be
<input name="__RequestVerificationToken" type="hidden" value="(.+?)"
instead of what you have now. It should work once you change that.
This is why you shouldn't use regular expressions for parsing HTML: one of the reasons is that HTML-oriented regular expressions would be very fragile and sensitive to any line-break, space, tags order, etc.
So the options are:
CSS/JQuery Extractor. Relevant config would be:
CSS/JQuery Expression: input[name=__RequestVerificationToken]
Attribute: value
XPath Extractor. Configure it as follows:
XPath Expression: //input[#name='__RequestVerificationToken']/#value
if your response is not XML/XHTML-compliant you'll also need to check Use Tidy (tolerant parser) box
I have a string in a jmeter response that has 5 values that I am trying to parse into separate variables. Does anyone have any guidance on how I may achieve this? Or is there a better post processor I should be using?
<a role="button" aria-label="Application RANUM20770" href="javascript://" onclick="changenew('ajLQ6VdK5xA3$pyWV$pII4Imx2WoN$p6OMtXEapDOiKzHYLh', 'aH$sRRQGllagYsNakUyuWhv6yV7x3q1S6HfC8Z$ptwPdTMo', 'arfpB11JptWMaFvd2xwkJyNlgHL$spkcuHbJhank$s6DONv', 'aQ877kS6ozZdrGgAFxb6mqEnzCFa09$sVWL$s68yj0rmcwr', 'a4oVRp9kcV4iber3oJSH2xQr3F6XsGB4DpCxgrMNI9y7U', 'no')" ><img src="/tm/images/idoc.gif" alt="Application RANUM20770" border=0></a>
I am using regex extractor to pull the values, for some reason the results aren't consistent. Sometimes the 2nd value pulls fine and other times it doesn't- without me changing anything.
Below are the regex expressions I am using :
${h_docname}" href="javascript:\/\/" onclick="changenew\('(.+?)',
'${p_vchnum_v}', '(.+?)', '
'${p_vchnum_v}', '(.+?)', '${p_ssn}'
'().+?', 'no'\)" ><img src="\/tm\/images\/idoc.gif" alt="Document ${h_docname}"
- name="vchdoctype" value="(.+?)">
Any help is greatly appreciated.
JMeter uses Perl5-style regular expressions, hence try the following configuration of the Regular Expression Extractor:
Reference Name: anything meaningful, i.e. value
Regular Expression: changenew\('(.+?)', '(.+?)', '(.+?)', '(.+?)', '(.+?)', 'no'\)
Template: $1$
This will result in variables like:
value=ajLQ6VdK5xA3$pyWV$pII4Imx2WoN$p6OMtXEapDOiKzHYLh
value_g=5
value_g0=changenew('ajLQ6VdK5xA3$pyWV$pII4Imx2WoN$p6OMtXEapDOiKzHYLh', 'aH$sRRQGllagYsNakUyuWhv6yV7x3q1S6HfC8Z$ptwPdTMo', 'arfpB11JptWMaFvd2xwkJyNlgHL$spkcuHbJhank$s6DONv', 'aQ877kS6ozZdrGgAFxb6mqEnzCFa09$sVWL$s68yj0rmcwr', 'a4oVRp9kcV4iber3oJSH2xQr3F6XsGB4DpCxgrMNI9y7U', 'no')
value_g1=ajLQ6VdK5xA3$pyWV$pII4Imx2WoN$p6OMtXEapDOiKzHYLh
value_g2=aH$sRRQGllagYsNakUyuWhv6yV7x3q1S6HfC8Z$ptwPdTMo
value_g3=arfpB11JptWMaFvd2xwkJyNlgHL$spkcuHbJhank$s6DONv
value_g4=aQ877kS6ozZdrGgAFxb6mqEnzCFa09$sVWL$s68yj0rmcwr
value_g5=a4oVRp9kcV4iber3oJSH2xQr3F6XsGB4DpCxgrMNI9y7U
So you will be able to use:
${value_g1} - for 1st variable
${value_g2} - for 2nd variable
etc.
