Parsing HTML via JMeter regexp
(3 answers)
Closed 4 years ago.
I am trying to build a regex in jmeter while working in 1 script.
The response in the previous HTTP request looks like this:
<form accept-charset="UTF-8" action="/start" class="simple_form form-horizontal" id="new_challenger" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="✓" /><input name="authenticity_token" type="hidden" value="JvOxXp/rtZ2dTOVzWqcbQENOHD7Qknws7CMy47L3RC0=" /></div><input id="challenger_step_id" name="challenger[step_id]" type="hidden" value="cEVWeUZHc3ZnSGR6dlhrSnRhd3ZLdz09LS1rOTlFS0crYitObmFMT0pOcXJ2MVZBPT0=--2baa3ff87227212cff656c4db1040680ff78ff3f" />
<input id="challenger_step_number" name="challenger[step_number]" type="hidden" value="1" />
<input class="btn btn-xl btn-default" name="commit" type="submit" value="Start" />
</form>
I need to extract the *_step_id i.e. challenger_step_id
cEVWeUZHc3ZnSGR6dlhrSnRhd3ZLdz09LS1rOTlFS0crYitObmFMT0pOcXJ2MVZBPT0=--2baa3ff87227212cff656c4db1040680ff78ff3f
I tried the below regex but its not giving me any result when I test in regexp tester in the Results Tree View.
Regex used:
challenger[step_id]" type="hidden" value=(.+?) /><input id.
Is it happening because of the "--" characters or something else?
Need some help.
Thanks,

It is a bad idea to parse html using regex.
But if for whatever reason you have to use regex in your task, use a pattern like this:
<input[^>]+id="([^"]+)_step_id"[^>]+value="([^"]*)"[^>]*>
You may need to escape (using \) some special characters, depends on how you use the regex pattern in your source code.

I have a HTML form which currently has unique id's for each input (or select) like so.
example 1
<input type="number" id="qty-a-row" min="0" max="999" autocomplete="off" value="" style="border:0px; outline:0px; display:inline-block; width:50px;" />
example 2
<select id="ps_a_row" autocomplete="off" style="width:324px; border:0px; outline:0px; display:inline-block">
each id is unique. I'm now trying to add in a name="" with the same value as every id="" found so example 1 above becomes.
<input type="number" id="qty-a-row" name="qty-a-row" min="0" max="999" autocomplete="off" value="" style="border:0px; outline:0px; display:inline-block; width:50px;" />
and example 2 becomes...
<select id="ps_a_row" name="ps_a_row" autocomplete="off" style="width:324px; border:0px; outline:0px; display:inline-block">
and so on for every id="anything" it finds.
I'm using notepad++ and with regex ticked currently trying...
Find = id="(.*)"
Replace = id="\1" name="\1"
but this is only finding some id's and duplicates all other tags it finds after the id it finds too.
The complete code for the form I'm trying to edit is here...

Find id="([^"]+)" and replace it with id="\1" name="\1" , but you shouldnt use regex for HTML manipulation. Use appropriate tools for that.
Demo
I have about 1,000 lines of html that look like this:
<input type="text" readonly value="some-value-here" class="unit size1of2" />
I am able to find all of those lines using the RegEx search of
<input type="text" readonly value="[^<]+" class="unit size1of2" />
However, I am trying to change all of them to
<input type="hidden" value="same-value-that-was-found" />
Any ideas on what I need to do to accomplish this?
In the find input of visual studio I have this expression
<input type="submit" value=(.*) />
And in the replace one I have
<input type="submit" value=(\1) a />
But for some reason instead of adding an "a" it is literally replacing the code.
I mean, I am getting this
<input type="submit" value=(\1) a />
instead of this
<input type="submit" value="Change password" a />
I am using Visual Studio 2012 Express for Web
In the replacement string, you need to use $1. \1 is for backreferences within the search pattern. You'll also want to omit the parentheses in the replacement string.
<input type="submit" value=$1 a />
To make your pattern a bit more robust you might want to use something like
<input type="submit" value=("[^"*]") />
For the pattern. Otherwise you'll get problems if you have another self-closing tag on the same line, or an input tag with more attributes.
I'm trying the pattern attribute for the first time, and I can't get it to work (my browser does support it, though).
Right now I have:
input type="text" pattern="[a-zA-Z0-9]{6}" name="formName"
The first problem is that is doesn't notify me if it's blank; the second problem is that if I do type in something, it won't accept it. I want it to accept alphanumeric characters and be exactly 6 characters is length. I tried it with forward slashes and a few other variations.
As Duikboot already pointed out, the right way to do it is:
<input type="text" name="formField" pattern="[a-zA-Z0-9]{6}" required>
The required attribute causes the validation to fail, when the field is empty.
The pattern attribute defines the regex to test against, when the field is not empty.
(Your initial pattern seems to work fine.)
More info can be found here.
This is simple enough so as not to require a demo, but nonetheless you can find one here.
Works for me here : http://jsfiddle.net/barbuslex/nR6yg/
<form>
<input type="text" pattern="[a-zA-Z0-9]{6}" name="formName" />
<input type="submit" value="OK" />
</form>
I use Google Chrome
You simply need to add the required attribute to your tag, which will notify the user if they attempt to send the form with that very field blank.
<input type="text" pattern="[a-zA-z0-9]{6}" name="formName" required>
Try this code its working perfectly
<html>
<body>
<form action="demo_form.asp">
Country code: <input type="text" name="country_code" pattern="[A-Za-z]{3}" title="Three letter country code">
<input type="submit">
</form>
</body>
</html>
Enter invalid country code and click submit button. Then You can get a message (title="Three letter country code")
Thank you for taking the time to look at my post.
I have an input tag that i need to have output-ed like so:
<input type="hidden" name="success_redirect" value="http://www.webpage.com?var1=${root/option1}&var2=${root/option2}" />
but i cant get that into my xslt document without it eventually rendering to
<input type="hidden" name="success_redirect" value="http://www.webpage.com?var1=$&var2=$" />
What do i put in the XSLT to allow me to get that value tag to output like i need it to?
Thanks!
Just use:
<input type="hidden" name="success_redirect"
value="http://www.webpage.com?var1=${{root/option1}}&var2=${{root/option2}}" />
Do note that if we want to output a '{' or a '}' in an attribute, we have to double them.
This is because these two characters have special meaning when used inside an attribute: they indicate the start and end of an AVT (attribute-value-template).
You can concatenate the parts:
<input type="hidden" name="success_redirect"
value="{concat('http://www.webpage.com?var1=${','root/option1}','&var2=${','root/option2}')}" />
