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.

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.
