Extract value from html tag by Regular Expression Extractor of JMeter

Question

I have a html select like below

<select id="alias" name="alias">
  <option value="">-Select-</option>
  <option
          value='100'
          data-accountnumber='2251106207001'
          data-accountholder='Ashraful'
          data-mobilenumber='01811449003'
          data-email='shadiq2@yahoo.com'>
      testBeneficiary-1
  </option>
</select>

I need a regular expression for JMeter to extract the value which is 100 of above snippet. Can anyone help me with this? Thanks in advancet

As per https://stackoverflow.com/a/1732454/2897748

You can't parse [X]HTML with regex. Because HTML can't be parsed by regex. Regex is not a tool that can be used to correctly parse HTML.

I would suggest using XPath Extractor instead.

In your case XPath Extractor should be configured as follows:

Check Use Tidy if data isn't XML/XHTML compliant, elsewise you'll get SAX Exception
Reference Name: anything meaningful, it will be the name of JMeter Variable storing XPath Expression Result. Let it be value

XPath Query:

//select[@id='alias']/option[@data-email='shadiq2@yahoo.com']/@value

The XPath query above returns "value" attribute of option which "data-email" attribute is "shadiq2@yahoo.com" of select with "alias" id.

Once extracted you will be able to refer that variable as ${value} or ${__V(value)}

See Using the XPath Extractor in JMeter guide for more details, XPath language reference and short cookbook.

+1 to your answer. And shorter xpath would look like `//select[@id='alias']//option[2]//@value` – olyv Jun 10 '14 at 18:52
what if i need to extract the `value` of the `option` that has `innerHTML` "testBeneficiary-1"? – silk_route11 Jun 11 '14 at 08:36
In that case XPath query would be `//select/option[contains(text(),'testBeneficiary-1')]/@value` – Dmitri T Jun 11 '14 at 09:05

The given html text

<select id="alias" name="alias">
  <option value="">-Select-</option>
  <option
          value='100'
          data-accountnumber='2251106207001'
          data-accountholder='Ashraful'
          data-mobilenumber='01811449003'
          data-email='shadiq2@yahoo.com'>
      testBeneficiary-1
  </option>
</select>

We can get the option value 100 using the following regex formats

Regex formats to get the value 100

<option value="">-Select-</option>\s\s\s<option\s\s\s\s\s\s\s\s\s\s\svalue='(.+)'

Note :

\s - means single space
\s\s\s - means three spaces
\s\s\s\s\s\s\s\s\s\s\s - means eleven spaces
