JMeter - Extract Form's action attribute using Regular Expression Extractor

Question

In JMeter, using a post processor Regular Expression Extractor, i want to extract the form's action attribute. What regular expression should i use?

Answer 1

You should not be using regular expression to parse HTML, go for XPath Extractor instead and use query like

//form/@action

See XPath Tutorial and Using the XPath Extractor in JMeter for more details.
