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.

I could not get the XPath Extractor to work; from reading the JMeter log, it looks like the XPath Extractor will not work if the html being parsed is not well-formed xml.

But, I was able to extract the form action using a CSS Selector Extractor with the following values:

CSS Selector expression: form
Attribute: action
Match No. (0 for Random): 1

You can tick the "Use Tidy (tolerant parser)" option to get around this – Shawson Apr 17 '23 at 10:34
