Extract Javascript From Html Response In Karate

I need help here. I have a POST request which returns response with a HTML response and this HTML response contains javascript inside it. I need to extract text/javascript where it

Solution 1:

Use a Java regex:

* defpattern = java.util.regex.Pattern.compile('checkout =.+(\\{[^;]+)')
* defmatcher = pattern.matcher(response);
* assert matcher.find()
* defbody = matcher.group(1)

We will be adding this as a karate.extract() helper in 0.9.6.RC3 onwards: https://github.com/intuit/karate/issues/1094#issuecomment-616059232
