Hi All,
I am receiving below response in one of the API. We need to parse below HTML Content and extract only Status and progress Info.
Expected output is:
status = Confirming subcription...
Progress = Your browser has JavaScript disabled. <i>To confirm a subscription via this page, your browser must have JavaScript enabled. To confirm your subscription without enabling JavaScript in your browser, use an Amazon SNS client to call ConfirmSubscription with the <code>Topic</code> and <code>Token</code> parameters supplied in the confirmation message.
How can I parse the given HTML and extract required info. Thanks in advance.
Thank You

Looks like you are receiving html, css, and some script in the response... so because of that, you can try a Regular Expression...
var response = <The response you are getting from the API>
var result = response.match(<h2 id="status">(.*)</h2>);
gs.log(result[1]);
This will grab the status, then just do the same thing just do the same for the progress text.
