Check status of item to see if its in stock?

I want to automate node red to check and let me know when this items comes in stock:

I tried an http request node and did get a payload response in my debug, but it doesnt seem to include the entire website, just part of it. What gives?

I believe you need to find the value of:

<span data-event-type="product-click" class="button button--small card-figcaption-button" data-product-id="171">

You can probably use a function node and regular expression

it’s there. It’s just truncated
