How to setup to detect element in a page?

[rice818]

I am a newbie here, just want to setup a detection for certain supermarket in Australia when the promo 1/2 price

Like this item, the item will show a 1/2 bage on the product like this

the element is like this
https://www.woolworths.com.au/shop/productdetails/623034/coca-cola-zero-sugar-soft-drink-bottle

However, tried everything but not working, any expert here know how to detect 1/2 price?

That's an embedded image, not text. Why don't you just use the actual product price to detect the change? It shows something like $2.05 was $4.05. Use the xpath on these element to detect the change and output the new price to send the notification.

Thanks for your reply, however the price detection was not working, don't know this because of the price is divided into two part.

That's why want to detect the image price tag much easier.

Something like this using xpath..
"/html/body/ar-partial/ar-product-detail-container/section/div[1]/div[2]/div[2]/ar-product-detail-panel/section/div/div[2]/ar-product-price/div/div[1]/concat("$",div/div/span[2],".",div/div/div/span[2],div[2])"
This is the output I got using the above xpath: $2.30 Was $3.85

During my test, it kept failing to load the web page, but I found a solution to this problem. It is to use Advanced Request Headers as shown here.
