[mueller.de] wrong price detection

[Nisbo]

I try to monitor this shop page
https://www.mueller.de/p/purina-gourmet-gold-feine-komposition-mit-rind-huhn-949377/

But changedetection reports the wrong price (0,69 instead of 0,58)

Mainpage

Preview --> Screenshot

I am using this options:

• Re-stock & Price detection for pages with a SINGLE product
• WebDriver Chrome/Javascript

Portainer Stack

version: '2'

Any idea how to fix this ?

they have the wrong price in their ld/json machine data that we are reading from their content...

Thx for your answer, but maybe we can find a work around.

The price in the html code is in these tags

<span class="h1 h2-desktop-only product-price_component_product-price__main-price-accent__zHz13" data-track-id="priceContainer">0,58 €</span>

or 

<span class="h1 h2-desktop-only" data-track-id="priceContainer">66,95 €</span>

So with REGEX this should be possible to get the price with:

<span[^>]*data-track-id="priceContainer"[^>]*>\s*([\d]{1,3}(?:[\.,]\d{2})?)\s*€

But I have no clue how to configure this in changedetection.

What about do a source monitor

source:https://thesite.com/page.html

then put just span.h1 as the filter? could work

Thx, looks good so far. 👍
I used

/data-track-id="priceContainer">([\d.,]+)\s*€/

in the Extract text field

For the search function

General Tab

Filters & Triggers

But how do I get the price into the price column on the mainpage ?
