This is a simple tool to fetch a page using selenium and allowing access to its wait parameters.

sudo apt install python3-full mercurial
hg clone https://hg.kewl.org/pub/sget
cd sget

This web page loads a page of temporary content and after a delay it will reload.

The reloaded content contains a subset of the full content and requires scrolling to reveal it all.

Fetch the temporary page

py sget.py "https://www.deckenmalerei.eu/e8a3bf28-6365-42fe-a4d3-41608ed870e8" d0.html

Fetch the reloaded page

py sget.py "https://www.deckenmalerei.eu/e8a3bf28-6365-42fe-a4d3-41608ed870e8" -d10 d10.html

Compare temporary and reloaded

Fetch the page again but this time wait for the reloaded content based on the reloaded tag attribute

py sget.py "https://www.deckenmalerei.eu/e8a3bf28-6365-42fe-a4d3-41608ed870e8" -b XPATH -v "//div[@class='dataPage']" dataPage.html

Scrolling the page down to reveal more images is not a function of sget.
