The page I am testing has the following code:

<span class="highlighted">...</span>
...
<span class="selected highlighted">...</span>

I was able to locate any of these <span>s in the browser with this XPath expression:

//span[contains(@class, 'highlighted')]

So I tried using that in my Python code:

expect(page.locator("//span[contains(@class, 'highlighted')]")).to_be_visible()

but Pytest complained that the element was not visible. When I printed page.content(), I didn’t see the highlighted attributes. I suspected that they might have been dynamically generated (unless I misunderstood how page.content() was supposed to work).

I was able to select the parent node of these spans both by XPath and via Playwright, but for some reason these elements couldn’t be selected.
