Ralph, can you help with a problem relating to this chunk of HTML please?
I found my place in the tree by finding all the <h2 lines, selecting the
one for area7, then selecting the parent with
section = area_lists[13].parent, which begins
<section aria-labelled by.....
I need to find the value of the class attribute, which could be
"marine-card" or "marine-card warning" but
print(section.contents) starts with the <h2 line, and
print(section.contents[0] prints only a blank line.
I tried converting the content to a list of lines, but again, it started
with the <h2 line.
Thanks for your help.

Hi Graeme,

Look particularly in area-labelledby area7
class="card-content"
class=forecast-block"
etc.
Looking at the HTML, as soon as you click on a lower level tag,
the == $0 disappears
I'm not sure what clicking you mean, but the <section> for 'area7' looks
filled out in the HTML returned by the web server to me.
