I'm afraid that didn't work. It reads the variable as empty.
As a test, I tried print_r($rss), and while it reads everything else
correctly, it shows ['description'] as an empty variable. The only ones
that it reads correctly are the ones that don't have HTML.
Knowing this, it's got to be a "problem" with rss2array. I put
"problem" in quotes, because technically I think it's the XML file
that's flawed, but there's not much I can do about that. What other way
can I parse an XML database using PHP?
