Hello,
Just to let anyone know who has been following this thread, I have
fixed the problem, and it turns out to be completely unrelated to my
original 2 hypotheses. I had narrowed the problem down to this loop:
for (var j = 0; j < sites.length; j++) {
InfoWinJeremy += sites[j].textContent + "\<br\>";
}
My original hypothesis was that there was something wrong with the XML
Element parsing, but that turned out to be unrelated. The XML parsing
in this loop is absolutely fine. The issue is actually more related to
what Larry had suggested: "what is sites.length?". The problem is that
there were certain instances in which sites.length, a dynamic
variable, was zero. This is because there were no XML Element <site>
entries for some of my <Placemarks>. This was causing the loop to
increment from 0 to <0 (obviously not possible) and causing an error.
Javascript, in its infinite elegance was simply skipping the loop and
continuing on to the next valid statement. No error, no html generated
inside this infernal loop.
I simply ensured that there was at least one <sites> element for each
<Placemark> in the KML file and everything works totally fine. This is
sort of a logical error that most seasoned programmers would most
likely not make, but I am not a seasoned programmer (although I did
catch this one on my own!). Thanks to Larry and Mike, and I hope this
can help others in the future...
