Apache crashes

There are one or two serious (but ridiculous) sudden-death errors on PHP/Windows that I've seen in the past. Not strictly with import_html, but just as seemingly random (albeit replicatable) causes.

Believe it or not, I've usually been able to solve then by finding the offending point in the code and inserting:
/* this comment does nothing, but stops PHPx.x on Windows from borking */

... yea.

You'll probably see a line in your apache error log saying 'Error #659989' (I can't recall the actual number) and a search on that will throw up some hair-pulling but no actual answer.

So, turn on debugging for import_html (uncomment the debuglevel line at the top of the module)
Try again, and note how far it got.

Place die('got this far OK '.__FILE__ .':'. __LINE__); in the code just after that, then shift it down a few lines, repeat until apache dies.
You will find a piece of innocuous code there. possibly to do with DOM manipulation, but possibly totally harmless.

Scream.

Exactly which distro did you get the PHP from? XAMPP/bin/exe/zip/other? I've got, um, 5.0.4 on a windows XP box, but may try an alternate if you can refer to the exact thing.
You may find it worthwhile to try a slightly different build yourself.

Fair question, but don't worry.
The library directory gets pushed into the include path somewhere really early on.
You'd see bigger errors if that was the problem.

Ah well, good going on the debug!
I've never succeeded in getting a real debug environment going.
Well, actually, I have, several times, but it always took me longer than it should and I could never remember how to do it again the next morning...

Anyway. It would appear that it is again something with the XML engine. It's changed several times through minor PHP versions already, and I've tried to accomodate it (as you can see in that lib :-{
I can say that PHP 5.1.2 (Ubuntu) doesn't have the same issue, but that probably doesn't help you :(

Sorry, to track that down would mean getting friendly with the horrible beast that is PHP XML support.
Things to looks for would be - what is the node type of that $xmlnode? It seems that this code allows it to be an xmlDocument itself, and that may not be allowed.
... Actually I see that in your data! That's handy!

So, the Node is itself the root Document. Hm.
(This also means that there was some problem with the page parsing, but we'll soon see.)

I'd try adding

    if ($xmldoc == $xmlnode) return $xmldoc->saveXML($xmlnode->firstChild);

just before the problem

... That may stop fatal crashes, but may also return slightly wrong results.

Pure guesswork for me.
I gotta go to bed. Have fun!
