Runnig the following script (php -q domtest.php), you will get a Windows System Error when the script ends.
The Error depends on the internal size of the xml document.
If the 'for' is of 100 iterations, the error no happen.
(I'm using the Windows compilation downloaded from php.net. Same problem in version 4.3.0)
domtest.php:
<?
if (!extension_loaded("php_domxml")) @dl("php_domxml.dll");
$domR=domxml_new_doc('1.0');
$nItinerario = $domR->create_element("itinerario");
for ($i=0; $i<400; $i++) {
$n=$domR->create_element("HH");
$n->append_child($domR->create_text_node('long long long long long long long long long long long long'));
$nItinerario->append_child($n);
}
$domR->append_child($nItinerario);
//$xml=$domR->dump_mem();
//echo $xml;
?>
