PHP processor for processing xml+xslt?

Question

PHP

There is an initial xml store (or a php script that generates an xml catalog from the database)
and xslt (generated in php dynamically depending on the parameters passed to the script)
The essence of the problem: if an xml file is processed up to 10MB, then everything is fine.
but on xml ~ 17+ mb falls due to lack of memory. (on the server I set the maximum script processing time and the maximum possible allocated memory, the problem was not solved)
I do the processing through xsltprocessor

$xml = new DOMDocument;<br>
$xml->load('http://site.ru/yandex_market.php');<br><br>
$xsl = new DOMDocument;<br>
$xsl->load('http://mysite.ru/manager/template.php?a='.$_GET['a'].'&o='.$_GET['o'].'&c='.$_GET['c']);<br><br>
// Configure the transformer<br>
$proc = new XSLTProcessor;<br>
$proc->importStyleSheet($xsl); // attach the xsl rules<br><br>
echo $proc->transformToXML($xml);<br>

if run through a similar script, it swears at xslt_create (), although xml, xlst modules are connected in phpinfo

<?php<br><br>
// Разместить новый XSLT-процессор<br>
$xh = xslt_create();<br><br>
// Обработать документ<br>
if (xslt_process($xh, 'sample.xml', 'sample.xsl', 'result.xml')) {<br>
print "SUCCESS, sample.xml was transformed by sample.xsl into result.xml";<br>
print ", result.xml has the following contents\n<br>\n";<br>
print "<pre>\n";<br>
readfile('result.xml');<br>
print "</pre>\n";<br>
}<br>
else {<br>
print "Sorry, sample.xml could not be transformed by sample.xsl into";<br>
print "result.xml the reason is that " . xslt_error($xh) . " and the ";<br>
print "error code is " . xslt_errno($xh);<br>
}<br><br>
xslt_free($xh);<br><br>
?><br>

Well, I don't know if this will help?
In general, the essence of the task is to replace the links in the offer/url (see yml ) with your own.

Without going into the wilds of the php code, I can only remind you of one thing - in case of lack of memory (the DOM is bold, it does not fit), you need to change the parser to SAX
