note 22506 added to ref.domxml

I have one huge problem when i use XPath implementation. My operative sysem says that PHP script tries to get some unreachable memory. It occures when i parse an XML document with help of XPath. I found that it depends on file size. What can i do? -- http://www.php.net/manual/en/ref.domxml.php http://master.php.net/manage/user-notes.php?action=edit+22506 http://master.php.net/manage/user-notes.php?action=delete+22506 http://master.php.net/manage/user-notes.php?action=reject+22506
