Req #44761 [Com]: DOM & Large Files

Edit report at https://bugs.php.net/bug.php?id=44761&edit=1 ID: 44761 Comment by: clicky at erebot dot net Reported by: xwisdom at yahoo dot com Summary: DOM & Large Files Status: Open Type: Feature/Change Request Package: Feature/Change Request Operating System: Windows XP PHP Version: 5.2.5 Block user comment: N Private report: N New Comment: The DOM extension is meant explicitely to handle small XML files as it requires a copy of the file being processed and a large number of objects be kept in memory (this is also true for the SimpleXML extension which is based on the same underlying parsing library). If you need a faster alternative, I'd suggest you take a look at the XMLReader and XML Parser extensions (http://php.net/manual/en/book.xmlreader.php and http://php.net/manual/en/book.xml.php, respectively). XMLReader works by using a cursor-based parsing approach, while XML Parser uses a push-based approach. Here are some drawbacks though when using these extensions: - validation may not be possible (true XML Parser) - you can't use XPath to browse through the data (true for both extensions) Hope this helps.

It appears that the HTML DOM features in php are not able to handle large html files (200k+). It's slow down when processing these files. I would like to request that the DOM processing objects be given a speed boost. The DOM that's present in the browsers are much faster at processing the element. If this can be done then it would be great! ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=44761&edit=1
