php simplexml without xml declaration tag [duplicate]

Question

I use SimpleXML to generate XML. When I use :

new SimpleXMLElement('<row></row>');

SimpleXML generates this XML :

<?xml version="1.0"?>\n<row/>

But I need only :

<row/>

I need only it because I will include it to another XML.

How can I generate only row tag in an SimpleXML Object ?

As has been outlined in the earlier Q&A:

• remove xml version tag when a xml is created in php

You can import the SimpleXMLElement into the PHP Document Object Model (DOM) extension and output it there as XML because that extension can output without the XML declaration.

Importing into dom works with the dom_import_simplexml function.

Example:

$xml    = new SimpleXMLElement('<row></row>');
$domxml = dom_import_simplexml($xml);
echo $domxml->ownerDocument->saveXML($domxml->ownerDocument->documentElement);

Output:

<row/>

Hope this helps you.
