Answer 1

In theory you can provide the LIBXML_NOXMLDECL option to drop the XML declaration when saving a document, but this is only available in Libxml >= 2.6.21 (and buggy). An alternative would be to use

$customXML = new SimpleXMLElement('<abc></abc>');
$dom = dom_import_simplexml($customXML);
echo $dom->ownerDocument->saveXML($dom->ownerDocument->documentElement);

Answer 2

A practical solution: you know that the first occurrence of ?> in the result string is going to be then end of the xml version substring. So:

$customXML = new SimpleXMLElement('<abc></abc>');
$customXML = substr($customXML, strpos($customXML, '?'.'>') + 2);

Note that ?> is split into two parts because otherwise some poor syntax highlighter may have problems parsing at this point.

Answer 3

echo preg_replace("/<\\?xml.*\\?>/",'',$doc->saveXML(),1);

Answer 4

$customXML = new SimpleXMLElement('<source><abc>hello</abc></source>');
$result = $customXML->xpath('//abc');
$result = $result[0];
var_dump($result->asXML());

Answer 5

If this is a problem, this should do it:

$xml = str_replace(' version="1.0"', '', $xml);`

Answer 6

As SimpleXMLElement always uses "\n" to separate the XML-Declaration from the rest of the document, it can be split at that position and the remainder taken:

explode("\n", $customXML->asXML(), 2)[1];

Example:

<?php

$customXML = new SimpleXMLElement('<!-- some comment -->
<abc>
</abc>');

echo explode("\n", $customXML->asXML(), 2)[1];

Output:

<!-- some comment -->
<abc>
</abc>
