说明

mixed SimpleXMLElement->asXML ( [string filename] )

The asXML method formats the parent object's data in XML version 1.0.

例子 1. Get XML

<?php
$string = <<<XML
<a>
<b>
  <c>text</c>
  <c>stuff</c>
</b>
<d>
  <c>code</c>
</d>
</a>
XML;

$xml = simplexml_load_string($string);

echo $xml->asXML(); // <?xml ... <a><b><c>text</c><c>stuff</c> ...

while(list( , $node) = each($result)) {
    echo $node->asXML(); // <c>text</c> and <c>stuff</c>
}
