SimpleXMLElement->asXML()

Return a well-formed XML string based on SimpleXML element ()

SimpleXMLElement {
  mixed asXML(string filename);
}

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

Parameters

filename

If specified, the function writes the data to the file rather than returning it.

Return Values

If the filename isn't specified, this function returns a string on success and FALSE on error. If the parameter is specified, it returns TRUE if the file was written successfully and FALSE otherwise.

Examples

Example 2249. Get XML

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

$xml = new SimpleXMLElement($string);

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

?>


asXML also works on Xpath results:

Example 2250.  Using asXML() on Xpath results

<?php
// Continued from example XML above.

/* Search for <a><b><c> */
$result = $xml->xpath('/a/b/c');

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