(no version information, might be only in CVS)

SimpleXMLElement->asXML --  Return a well-formed XML string based on SimpleXML element

Description

mixed SimpleXMLElement->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 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> ...

?>

asXML also works on Xpath results:

Example 2. 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>
}
?>
