(PHP 5 >= 5.0.1, PHP 7)
SimpleXMLElement::asXML — Return a well-formed XML string based on SimpleXML element
The asXML method formats the parent object's data in XML version 1.0.
filename
If specified, the function writes the data to the file rather than returning it.
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.
Example #1 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();
?>
以上例程会输出:
<?xml version="1.0"?> <a> <b> <c>text</c> <c>stuff</c> </b> <d> <c>code</c> </d> </a>
asXML also works on Xpath results:
Example #2 Using asXML() on SimpleXMLElement::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();
}
?>
以上例程会输出:
<c>text</c><c>stuff</c>
