(PHP 5)
simplexml_load_string — Interprets a string of XML into an object
Takes a well-formed XML string and returns it as an object.
A well-formed XML string
You may use this optional parameter so that simplexml_load_string() will return an object of the specified class. That class should extend the SimpleXMLElement class.
Since PHP 5.1.0 and Libxml 2.6.0, you may also use the options parameter to specify additional Libxml parameters.
Returns an object of class SimpleXMLElement with properties containing the data held within the xml document. On errors, it will return FALSE.
Example #1 Interpret an XML string
<?php
$string = <<<XML
<?xml version='1.0'?>
<document>
<title>Forty What?</title>
<from>Joe</from>
<to>Jane</to>
<body>
I know that's the answer -- but what's the question?
</body>
</document>
XML;
$xml = simplexml_load_string($string);
var_dump($xml);
?>
上例将输出：
SimpleXMLElement Object ( [title] => Forty What? [from] => Joe [to] => Jane [body] => I know that's the answer -- but what's the question? )
At this point, you can go about using $xml->body and such.
