DOMDocument::loadXML — Load XML from a string
Loads an XML document from a string.
This method may also be called statically to load and create a DOMDocument object. The static invocation may be used when no DOMDocument properties need to be set prior to loading.
如果成功则返回 TRUE，失败则返回 FALSE。 If called statically, returns a DOMDocument and issues E_STRICT warning.
If an empty string is passed as the source , a warning will be generated. This warning is not generated by libxml and cannot be handled using libxml's error handling functions.
Example #1 Creating a Document
<?php
$doc = new DOMDocument();
$doc->loadXML('<root><node/></root>');
echo $doc->saveXML();
?>
Example #2 Static invocation of loadXML
<?php
$doc = DOMDocument::loadXML('<root><node/></root>');
echo $doc->saveXML();
?>
