范例

示例 #1 Intermixing Sub-elements and Attributes

If writing sub-elements and attributes is intermixed, any attempt to write attributes after the first sub-element will fail and return false.

<?php
$xml 
= new XMLWriter();
$xml->openMemory();

$xml->startElement('element');
$xml->writeAttribute('attr1''0');
$xml->writeElement('subelem''0');
var_dump($xml->writeAttribute('attr2''0'));
$xml->endElement();

echo 
$xml->flush();
?>

以上例程会输出:

bool(false)
<element attr1="0"><subelem>0</subelem></element>
