范例
Example #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>
