    示例

    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();
    ?>

    以上示例会输出：

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