用属性xml php写元素

Question

我正在使用php编写xml。我想用元素写属性。我的代码如下

$writer = new XMLWriter();  
$writer->openURI('php://output');   
$writer->startDocument('1.0','UTF-8');   
$writer->setIndent(4);   
$writer->startElement('Response');
$writer->writeElement("Dial","+111111111");
$writer->endElement();
$writer->endDocument();   
$writer->flush();

这会产生此输出

<response>
<dial>+111111</dial>
</response>

但我想要这样的东西

<response>
<dial action="myaction">+111111</dial>
</response>

我试过这个

$writer->writeAttribute('action', 'myaction');

但是这只添加了startElement而不是writeElement。 感谢

Answer 1

而不是行$writer->writeElement("Dial","+111111111");您应该在某些步骤中编写元素以添加属性

$writer->startElement("Dial");
$writer->writeAttribute('action', "myaction");
$writer->text("+111111111");
$writer->endElement();
