嗨伙计们，我如何从下面的xml中提取金额？

The formatted XML would look like:
格式化的XML看起来像：
<balance>
<amount value="1000" currencyCode="GBP" exponent="2" debitCreditIndicator="credit" />
</balance>
As you can see, value is not a separate node, so you'll have to access it as below (assuming you're using SimpleXML to do the parsing):
如您所见，value不是一个单独的节点，因此您必须按如下方式访问它（假设您使用SimpleXML进行解析）：
$xml = simplexml_load_string($str); // $str contains your XML string
$lastEvent = $xml->amount['value'];
演示！
