使用 SimpleXML 使用命名空间解析 XML

我很难解析 simpleXml 字符串以获取值。我试过了

$xml = new SimpleXmlElement($simpleXml);

$xml->registerXPathNamespace("ns0", "http://www.openapplications.org/oagis");
foreach($xml->xpath('//ns0:applicationarea/a:sender') as $n) {
  echo $n->creationdatetime . "success";
}

获取 creationdatetime 字段，但这并没有为我返回任何内容。我熟悉解析简单的 xml，但命名空间 xml 给我带来了困难，特别是因为所有示例总是嵌入命名空间 xml，而不是整个东西都被命名空间。

我试过这段代码。

$simpleXml = simplexml_load_string($xml);
    print $simpleXml->children('ns0', true)->applicationarea->creationdatetime;

    print print_r($simpleXml, TRUE);

但这并没有为创建日期时间打印出任何内容。当我打印出 $simpleXml 时，它会打印出这个

SimpleXMLElement Object ( [@attributes] => Array ( [revision] => 1.0 [environment] => Production [lang] => en-US )

下面是 $simpleXml 的值，打印出来

<ns0:syncparty xmlns:ns0="http://www.openapplications.org/oagis" revision="1.0" environment="Production" lang="en-US">

没有必要仅仅因为你有命名空间就使用 XPath。请阅读->children()和->attributes()方法。

在你的情况下：

$xml->children('ns0', true)->applicationarea->creationdatetime

或者，如果您不想依赖“ns0”前缀，请使用完整的命名空间标识符：

$xml->children('http://www.openapplications.org/oagis')->applicationarea->creationdatetime

另外，请注意，在您显示的代码段中，creationdatetime节点不在sender节点中，并且没有a:名称空间前缀，您当前的代码都假定这两者。
