Php 解析命名xml

php xml

Php 解析命名xml,php,xml,simplexml,Php,Xml,Simplexml,可能重复： 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->creationdatet

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，但这不会为我返回任何内容。我熟悉解析简单的xml，但名称空间的xml给我带来了困难，特别是因为所有示例都嵌入了名称空间的xml，而不是整个内容都是名称空间的

我试过这个密码

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

    print print_r($simpleXml, TRUE);
但这并没有为creationdatetime打印出任何内容。当我打印$simpleXml时，它会打印这个

SimpleXMLElement Object ( [@attributes] => Array ( [revision] => 1.0 [environment] => Production [lang] => en-US )
下面是打印出来的$simpleXml的值
