我试图通过谷歌使用我发现的几种方法从PHP获取旅程数据，但我无法让它工作，很可能是由于命名空间。我必须承认我不是XML专家。在搜索这个网站时，我发现了一个与this HOWTO链接的类似帖子。

我打算为我的XML创建等效代码，但我没有获得旅程信息：

// $result_xml is the XML posted above
$xml_obj = simplexml_load_string($result_xml, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/");

  if ($xml_obj === false) {
    show_error("Failed loading XML");
    foreach(libxml_get_errors() as $error) {
        echo "ERROR: \t", $error->message;
    }
  }
  else {
    show_info("XML loaded. Children: ");
    foreach($xml_obj->children() as $child) {
      print("Child: " . var_dump($child) . "");
    }
    show_info("Attributes: ");
    foreach($xml_obj->attributes() as $attribute) {
      print("Attributes: " . var_dump($attribute) . "");
    }
    show_info("Journeys: ");
    foreach($xml_obj->journeys as $journey) {
      $ns_dc = $journey->children('http://output.journeysearch.v_1_2.services.inforcyl.com/xsd');
      print("Journey cashCardAllowed: " . $ns_dc->cashCardAllowed  . "");
    }

    //echo "As XML: " . $xml_obj->asXML();  // This returns the XML just fine
  }

这给了我以下输出：

XML loaded. Children:
Attributes:
Journeys:

有人可以帮我使用XML命名空间来获取旅程数据吗？我是否还需要为每个子元素指定命名空间？

我需要：

<ax21132:fareIfOutward>27.0</ax21132:fareIfOutward>
<ax21132:fareIfReturn>54.0</ax21132:fareIfReturn>
<ax21134:departureDate>01/01/2014</ax21134:departureDate>
<ax21134:departureTime>12:30</ax21134:departureTime>
