Question

我有以下XML文件我想找回一些价值。我尝试使用x-path的问题，但它没有用。

这是xml文件：

我想从＆＃39; Flight Segment＆＃39;中检索价值。元件

Answer 1

Xpath应该可以工作：

    $soap = new DOMDocument();
    $soap -> preserveWhiteSpace = FALSE;        
    $soap ->load([source url);

    $query = "//FlightSegment";
    $xPathObject = new DOMXPath($soap);
    $searchQuery = $xPathObject->query($query);

$query = "//FlightSegment"：//从文档中的任何位置选择节点。 FlightSegment是node，应使用xpath从文档中检索。

变量FlightSegment中将存储三个$searchQuery个节点。您可以使用$searchQuery->item(#)访问它们，其中#是项目索引。在这种情况下为0,1或2。

PHP访问复杂的xml元素
