我需要获取节点 SiteID 的值，其中节点 Site 与我传递的任何变量匹配。我的代码是：

$xml_file ='SiteDetails.xml';
$xmlDoc = new DomDocument();
$xmlDoc->load($xml_file);
$xpath = new DOMXpath($xmlDoc);

$siteIDList =  $xpath->query("/GeteBayDetailsResponse/SiteDetails[Site=$site]/SiteID");

var_dump($siteIDList);
echo $siteIDList->SiteID;

我得到以下结果：

object(DOMNodeList)#11 (0) {
}

任何人都可以帮忙吗？我想获得 3 的值。

编辑：使用 Florent 回答中的 API registerNamespace。

您的 XML 文件包含默认命名空间。ebay因此，您可以在代码中针对默认命名空间 ( )注册一个变量名称，urn:ebay:apis:eBLBaseComponents如下所示，并使用以下 xpath

$xpath->registerNamespace('ebay', 'urn:ebay:apis:eBLBaseComponents');

$siteIDList = $xpath->query("//ebay:Site[text()='$site']/following-sibling::ebay:SiteID/text()");

或者

您可以使用以下 XPATH，除了评估它之外不需要任何额外的代码:-)

//*[namespace-uri()='urn:ebay:apis:eBLBaseComponents' and name()='Site' and text()='$site']/following-sibling::*[namespace-uri()='urn:ebay:apis:eBLBaseComponents' and name()='SiteID']/text()

注意： $site 是要匹配的<Site>节点的运行时值。<SiteID>

我认为你必须$site用引号括起来并添加命名空间：

$xpath = new DOMXPath($xmlDoc);
$xpath->registerNamespace('ebay', 'urn:ebay:apis:eBLBaseComponents');

$siteIDList = $xpath->query("/ebay:GeteBayDetailsResponse/ebay:SiteDetails[ebay:Site='$site']/ebay:SiteID");

只是为了确定，能给我们$site提供这个结果的值吗？

编辑：按照 Vaman Kulkarni 的建议添加了命名空间。
