在 XML 文档中搜索字符串

Question

我正在尝试通过 Unity3D 中的 XML 文档（使用 uJS 和 MSDN XmlDocument class）搜索包含指定字符串的节点（在这个测试中我正在寻找 'Logs'）然后捕获匹配节点父节点的名称属性的值。

但是我在这个过程中的某个地方搞砸了；它目前正在传递 all 节点的 if 语句（而不仅仅是匹配的节点），因此返回 XML 文档中的所有父名称。任何人都可以帮助我理解我的逻辑以使其正常工作吗？

非常感谢，

当前代码：

var mpo = xmlRoot.SelectNodes("MetaPipeObject");
         
     for (var i = 0; i < mpo.Count; i++)
     {
         var curNode = mpo[i];
         var nodeCheck = curNode.SelectNodes("//*[contains(text(), 'Logs')]");
         
         Debug.Log("nodeCheck: " + nodeCheck.Count);
         
         if (nodeCheck.Count > 1)
         {
             Debug.Log(curNode.SelectSingleNode("@name").Value);
         }
     }
 }

XPath-expression // 从根元素开始搜索。在您的情况下，足以进行 .// - 从当前元素搜索。

var nodeCheck = curNode.SelectNodes(".//*[contains(text(), 'Logs')]");
