我有以下两行代码：
Dim node As XmlNode = xDoc.SelectSingleNode("//response/agentStatusList/agentStatus/protectableVolumes/protectableVolume/metrics/lastWriteTime")
MsgBox(node.FirstChild.Value)
我希望获得lastWriteTime的第一个实例的值，它应该是2011-10-13T10:48:48.3833771-04:00，但代码只会弹出一个空字符串。很抱歉这篇文章很重要，但这里是整个XML文件供参考。任何人都可以看到为什么这不起作用，或者给我一个如何让它以其他方式工作的例子？

答案 0 :(得分：3)
您的节点都在非空命名空间中，并且您没有在XPath查询中指定此命名空间。这就是为什么它一无所获。
示例：
Dim resolver = New XmlNamespaceManager(xDoc.NameTable)
resolver.AddNamespace("c", "replayc.Xml.Contracts")
Dim node = xDoc.SelectSingleNode("//c:response/c:agentStatusList/c:agentStatus/c:protectableVolumes/c:protectableVolume/c:metrics/c:lastWriteTime", resolver)
您在XPath文本中使用的名称空间前缀完全是任意的，只要它映射到的URI与文档中的名称空间URI匹配。
答案 1 :(得分：0)
您的XML文档具有默认命名空间（xmlns="replayc.Xml.Contracts"）。
您必须在发出XPath查询之前注册该命名空间，当然您必须在查询本身中使用该命名空间。
Dim nsMgr As New XmlNamespaceManager(xDoc)
nsMgr.AddNamespace("c", "replayc.Xml.Contracts")
Dim xpath As String = "//c:response/c:agentStatusList/c:agentStatus/c:protectableVolumes/c:protectableVolume/c:metrics/c:lastWriteTime"
Dim node As XmlNode = xDoc.SelectSingleNode(xpath, nsMgr)
MsgBox(node.FirstChild.Value)
