Question

我需要使用TFS的全局列表。我已经下载了它，并可以访问具有名称空间的xml。我创建了XmlNamespaceManager，但是在获取所需节点时仍然遇到问题。对于那些不熟悉的人，TFS全球列表看起来像这样：

<gl:GLOBALLISTS xmlns:gl="http://schemas.microsoft.com/VisualStudio/2005/workitemtracking/globallists">
    <GLOBALLIST name="Builds">
        <LISTITEM value="..." />
    </GLOBALLIST>
...
    <GLOBALLIST name="Client Name">
        <LISTITEM value="Test" />

将全局列表下载到XmlDocument之后，我使用以下代码尝试提取测试节点，但返回的是空值。

Dim globalList As XmlDocument = store.ExportGlobalLists()
Dim nsManager As XmlNamespaceManager = New XmlNamespaceManager(globalList.NameTable)
nsManager.AddNamespace("gl", "http://schemas.microsoft.com/VisualStudio/2005/workitemtracking/globallists")
Dim node As XmlNode = globalList.SelectSingleNode("//gl:GLOBALLISTS/gl:GLOBALLIST[@name='Client Name']/gl:LISTITEM[@value='" + Name + "']", nsManager)

作为旁注，我正在搜索的名称确实存在。我还在即时窗口中尝试了以下方法：

globalList.SelectNodes("/gl:GLOBALLISTS", nsManager)
Expression has been evaluated and has no value
globalList.SelectSingleNode("//gl:GLOBALLISTS/gl:GLOBALLIST[name='Client Name']/gl:LISTITEM[value='" + Name + "']", nsManager)
Expression has been evaluated and has no value
globalList.SelectSingleNode("//gl:GLOBALLIST[name='Client Name']/gl:LISTITEM[value='" + Name + "']", nsManager)
Expression has been evaluated and has no value
globalList.SelectSingleNode("//gl:GLOBALLIST[name='Client Name']", nsManager)
Expression has been evaluated and has no value
globalList.SelectSingleNode("//gl:GLOBALLIST", nsManager)
Expression has been evaluated and has no value
globalList.SelectSingleNode("//gl:GLOBALLISTS/GLOBALLIST[name='Client Name']/LISTITEM[value='Test']", nsManager)
Expression has been evaluated and has no value
globalList.SelectSingleNode("/gl:GLOBALLISTS/gl:GLOBALLIST[@name='Client Name']/gl:LISTITEM[@value='" + Name + "']", nsManager)
Expression has been evaluated and has no value

解决方案

除了第一个节点外，我必须取出名称空间引用，并按照下面的答案中的建议添加@符号以访问属性。

Dim node As XmlNode = globalList.SelectSingleNode("//gl:GLOBALLISTS/GLOBALLIST[@name='Client Name']/LISTITEM[@value='" + Name + "']", nsManager)

在XPath中，使用html .inputHighlightText:focus { overflow: hidden!important; -webkit-overflow: hidden!important; -moz-overflow: hidden!important; -o-overflow: hidden!important; -ms-overflow: hidden!important; } this.preventDefault = function(e) { e = e || window.event; if (e.preventDefault) e.preventDefault(); e.returnValue = false; } this.disable_scroll_mobile = function(el = null){ if(el !== null) { $(el).focus((e) => { e.preventDefault(); }); } $("body").css("overflow", "hidden!important"); $("#fullScreenBg").css("overflow", "hidden!important"); $(window).css("overflow", "hidden!important"); window.addEventListener('touchmove',$self.preventDefault, false); document.addEventListener('touchmove',$self.preventDefault, false); window.addEventListener('scroll',$self.preventDefault, false); document.addEventListener('scroll',$self.preventDefault, false); } this.enable_scroll_mobile = function(){ $("body").css("overflow", "scroll"); $("#fullScreenBg").css("overflow", "scroll"); $(window).css("overflow", "scroll"); window.removeEventListener('touchmove',$self.preventDefault, false); document.removeEventListener('touchmove',$self.preventDefault, false); window.removeEventListener('scroll',$self.preventDefault, false); document.removeEventListener('scroll',$self.preventDefault, false); } this.disable_scroll_mobile();指示属性。这似乎是您遇到问题的原因，因为您没有使用@。

此外，正如您自己发现的那样，只有最外面的元素位于名称空间中，因此只有第一段应具有@。

XML上的GetSingleNode，名称空间不起作用
