xml操作SelectNodes报错:表达式的计算结果必须为节点集

[hh0702]

在执行 ReadResource("ConfigItemEdit", "yy-en.xml") 报错:
表达式的计算结果必须为节点集。

请帮看看错在哪里，谢谢!!!




public static Hashtable ReadResource(string frmName, string lang)
{
Hashtable result = new Hashtable();
XmlReader reader = null;
reader = new XmlTextReader(lang );

XmlDocument doc = new XmlDocument();
doc.Load(reader);

XmlNode root = doc.DocumentElement;
XmlNodeList nodelist = root.SelectNodes( "[Name=" + frmName + "]/Controls/Control");
//最后一句报错:表达式的计算结果必须为节点集。

foreach (XmlNode node in nodelist)
{
try
{
XmlNode node1 = node.SelectSingleNode("@name");
XmlNode node2 = node.SelectSingleNode("@text");
if (node1 != null)
{
result.Add(node1.InnerText.ToLower(), node2.InnerText);
}
}
catch (FormatException fe)
{
Console.WriteLine(fe.ToString());
}
}
reader.Close();
return result;
}






文件:yy-en.xml



<?xml version="1.0" encoding="utf-8" ?>
<Resource>
<Form>
<Name>ConfigItemEdit</Name>
<Controls>
<Control name="txtTtitle" text="Ttitle~" />
<Control name="txtTips" text="tipsssssssssssss:" />
<Control name="chkEnabledStatet" text="kq" />
</Controls>
</Form>

<Form>
<Name>FrmPasswordChange</Name>
<Controls>
<Control name="txtTtitle" text="Ttiasdfasdfa234234234234sdfasdftle~" />
<Control name="txtTips" text="tipsssssssssasdfasd34234234ssss:" />
<Control name="chkEnabledStatet" text="k23423423423423q" />

</Resource>

自己顶一下，在线等待~

[Icedmilk]

"/Resource/Form[Name = \"ConfigItemEdit\"]/Controls/Control"

XPath 这样写试试

[se7en]

肯定是xml文件对应的节点啊 。应该不能是整个xml文件吧

[hh0702]

还是没解决

Icedmilk 能详细说说么

    public static Hashtable ReadResource(string fldname,string path)
    {
        Hashtable hs = new Hashtable();
        XmlDocument xml = new XmlDocument();
        xml.Load(path);
        XmlNodeList node = xml.SelectSingleNode("//Name[text()='" + fldname + "']").NextSibling.SelectNodes("Control");
        foreach (XmlNode n in node)
        {
            hs.Add(n.Attributes["name"].Value, n.Attributes["text"].Value);
        }
        return hs;
    }
//调用
        string path = Server.MapPath("XMLFile3.xml");
        Hashtable hs = ReadResource("FrmPasswordChange", path);
        foreach (DictionaryEntry d in hs)
        {
            Response.Write(d.Key + "===" + d.Value + "<br/>");

感谢 huangwenquan123 !

用你的方法搞定，用xml做多语言还是蛮方便~
