Question

我有XML喜欢

<rss>
<channel>
    <item>
        <category domain="category" nicename="change"><![CDATA[Changing Lives]]></category>
        <category domain="category" nicename="events"><![CDATA[Events]]></category>
        <category domain="category" nicename="leadership"><![CDATA[Leadership]]></category>
        <category domain="category" nicename="spiritual-transformation"><![CDATA[Spiritual Transformation]]></category>
    </item>
    <item></item>
    <item></item>
</channel>
</rss>

我正在尝试阅读类别innertext（改变生活，事件，领导力）...使用foreach条件..但是对于每个循环我只能改变生活..这里是我的代码

    protected void btnImportPost_Click(object sender, EventArgs e)
{

    XmlDocument doc = new XmlDocument();
    string strPath = Server.MapPath("~/App_Data/willowcreekassociationblog.wordpress.xml");
    doc.Load(strPath);
    //Get Channel Node
    XmlNode channelNode = doc.SelectSingleNode("rss/channel");
    if (channelNode != null)
    {
        DateTime temp;
        //Add NameSpace
        XmlNamespaceManager nameSpace = new XmlNamespaceManager(doc.NameTable);
        nameSpace.AddNamespace("excerpt", "http://wordpress.org/export/1.2/excerpt/");
        nameSpace.AddNamespace("content", "http://purl.org/rss/1.0/modules/content/");
        nameSpace.AddNamespace("dc", "http://purl.org/dc/elements/1.1/");
        nameSpace.AddNamespace("wfw", "http://wellformedweb.org/CommentAPI/");
        nameSpace.AddNamespace("wp", "http://wordpress.org/export/1.2/");

        //Parse each item
        foreach (XmlNode itemNode in channelNode.SelectNodes("item"))
        {
            //some code here

            foreach (XmlNode categoryNode in itemNode.SelectNodes("category"))
            {
                //CMS.SiteProvider.CategoryInfo GetCate = null;
                string CategoryName = itemNode.SelectSingleNode("category").InnerText;
                Response.Write(@"<script language='javascript'>alert('root Document:" + CategoryName + "');</script>");

            }

        }
    }
}

Answer 1

只需使用

string CategoryName = categoryNode.InnerText;

Answer 2

原因是你不是每次循环都写出itemNode的InnerText，而是使用SelectSingleNode来拔出第一个匹配。

尝试将内循环更改为：

foreach (XmlNode categoryNode in itemNode.SelectNodes("category"))
{
   //CMS.SiteProvider.CategoryInfo GetCate = null;

   //string CategoryName = itemNode.SelectSingleNode("category").InnerText; // incorrect
   string CategoryName = categoryNode.InnerText;
   Console.Write(CategoryName);
}

使用xmlnode读取重复xml
