我将节点插入xml文件时出现问题 [英] problem when I insert node to my xml file

问题描述

大家好:)

我有这个xml文件:

hi all :)

I have this xml file:

<categories>
  <itemdetails>
    <item>
      <text>first</text>
      <categoryid>1</categoryid>
    </item>
    <item>
      <text>Other</text>
      <categoryid>2</categoryid>
    </item>
  </itemdetails>
  <setting>
    <verticaldistance>50</verticaldistance>
    <itemcolour>666666</itemcolour>
    <itemrollovercolour>000000</itemrollovercolour>
  </setting>
</categories>

我用这种方式插入一个新节点，我知道这是一个旧节点:

and I use this way to insert a new node, I know it''s an old one:

DataSet objDataSet = new DataSet();
       
        objDataSet.ReadXml(Server.MapPath("~/" + RadComboBox1.SelectedValue + "/c.xml"));
        
        DataTable objTable = null;
        DataRow objNewRow = null;
        objTable = objDataSet.Tables["item"];
        
        objNewRow = objTable.NewRow();
        objNewRow["text"] = RadTextBox1.Text;
        Random _random = new Random();
        int _intrandom = _random.Next(0, 999999999);
        objNewRow["categoryID"] = _intrandom;
        objTable.Rows.Add(objNewRow);
        objDataSet.WriteXml(Server.MapPath("~/" + RadComboBox1.SelectedValue + "/c.xml"));
        RadTextBox1.Text = "";

但从< itemdetails>插入的节点节点

像这样:

but the node inserted out of <itemdetails> node

like this:

<categories>
  <itemdetails>
    <item>
      <text>first</text>
      <categoryid>1</categoryid>
    </item>
    <item>
      <text>Other</text>
      <categoryid>2</categoryid>
    </item>
  </itemdetails>
  <item>
    <text>NewNode</text>
    <categoryid>whatever</categoryid>
  </item>
  <setting>
    <verticaldistance>50</verticaldistance>
    <itemcolour>666666</itemcolour>
    <itemrollovercolour>000000</itemrollovercolour>
  </setting>
</categories>

如何将其插入正确的位置，任何人都可以帮助我?

how can I insert it to the right place, any one help me ?

推荐答案

尝试一下

objTable = objDataSet.Tables["itemdetails"];
