  • 生成XML文件,并保存到本地文件 Alec

    生成如下结构的XML文件:

    <anychart> 
    <charts> 
        <chart plot_type="CategorizedVertical"> 
          <data> 
            <series name="Year 2003" type="Bar"> 
              <point name="AAA" y="7649" /> 
              <point name="BBB" y="4567" /> 
              <point name="CCC" y="6410" /> 
            </series> 
          </data> 
          <chart_settings> 
            <title> 
              <text>销售<text> 
            </title> 
            <axes> 
              <y_axis> 
                <title>Sales</title> 
              </y_axis> 
              <x_axis> 
                <title>Retail Channel</title> 
              </x_axis> 
            </axes> 
          </chart_settings> 
        </chart> 
    </charts> 
    </anychart> 

    代码如下:

    protected void Page_Load(object sender, EventArgs e)
            {
                DataBind databind = new DataBind();
                DataSet ds = databind.ABCData();
                string plot_type = "CategorizedVertical";
                XmlDocument doc = new XmlDocument();
                XmlElement Node = doc.CreateElement("anychart");//创建一个anychart节点          
                doc.AppendChild(Node);
                XmlElement Node1 = doc.CreateElement("charts");//创建节点anychart子节点charts   
                doc.DocumentElement.AppendChild(Node1);
                XmlElement Node2 = doc.CreateElement("chart");//创建节点charts子节点chart    
                Node2.SetAttribute("plot_type", plot_type);//为节点chart添加plot_type属性     
                Node1.AppendChild(Node2);
                XmlElement Node3 = doc.CreateElement("data");//创建节点chart第一个子节点data   
                Node2.AppendChild(Node3);
                XmlElement Node4 = doc.CreateElement("chart_settings");//创建节点chart第二个子节点chart_settings    
                Node2.AppendChild(Node4);
                XmlElement Node5 = doc.CreateElement("series");//创建节点data子节点series
                Node5.SetAttribute("name", "Year 2003");//为series节点添加第一个属性name     
                Node5.SetAttribute("type", "Bar");//为series节点添加第二个属性type    
                Node3.AppendChild(Node5);
                for (int i = 1; i <= 3; i++)
                {
                    XmlElement Node13 = doc.CreateElement("point");//在节点series中创建子节点point    
                    Node13.SetAttribute("name", ds.Tables[0].Rows[i - 1]["products_Name"].ToString());//为point节点添加属性name并将ds.Tables[0]中products_Name一列数据逐行取出,赋值给属性name 
                    Node13.SetAttribute("y", ds.Tables[0].Rows[i - 1]["products_Quantity"].ToString());//为point节点添加属性y并将ds.Tables[0]中products_Quantity一列数据逐行取出,赋值给属性y           
                    Node5.AppendChild(Node13);
                }
                XmlElement Node6 = doc.CreateElement("title");
                Node4.AppendChild(Node6);
                XmlElement Node7 = doc.CreateElement("axes");
                Node4.AppendChild(Node7);
                XmlElement Node8 = doc.CreateElement("y_axis");
                Node7.AppendChild(Node8);
                XmlElement Node9 = doc.CreateElement("x_axis");
                Node7.AppendChild(Node9);
                XmlElement Node10 = doc.CreateElement("title");
                Node10.InnerText = "Sales";//为节点title赋值Sales   
                Node8.AppendChild(Node10);
                XmlElement Node11 = doc.CreateElement("title");
                Node11.InnerText = "Retail Channel";
                Node9.AppendChild(Node11);
                XmlElement Node12 = doc.CreateElement("text");
                Node12.InnerText = "销售";
                Node6.AppendChild(Node12);
                doc.Save("D:\test.xml"); //保存xml       
            }

    如果想判断一下文件D:\test.xml是否存在,可以通过如下的代码进行:

    string path = "D:\test.xml";
                    if (Directory.Exists(path) == false)
                    {
                        Directory.CreateDirectory(path);
                    }

    最后把path传给doc.save(path)就OK了……
