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……
