ASP.NET生成层次较复杂的XML
1.业务逻辑层:
public DataSet ABCData()
{
DataBase db = new DataBase();
string sql = "select * from products where products_Year='2008'";
DataSet ds = db.GetDataSet(sql);
return ds;
}
注sql执行结果:
produts_Id products_Name products_Quantity products_Year
38 AAA 7649 2008
39 BBB 4567 2008
40 CCC 6410 2008
2.数据访问层略:
3.表示层:
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(Server.MapPath("test.xml")); //保存xml
}
4.生产的xml:
<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>
