c# 读取opencv 生成的svm训练好的xml分类器

需要用到opencv里面SVM训练分类器的数据：

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.IO;using System.Xml;using System.Xml.Linq; //需要添加的namespace xml_duqu{    public partial class Form1 : Form    {        static string strPath ;          public Form1()        {            InitializeComponent();        }        private void button1_Click(object sender, EventArgs e)        {            OpenFileDialog open = new OpenFileDialog();            if (open.ShowDialog() == DialogResult.OK)            {                strPath = open.FileName;                                test(strPath);            }        }        private void test(string filename)        {            XElement xe = XElement.Load(strPath);//加载XML文件              //使用LINT从XML文件中查询信息              XmlTextReader reader = new XmlTextReader(filename);            XmlDocument xml = new XmlDocument();            //读取xml文件            xml.Load(filename);  //你的xml地址                        richTextBox1.Text = "";            FileStream fs = new FileStream("data.data", FileMode.Create);            StreamWriter sw;             sw = new StreamWriter(fs, Encoding.Default);            bool flag = false;            while (reader.Read())            {                if (reader.Name != "")                {                    if (reader.Name == "sv_total" || reader.Name == "_" || reader.Name == "rho" || reader.Name == "alpha" || reader.Name == "index")//根据想要的属性保存数据                    {                        //if (reader.Name == "sv_total" || reader.Name == "rho" || reader.Name == "alpha" || reader.Name == "index")                        //sw.WriteLine(reader.Name);                        flag = true;                    }                }                if (reader.Name == ""&& flag)                {                   // richTextBox1.Text = richTextBox1.Text + reader.Name + "\n";                   // sw.WriteLine(reader.Name);                    if (reader.HasValue)                    {                        richTextBox1.Text = richTextBox1.Text + reader.Value + "\n";                         string uu= reader.Value.Replace("\r\n","");                         string []m = uu.Split(' ');                       for (int i = 0; i < m.Length; i++)                       {                           if (m[i] != "\r\n" && m[i] != "")                               sw.Write(m[i]+" ");    //保存到TXT 文件里面                       }                            sw.WriteLine();                        flag = false;                    }                }                            }            sw.Close();            sw.Dispose();                    }        }        } 

效果如下：

winform 效果

TXT 效果

XML 文件

下面是把不同的属性存在不同的文件里面
