小编Fun*_*onR的帖子

我有一个XML文件

<ns0:Employees xmlns:ns0="http://TestIndexMap.Employees">
  <Employee FirstName="FirstName_0" LastName="LastName_1" dept="dept_2" empNumber="1">
    <Schedules>
      <Schedule Date_join="2008-01-20" Date_end="2008-01-30" />
    </Schedules>
  </Employee>
  <Employee FirstName="FirstName_0" LastName="LastName_1" dept="dept_2" empNumber="2">
    <Schedules>
      <Schedule Date_join="2008-01-20" Date_end="2008-01-30" />
    </Schedules>
  </Employee>
  <Employee FirstName="FirstName_2" LastName="LastName_1" dept="dept_2" empNumber="2">
    <Schedules>
      <Schedule Date_join="2007-01-21" Date_end="2007-12-30" />

    </Schedules>
  </Employee>
  <Employee FirstName="FirstName_2" LastName="LastName_1" dept="dept_2" empNumber="2">
    <Schedules>
      <Schedule Date_join="2007-01-21" Date_end="2007-12-30" />
      <Schedule Date_join="2008-06-20" Date_end="2008-01-30" />

    </Schedules>
  </Employee>
</ns0:Employees>

我想根据fistname,姓氏和date_join以及data_end删除重复项.

请问,有人可以解释如何使用XSLT实现这一目标吗？

我有一个如下所示的数据集:

id,created_at,username
1,2006-10-09T18:21:51Z,hey
2,2007-10-09T18:30:28Z,bob
3,2008-10-09T18:40:33Z,bob
4,2009-10-09T18:47:42Z,john
5,2010-10-09T18:51:04Z,brad
...

我包含1M +行.我想使用python从中提取用户名列表而不重复.到目前为止我的代码看起来像这样:

import csv

file1 = file("sample.csv", 'r')
file2 = file("users.csv", 'w')

reader = csv.reader(file1)
writer = csv.writer(file2)

rownum = 0
L = []
for row in reader:
    if not rownum == 0:
        if not row[2] in L:
            L.append(row[2])
            writer.writerow(row[2])

    rownum += 1

我有几个问题:1 - 我在users.csv中的输出如下所示:

h,e,y
b,o,b
j,o,h,n
b,r,a,d

如何删除每个字母之间的逗号？

2 - 我的代码不是很优雅,有没有办法将csv文件作为矩阵导入以选择最后一行,然后在javascript中使用像underscore.js这样的优雅库来删除重复项？

非常感谢

我有一个这样的程序代码。

我的界面是

public interface MyInterface {
        public void m1(String name);
        public void m2(int num);
}

我有一个实现上述接口的类。

    public class World implements MyInterface {
        public void m1(String name) {
               System.out.println(name);
        }

        public void m2(int num){
              System.out.println("Number is: "+num);
        }

        public static void main(String args[]) {
                MyInterface ob1  = new World(); //How it is instantiated
                MyInterface ob2  = new World();   //How this one too is instantiated
                ob1.m1("Jaguar"); 
                ob2.m2(5);

        }
}

using UnityEngine;
using System.Collections;

public class objectControl : MonoBehaviour {

    public char slected_item = 'F';
    public int selected_model = 0;
    public GameObject f,o,d;

    // Use this for initialization
    void Start () {
        f = GameObject.Find("f");
        o = GameObject.Find("o");
        d = GameObject.Find("d");
        selected_item = 'F';
    }

    // Update is called once per frame
    void Update () {
        selected_item = 'F';
        if (Input.GetKey(KeyCode.F)){
            selected_item = 'F';
            doSelectedAnimation();
        }
    }

    void doSelectedAnimation(){
        iTween.MoveTo(f,iTween.Hash("y",-3,"time",4));
    }

}

在我尝试从3个不同的地方访问"selected_model"的代码中.但不是它们有效.调试器给出以下错误.

Assets/Scripts/objectControl.cs(15,17):错误CS0103:当前上下文中不存在名称`selected_item'

我在下面有一个示例数据框.(1表示是,2表示否)

Age Range        Ans
10 - 20           1 
21 - 30           2
31 - 40           1
10 - 20           2
21 - 30           2 
21 - 30           1
21 - 30           2

期望的输出:

Age_Range        Yes        No
10 - 20           1         1
21 - 30           1         3
31 - 40           1         0

我怎么能在R？
