查看API实现的方式

了解其返回值的解析方式

使用Java类进行封装并且实现返回xml的String到前台

查看API的实现方式，dhtmlx的官方文档中

C

true

true

从xml文档中便可得知：

1.Rows 节点当中存放的是Row的节点 一对多的关系，同时属性parent表示的是Row节点id的属性表示的上下级的关系

2.Row节点当中有Userdata的属性 是一对多的关系，可以放入多个值来表示在列当中不能显示的一些值，例如当前行的ID

3.Row节点当中含有Cell节点，是一对多的关系 Cell表示的是每行当中的单元格

根据上面的分析，开始封装代码

Row.java

private List cells ;

private String id="";

private String xmlkids="";

该行对象当中存放的是cells，也就是单个单元格，id表示当前行的id,xmlkids表示是否有子节点,1表示有子节点
