XML读取节点属性
<?xml version= "1.0 " encoding= "gb2312 "?>
<processes>
<process id= "leave " name= "请假申请批准流程 ">
<activity id= "start " name= "开始 ">
<nextActivity id= "apply "/>
</activity>
<activity id= "apply " name= "申请 ">
<nextActivity id= "dept_manager_approve "/>
</activity>
<activity id= "dept_manager_approve " name= "部门经理审批 ">
<nextActivity id= "general_manager_approve " driveType= "manual "/>
<nextActivity id= "human_resource_record " driveType= "manual "/>
</activity>
<activity id= "general_manager_approve " name= "总经理审批 ">
<nextActivity id= "human_resource_record "/>
</activity>
<activity id= "human_resource_record " name= "人力资源部备案 ">
<nextActivity id= "end "/>
</activity>
<activity id= "end " name= "结束 ">
</activity>
</process>
</processes>
如果用这种方法，只是显示出各个节点属性的值，没有逻辑判断，我想通过一步一步判断显示出逻辑关系，但是不知道语句怎么写，初学，请教大家，帮个忙？
protected void Page_Load(object sender, EventArgs e)
{
XmlDocument xdoc = new XmlDocument();
xdoc.Load(Server.MapPath( "请假.xml "));
XmlNodeList nl = xdoc.SelectNodes( "//activity ");
{
string str = " ";
for (int i = 0; i < nl.Count; i++)
{
str= nl[i].Attributes[ "id "].Value ;
Label lb = new Label();
lb.Text = str;
Response.Write(lb.Text + "-> ");
}
}
}

你想做工作流引擎？ 用google查查资料吧。

不是每个Activity都有相应的NextActivity子节点么?
通过这个来连接
