1. 准备一个xml文件
xmlmenu
1<menu>
2 <menuitem name="系统管理" assemblyname="" formtag="false" addtoolbar="false">
3 <menuitem name="权限管理" shortcut="" image="" assemblyname="" formtag="false" addtoolbutton="false">
4 <menuitem name="系统权限管理" shortcut="" image="password.png" assemblyname="hustcad.inteplm.winui.frmsysright,inteplm.tyrightwinui"
formtag="true" addtoolbutton="false"/>
5 <menuitem name="权限规则定义" shortcut="" image="right.png" assemblyname="hustcad.inteplm.winui.frmrightrule,inteplm.tyrightwinui"
formtag="true" addtoolbutton="false"/>
6 <menuitem name="权限日志" shortcut="" image="doc_yellow_edit.png" assemblyname="hustcad.inteplm.winui.frmrightlog,inteplm.tyrightwinui"
formtag="true" addtoolbutton="false"/>
7 </menuitem>
8</menu>
2.准备一个xml schemal文件来验证xml文件
<?xml version="1.0" encoding="utf-8"?>

这里面用到了delegate，最重要的函数是加载菜单的函数和onpluginclick函数。
使用这个框架可以动态增加任意的层次的模块。
微软的cab 使用resigster site方式来增加模块，感觉不是很方便。
以上就是一个简单的基于xml的模块集成框架的内容。
