上一部分有对窗口创建过程有一个大概的了解，这一部分主要讲述duilib对xml文件的加载及创建对应的子控件对象。从上一部分可知，这部分隐藏在Create函数中，源代码如下：
CControlUI* CDialogBuilder::Create(STRINGorID xml, LPCTSTR type, IDialogBuilderCallback* pCallback,
CPaintManagerUI* pManager, CControlUI* pParent)
{
//资源ID为0-65535，两个字节；字符串指针为4个字节
//字符串以SetDefaultFont(pFontName, pManager->GetDPIObj()->Scale(size), bold, underline, italic, shared);
}
}
else if( _tcsicmp(pstrClass, _T("Default")) == 0 ) {//其它的默认参数

以上代码就是根据xml根节点的第一层子节点（Font ，Default ）属性值，设置CPaintManagerUI对象的参数，同时加载根节点（Window ）窗口对象的属性设置窗口属性。xml例子如下所示：
最后的_Parse(&root, pParent, pManager)函数里，再根据xml子节点内容动态构建子控件树。放在下一部分讲解。
