求问一个用QXML解析SCD的问题，万分谢谢您。
在解析一个XML中的一段的时候出现了错误，帮忙看下，谢谢了。这个代码原先是VC6+QT3上面的，我移植到VS2010+QT4下面，XML的前面一部分都能正常解析得到，就在解析下面的片断的时候，跳出那个我标注了的中括号的时候报错误。
XML片断：
<DOI name="Mod" desc="模式">
<DAI name="stVal"/>
<DAI name="q"/>
<DAI name="t"/>
<DAI name="ctlModel">
<Val>0</Val>
</DAI>
</DOI>
代码片断，就是用来解析那些DAI的。错误处标明了。

错误图片如下：
堆栈空间情况如下：
还有一个问题请教，就是为什么同样的XML，我用XERCES解析比用QT解析慢好多？万分感谢帮忙回答问题的人。 --------------------编程问答--------------------
<DAI name="ctlModel">
<Val>0</Val>
</DAI>
这个值0是能得到的。 --------------------编程问答-------------------- 其中，
#define CODEU(x) x.toLocal8Bit().data() --------------------编程问答-------------------- 晕，没一个人回啊。哎。
补充：移动开发 , Qt
