求问一个用QXML解析SCD的问题，多谢。
在解析一个XML中的这样的一个部分的时候，1，<SDI name="SBOw">
2， <DAI name="ctlVal" sAddr="B37.AutoReclose.vbi_ar_bc">
3， <Val>0</Val>
4， </DAI>
5， <SDI name="origin">
6， <DAI name="orCat" sAddr="debug">
7， <Val>0</Val>
8， </DAI>
9， <DAI name="orIdent"/>
</SDI>
<DAI name="ctlNum"/>
<DAI name="T"/>
<DAI name="Test"/>
<DAI name="Check"/>
</SDI>
如下的代码，

在解析XML中的那个第7行的时候在下面//****出问题的行***//那会直接报错误退出来了，而在解析上面同样的第3行的时候却无问题，求教，谢谢。
