hii大家好，sowmya是全新的android系统请帮助我，解析下面的本地xml文件，但只得到第一个问题的输出（第一组标签），但第二个问题（重复标签）我没有得到,, thanx提前在android中解析本地XML文件
<innertag sampleattribute="innertagAttribute">
<mytag>1) How did u find the hotel house keeping overall in the year </mytag>
<innertag sampleattribute="innertagAttribute">
<mytag>2) How do u rate the hotel house keeping overall in the year </mytag>
</outertag>

解析的主要思想是提取一些标签之间的数据，这些标签通常重复多次。此外，您拥有本地或远程xml数据源的事实不需要不同的分析器。您的问题似乎是您通过解析检索数据后存储数据的方式。 – Adinia 2011-01-11 15:06:45
