how to differentiate parent and child tag while xml parsing in iphone

[xxhacker]

I am trying to get all tags values from xml and want to store them in a \[code\]NSMutableDictionary\[/code\]. I am having a problem to store the values in the \[code\]NSMutableDictionary\[/code\], I have a \[code\]NSMutableArray\[/code\] with a \[code\]NSMutableDictionary\[/code\] instead.
