Problem with parsing xml file

alphajin · by **alphajin** » Fri Feb 22, 2008 8:32 am

I have code to parse xml file. but it was puzzled that when I tried to get the attribute of any node with methode getAttributes() no matter this node had attr or not, this methode always return false.

I have the same code and parse the same xml file, it worked!

So can some guys explain this ?

Hello alphajin,

why not working with a SaxParser :?:

Tutorial:

Btw: System.out.println(...) doesn't work. In Android use LogCat instead.
Example: :arrow:

This code is well running in Java. In Android, you should change System.out.println to Log.i().

I am not farmilar with SaxParser, and I just want to know if it's bug in Android or not.

And thanks your help:)

Best regards,
Alpha

Hello alphajin,

sorry, never did xml-parsing like that.

Where do you import that functionality from. Maybe it was rewritten by Google and is placed in an android.xyz-package.
