Question

Is there any way to get the amount of bytes read in by the XMLStreamReader, I am using a java.io.FileReader which is passed into the factory that creates the xml reader. I’m doubting this is possible with the XMLStreamReader but any work around is great.

Answer 1

Assuming you are doing somthing like this:

final XMLInputFactory inputFactory; final XMLStreamReader reader; final InputStream     stream;  inputFactory = XMLInputFactory.newInstance(); stream       = new FileInputStream(file); reader       = inputFactory.createXMLStreamReader(stream); 

You would do something like this:

final XMLInputFactory     inputFactory; final XMLStreamReader     reader; final InputStream         stream; final CountingInputStream countingStream;  inputFactory   = XMLInputFactory.newInstance(); stream         = new FileInputStream(file); countingStream = new CountingStream(stream); reader         = inputFactory.createXMLStreamReader(countingStream); 

Where CoutingInputStream is a class that you would need to write/find that keeps track of the number of bytes being read from the underlying InputStream object.
