Question

I am using InputSource to parse a large xml file (1.2 mb). I need to keep this InputSource in memory. I do not want to keep loading it. What’s the best why to do this? I have tried using a singleton, but the Sax Parser complains that the document is missing an end tag after the 2nd time the object reference is accessed.

Any suggestions would be greatly appreciated.

InputStream ins = getResources().openRawResource(R.raw.cfr_title_index);    
InputSource xmlSource = new InputSource(ins);
MySinglton.xmlInput = xmlSource;

Thanks

Streams are “read once”. You should not plan to hang onto it. If you need its contents in memory, read them into an object or data structure and cache it.
