Re: how to view xml output file

All the method call analyses (should) build an InvokeGraph, a common
representation. It seems to me that this would be a more general way of
obtaining this information. Here is the code that I would use:

if( !Scene.v().hasActiveInvokeGraph() ) {
    // InvokeGraphBuilder uses CHA, but other sources of InvokeGraphs
    // are possible
    InvokeGraphBuilder.v().transform( phaseName + ".igb" );
}
InvokeGraph ig = Scene.v().getActiveInvokeGraph();

List targets = ig.getTargetsOf( stmt );
// where stmt is the Stmt containing the InvokeExpr
//       targets gets a list of SootMethods that are possible targets
//       of the InvokeExpr
