Hi!
I posted the problem recently and actually got it working - until now. For
some mysterious reason it suddenly does throw an
ConcurrentModifcationException in my Visitor (second for loop):
class Foo
{
private static final class HeisetextLegacyVisitor extends VisitorSupport
{
private static final String HEISETEXT = "heisetext";
public void visit( Element node )
{
if( node.getName().equalsIgnoreCase( HEISETEXT ) )
{
int index = -1;
// hard to touch the tip of your nose when you are
wankered...
List<Element> l = node.getParent().elements();
for( int i = 0; i < l.size(); i++ )
{
if ( l.get( i ).getName().equalsIgnoreCase(
HEISETEXT ) )
{
index=i;
break;
}
}
assert index != -1;
for ( Iterator<Element> it = node.elementIterator();
it.hasNext(); )
// HERE's where the exception is thrown
l.add( index++, (Element)it.next().detach() );
l.remove( index ); // heisetext
}
}
}
private static final Visitor LEGACY = new HeisetextLegacyVisitor();
public void go()
{
dom.accept( LEGACY );
}
}
Does anybody see why this exception is thrown here?
