When I write some scripts to learn I often use "XSI collection" but in a
deadline I forget my new knowledge :-)
Thanks kim !
2005/6/15, kim aldis <kim@(protected)>:
you're looping through a list of items but changing that list as you loop
through it so it's count and item order is changing as you go. There's a few
ways to deal with this, either push the items you want to delete onto an
array in the main loop then delete the items in that array after the loop,
or make a copy of the selection first and loop through that.
Try this:-
var oColl = new ActiveXObject( "XSI.Collection" );
oColl.items = selection; // selected items into collection
// loop through the collection. No reason not to use a traditional integer
loop for this but this is faster.
//
for ( var f=new Enumerator( oColl ); !f.atEnd(); f.moveNext() ) {
var oItem = f.item();
if ( oItem.type != "FileInputOp" ) {
removefromselection( oItem );
}
}

Subject: FX tree : Select file input node only
Hi List,
I need to select all the file input nodes from a fxtree.
The script I write below seems to remove randomly some nodes ???
I don't understand why ?
//All the Fx tree nodes are selected.
var oSel = Selection;
for(i=0;i<oSel.count;i++)
if(oSel(i).type != "FileInputOp")
{
RemoveFromSelection(oSel(i))
}
logmessage("only file input nodes are selected !")
Any idea ?
Cheers,
