That should be:
#if( "$!items.getAttributeValue('required')" != "" )
Or just $!items.getAttributeValue('required') if you don't mind
showing empty strings.
Or if you really want to clean up the look:
public class AltTool {
public Object empty(Object val, Object alt) {
return (val == null || val.toString().length() == 0) ? alt : val;
}
}
context.put("alt", new AltTool());
$alt.empty($item.getAttributeValue('required'), 'No')
