From the last post, we saw the following results for parsing an XML dataset with about 450 simple elements in it 1,000 times:
Java: ~9 seconds

Java code:
Groovy code:
Note that this reduction in complexity happens almost everywhere I choose to use Groovy over Java. Of course there are myriad other ways I could have done this in Java (I even [...]
