Is there a way to control groovy's MarkupBuilder's output and filter out the newline characters? I have code like below:

import groovy.xml.MarkupBuilder

def writer = new StringWriter()
def xml = new MarkupBuilder(writer)
xml.basket(){
    fruit (type:"apple", 1)
    fruit (type:"orange", 2)    
}  

which invariably outputs:

<basket>
  <fruit type='apple'>1</fruit>
  <fruit type='orange'>2</fruit>
</basket>

I'd really like it in a single line:

<basket><fruit type='apple'>1</fruit><fruit type='orange'>2</fruit></basket>
