Remove carry return from xml signature

[Lopez Cantero, Sergio]

Hi, I've seen that every time you create a xmlsignature, nodes get "formatted" 
with a carry return at the end of the starting tag, p. ex:
<node>
<node2></node2>
</node>
Is there a way to deactivate this behavior? 
I need an output like:
<node><node2></node2></node>
Thanks
