formatting attributes

Have coded a template that outputs an element with 4 attributes

 <elem attr1="{blah}"
           attr2="{moreBlah}"

etc

and this mirrors the output...that is the attributes are spread over 4
lines for each element.

I wanted one line per element and accomplished this by doing an xmlllint on
the output with the format  flag switched on. However I  was wondering
whether same was not achieveable from XSLT, or will it religiously
replicate the newlines from the template rule.
