[4.1] [patch] Fix bug in xml transformer

[Matthias Klose]

Fix bug in xml transformer, needed to fix eclipse's handling of its
configuration files, proposed by Michael Koch.

AFAIU, this patch form classpath trunk should not be applied to the
trunk, but to to the 4.1 branch only and mentioned in
libjava/classpath/ChangeLog.gcj.

Ok to apply?
