my problem is different, I need to match a node that have NOT a
particular attribute.
Imagine a sequance of node of the same type which can have attributes or not.
I need to perform a first match and if an particular attribute is
absent I will have to perform a second match, otherwise the first
match is enough.

For example:

   <B a="a">hello2</B>
   <B a="a" b="b">hello3</B>
   <B b="b">hello4</B>

I match the first two "B" nodes as is (the XSLT rewrite them without
for the third "B" node, since it lacks the "a" attribute, the XSLT
will perform a second match looking for the next "B" node.

Is it possible to match the absence of an attribute with xsl?
