Inside the predicate it has to be 'or'. '|' correctly only means UNION not 'or', but it can be read so.

So either

"doc[N1='xxx' or N2='yyy']"
all <doc>, which have <N1> as child with value 'xxx' or <N2> with 'yyy'

or

"doc[N1='xxx'] | doc[N2='yyy']"
all <doc>, which have <N1> with 'xxx', united with all <doc>, which have <N2> with 'yyy'
If a node fulfills both predicates it is only once in the nodeset too, because one node can not occure twice in a nodeset.


I hope it is to understand - or Jeni must help.

Joerg

Hi

I try to put a | inside a predicate but it doesn't work.
<xsl:apply-templates select="doc[N1='xxx' | N2='yyy']"/>

Putting | outside the predicate works. <xsl:apply-templates select="doc[N1='xxx'] | doc[N2='yyy']"/>

Why is there a difference?

Bernward
