RE: [xsl] problem with boolean AND expression [false AND false ->true] in xslt2.0

["Robby Pelssers" <robby.pelssers@xxxxxxxxx>]

Thx Michael,

Using the schema aware processor would probably only make sense if I
were to apply a single xslt on an xml document referencing a schema.
However, I'm using cocoon pipelines to process 1 document where the
intermediate results no longer conform to the original schema so these
kinds of mistakes seem unavoidable.  Unless you have a good proposal for
this particular way of working?

Many thx for spotting this stupid error ;-)

Robby

Check your spelling of "entry" vs "Entry". XML is case-sensitive.

To avoid such errors, consider using schema-awareness, which will check
the
names appearing in path expressions against the names that are valid
according to the schema.
