Re: [xsl] Pattern notation for preceding-sibling

["Michael Kay mike@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I would write

/foo/E/preceding-sibling::*[self::A | self::N]

If A and N have something in common that leads to this kind of expression
being meaningful, then in a schema-aware world it's quite likely that you can
make them members of the same substitution group G, in which case you can
write

/foo/E/preceding-sibling::schema-element(G)

And another possibility is

/foo/E/preceding-sibling::*[not(self::B)]
