[xsl] Re: Need some help with an XPath

["Dimitre Novatchev" <dnovatchev@xxxxxxxxx>]

Use:

/*/*/service[
                   not(@servId = /*/*[1]/*/@servId
                      and
                         @servId = /*/*[2]/*/@servId
                      and
                        @servId = /*/*[3]/*/@servId
                         )
                    ]
