Hey Tom
Thank you Thank you very much for yr clean answer, It
works well !
The code posted is a fragment from the long program
it transfers schema to cobol or other language, which
requires ready to accpet xml message in sequence at
run time.
Tom, Could you extend your further help
what if I can't evaluate by string->
not(start-with(@ref, 'GRP')), but need to judge from
whether the element can apply another templates.
because there are lots different groups, and naming by
different people, etc.
such as , I add a GRP xs:element in the schema which
is tailor for this 'GRP2'
<xs:element name="GRP2">
<xs:complexType>
<xs:sequence>
<xs:element ref="GRP-for-mail"
maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
Is it possible to still keep the key definition ?
many thanks
Paul

Hi Paul,
I don't quite understand what you're doing, but is
this any use? It gives
something akin to what you want, but I'm sure it's
more complicated...
<xsl:key name="byGRP"
match="xs:element[not(starts-with(@ref, 'GRP'))]"
use="generate-id(preceding::xs:element[starts-with(@ref,
'GRP')][1])"/>
<xsl:template match="/xs:schema/xs:element">
<xsl:for-each
select="//xs:element[starts-with(@ref, 'GRP')]">
<xsl:variable name="me" select="generate-id()"/>
Group is <xsl:value-of select="@ref"/> :
<xsl:for-each select="key('byGRP',$me)">
<xsl:value-of select="@ref"/> Starts
</xsl:for-each>
<xsl:for-each select="key('byGRP',$me)">
<xsl:value-of select="@ref"/> Ends
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

Subject: Re: [xsl] grouping sequence question
Hi
I'm doing stylesheet for schema. had stuck by the
sequence grouping for several days
As I checked the grouping methodology on
http://www.dpawson.co.uk/xsl/sect2/N4486.html and
http://www.jenitennison.com/xslt/grouping/
still not work out my problem by applying those
modules. And I tried to change the bottom
<xsl:apply-templates>
select="xs:element[starts-with(@ref, 'GRP')]"
mode="group"/> to
<xsl:for-each select ="xs:element |
xs:choice/xs:element | xs:sequence/xs:element |
xs:choice/xs:sequence/*">
<xsl:apply-templates select="key('at',
generate-id())[generate-id() !=
generate-id(current())]" mode="group"/>
</xsl:for-each>
with a new key:
<xsl:key name="at" match="xs:element"
use="generate-id((preceding-sibling::xs:element |
self::xs:element | self::xs:sequence/xs:element)
)"/>
but output below is not what I desired:
starts
PET starts
MAID starts
ends1
PET ends
MAID ends
---11
NAME starts
NAME ends
PHONE starts
PHONE ends
E-MAIL starts
E-MAIL ends
MAID starts
MAID ends
I think the key "at" have some problem or it might
need to add a new template for the key "at", I
can't
figure it out. Highly appreciate if anyone can
kindly
give any thoughts to me !!
