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 !!

Hi
Further to group sequence problem(xsl for schema),
Is
it possible to adjust the key setting, to let
PET starts1
MAID starts1
PET ends1
MAID ends1
occur after name, before phone(in sequence)
thanks !!
