Re: [xsl] Better Way to Group Siblings By Start/End Markers?

[David Carlisle <davidc@xxxxxxxxx>]

<xsl:for-each-group select="w:r"
group-adjacent="
string(self::*[w:fldChar[@w:fldCharType = 'begin' or @w:fldCharType =
'end']] or 
(self::*[preceding-sibling::*/w:fldChar[@w:fldCharType = 'begin']] and
self::*[following-sibling::*/w:fldChar[@w:fldCharType = 'end']] and
count((self::*[preceding-sibling::*/w:fldChar[@w:fldCharType =
'begin']])[1]/(*[following-sibling::*/w:fldChar[@w:fldCharType = 'end']])[1]

(self::*[following-sibling::*/w:fldChar[@w:fldCharType = 'end']])[1]) = 1

I think you can just do


<xsl:for-each-group select="w:r"
group-adjacent="w:fldChar/@w:fldCharType[. = ('begin','end')]"
>
..
<xsl:choose>
when  current-grouping-key()='begin'
 you are on a begin
when  current-grouping-key()='end'
 you are on an end
when  current-grouping-key()='' and preceding-sibling::*[1]/w:fldChar/@w:fldCharType='begin'
 you are inside a begin-end field
when  current-grouping-key()='' and preceding-sibling::*[1]/w:fldChar/@w:fldCharType='end'
 you are outside a begin-end field



That puts your fields into three groups (begin, interior, end) rather
than 1, but depending on what you are doing next you can either handle
that in processing or do an easier second pass to merge these groups.
