Re: Grouping
Thank you Martin!
This is the perfect solution for the overall stylesheet. Even if it's
not as readable as the solution with a function, it requires no
knowledge about the special grouping logic when applying templates
somewhere in the rest of the stylesheet.
And it's _way_ more understandable than the stuff I came up with.
Wish you a good evening.
Best regards
Christoph

The group-wrap should be performed for sequences of <points> of @type =
'1'. <Points> of other types and completeley other nodes should not be
grouped.
Another approach not using grouping with for-each-group is trying to key
on the generated id of the first node in the group; usually that leads
to patterns that make my head spin but so did your original code:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
B B B B xmlns:xs="http://www.w3.org/2001/XMLSchema"
B B B B exclude-result-prefixes="#all"
B B B B version="3.0">
B <xsl:key name="point-group"
B B B B B B B B B B match="point[@type = 1 and
preceding-sibling::*[1][self::point[@type = 1]]]"
B B B B B B B B B B use="generate-id(preceding-sibling::point[@type =
1][not(preceding-sibling::*[1][self::point[@type = 1]])][1])"/>
B <xsl:mode on-no-match="shallow-copy"/>
B <xsl:output method="xml" indent="yes"/>
B <xsl:template match="point[@type =
1][not(preceding-sibling::*[1][self::point[@type = 1]])]">
B B B B B <group>
B B B B B B B B B <xsl:copy-of select="., key('point-group', generate-id())"/>
B B B B B </group>
B </xsl:template>
B <xsl:template match="point[@type = 1 and
preceding-sibling::*[1][self::point[@type = 1]]]"/>
</xsl:stylesheet>
