Re: Copy and group XML

Good day, could someone please tell me what I'm doing wrong here.

I'm trying to copy a XML document with 'play' as route. While doing so
I need to group the 'scene' elements under 'act'. The xsl below works
(almost), but throws out anything that falls under play, but outside
of a scene. I need to preserve (copy) elements that are outside of
'scene'.

<xsl:for-each-group select="*" group-adjacent="(@act, '?')[1]">
<xsl:choose>
<xsl:when test="@act">
<act>
<xsl:apply-templates select="current-group()"/>
</act>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
