RE: Group and compare data

2.0 solution:

<xsl:for-each-group
           select="*[starts-with(name(), 'aabnings')]"
           group-adjacent=".">
  <xsl:value-of select="concat(
        substring-after(name(current-group()[1]), 'aabningstider'),
        '-'
        substring-after(name(current-group()[last()]), 'aabningstider'),
        ' ',
        current-grouping-key())"/>
</xsl:for-each-group>

Needs a bit of refinement to avoid outputting Man-Man when the group size is
1.

One of the best use cases for group-adjacent I have seen!

In XSLT 1.0, you need to write a recursive template. It's tedious, so I'll
leave it to others.
