Re: [xsl] different evaluations on sibling elements ...

okay I tried this but mixed up the relative path expressions and the location 
step …

But still puzzling:
The change brought me to:
"XPTY0004: A sequence of more than one item is not allowed as the first 
argument of"

So I changed the lines to be:

<xsl:variable name="next" 
select="dateTime($entry/following-sibling::entry/isodate, 
$entryfollowing-sibling::entry/time)"/>
<xsl:variable name="next" 
select="dateTime($entry/following-sibling::entry[1]/isodate, 
$entry/following-sibling::entry[1]/time)"/>
to only get the first following-sibling. Which brought me the following error:
"XPTY0004: Cannot divide two durations of different type"

pointing to the line 
<xsl:sequence select="($next - $this) div xs:duration('PT1H')"/>

Here I have a hard time understanding the formats - especially since I did not 
use the XSLT 2.0 dataTime so far. Is't $this, $next simply in ISO8601 date 
format of the form YYYY-MM-DDTHH:mm:ss - if so the subtraction already should 
already not be okay?

Yes, sorry, a mistake I often make: within the function, all the relative 
path expressions should start with $entry. So

<xsl:variable name="this" select="dateTime($entry/isodate, $entry/time)"/>
<xsl:variable name="next" 
select="dateTime($entry/following-sibling::entry/isodate, 
$entryfollowing-sibling::entry/time)"/>
