Hi,
I'm observing a behaviour that seems weird to me but it might be correct
anyway.
If I compare values of attributes among sibling nodes then missing attributes
give me a little headache.
example:
<elem x="1"/>
<elem x="1"/>
<elem x="2"/>
<elem/>
<elem x="3"/>
If I group these elements into groups like this:
<xsl:for-each-group select="elem" group-starting-with="elem[@x !=
preceding-sibling::elem[1]/@x]">
....
Then the element with @x="2" and the element without the attribute will be in
the same group. So a the lack of the attribut is not interpreted as "having a
different value".
Is that normal ?
regards
