RE: Grouping siblings according to attribute sequence

same reposted with (I hope) proper indentation
Hi all,
I am using Saxonica\SaxonHE9.3N
I have the following source xml
<terms><term level="1" termid="10" > <value>ONE</value></term><term level="2"
termid="8" > <value>TWO</value></term><term level="3" termid="6"
> <value>THREE</value></term><!-- end of sequence = level number restart at 1
--><term level="1" termid="3" > <value>ONE BIS</value></term><term level="2"
termid="1" > <value>TWO BIS</value></term><term level="3" termid="58"
> <value>THREE BIS</value></term><term level="3" termid="45" > <value>THREE
TER</value></term><!-- end of sequence = level number restart at 1 --><term
level="1" termid="5" > <value>ONE FOURTH</value></term></terms>
Sequence always start with level = 1term are in sequence levels that are
always in increasing order, 1, 2, 3, etc.Last item in the sequence can be
duplicated (more that twice) there can be up to 5 levels max
I would like to get the following :
<terms><sequence> <value>THREE/TWO/ONE</value></sequence><sequence> <value>TH
REE BIS/TWO BIS/ONE BIS</value></sequence><sequence> <value>THREE TER/TWO
BIS/ONE BIS</value></sequence><sequence><value>ONE FOURTH</value></terms>

Thank you to help me get started.
Christian
