It would have helped if yo'd supplied input file, but whatever.
your $volume, $issue and $journal variables apparently hod data for all
teh items. You apparently want to just return the volume and issue
for the node that you are processing. Confusingly you are using
suingular variable names for (eg) $volume even though this holds
multiple nodes, whereas you are using the plural name $nodes for the
$nodes variable which holds a single node.
without any input hard to check these paths but you seem to want
and similarly for issue etc.
have to use .. here as $ad2 (despite its name) stores head eleemnts not
ad elements, so you first need to go up to the parent ad, then down to
let $ad2 := $ad//ad/head[contains(., 'muscle') or contains(., upper-case('muscle'))]
It's pointless calling a function on a string literal, the above could more
easily be written
let $ad2 := $ad//ad/head[contains(., 'muscle') or contains(., 'MUSCLE')]
it wouldn't find Muscle, don't you want
let $ad2 := $ad//ad/head[contains(upper-case(.), 'MUSCLE')]
which will find muscle in any case, or better to compare using
a case-blind collation if your system offers such a collation.
