Re: [xsl] Conditional in-context nodeset variables

["Vyacheslav Sedov" <vyacheslav.sedov@xxxxxxxxx>]

yep - it small simplified part of big code (more precisely - just testcase),
i don`t use xsl:...group since it make my code behavior like it use pull model,
but i am trying to use push model - maybe it wrong & i just not
familiar with grouping,
i feel myself with this task like cow on ice :)

guess i need take pen and paper and first perform this task on it -
look like it not solved mentally :)

by the way  - in my case i began use select="if () then () else ()"
structure - look like it work as expected,
i am not fan of several-lines long attributes but at least it work

with best wishes,
Slav
