RE: [xsl] FW: Trying to translate code with specific values into variables to do a count

["Michael Kay" <mike@xxxxxxxxxxxx>]

You start with

preceding::table-wrapper[ends-with(@km,'Ta.A')]

and you want the element name to be variable. So you replace table-wrapper
with *[name()=$x]. That gives you

preceding::*[name()=$x][ends-with(@km,'Ta.A')]

not

preceding::*[name()=$x[ends-with(@km,'Ta.A')]]

because the ends-with predicate qualifies the element *, not the variable
$x.
