RE: [xsl] Create Table

["Michael Kay" <mike@xxxxxxxxxxxx>]

There's a shortcut for this kind of expression that's worth knowing:

if (data[@section='changes' and @field=$x]) then
                 data[@section='changes' and @field=$x] else ' '">

can be rewritten as

(data[@section='changes' and @field=$x], ' ')[1]

That's assuming that the expression data[@section='changes' and @field=$x]
selects 0-or-1 elements.
