Team,
I have a sequence of strings which are all 'ok' or 'fail' where I
want to force the case of all of them.
Actually, it looks like you have a sequence of nodes in $states, not strings.
When I say they are all 'ok' or 'fail' I actually mean they may be
'ok', 'OK', 'Ok', 'Fail', 'fail', 'FAIL' etc.
I use
<xsl:variable name="ok-fails-1" select="$states/normalize-space(column[7])" />
to extract the sequence from my original xml.
If I say
<xsl:variable name="ok-fails-1-lc" select="lower-case( $ok-fails-1 )" />
then I get told that lower-case can only take a string as its
parameter, not a sequence.
Can anyone suggest how I might process my sequence to return a
sequence but have each entry passed through lower-case.
$states/lower-case(normalize-space(column[7]))
I remind my students in class that the "/" in "$nodes/expr" is an
abbreviation for:
for $n in $nodes return expr($n)
... which is exactly what you did in setting your first variable. I
just took it one step further.
I thought maybe I could pass it as a parameter to a moded
apply-templates, but then I get warned that select needs a node, not
a string, as its @select attribute.
That shouldn't be necessary if the input is as simple as you imply.
Subsequently I do distinct-values on it and the result of that I
want only to contain 'ok' or 'fail', with no case variations remaining.
The sequence above would be satisfactory input to distinct-values().
I hope this helps.
