I guess, the following XSL will be appropriate --
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>
<xsl:template match="/CheckBoxQuestion">
<xsl:variable name="right"
select="count(option/solution[(_at_)valid_input = '1'])" />
<xsl:variable name="wrong"
select="count(option/solution[(_at_)valid_input = '0'])"/>
Total points: <xsl:value-of select="$right -
$wrong" />
</xsl:template>
</xsl:stylesheet>

hallo,
sorry about my terrible english.
my problem is to check out a check box question, to
see if the answer is
right or false.
the given answer of the student to the question is
given in the solution tag
(right =1 wrong =0), the valid_input presents the
right answer the teacher
has given. to see how many right answers are given,
my idea is counting the
correct cells and counting the wrong cells. the
variable correct should give
out the difference of the right and wrong answers.
it should be a number
written into a cell of a table.
is this possible?
