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? xml part <CheckBoxQuestion> <notice>in Europa kennen wir uns aus!</notice> <question>Welche der nachfolgenden Länder gehören zur EU?</question> <option number="1"> <text>Deutschland</text> <solution type="bool" points="4" valid_input="1"></solution> </option> <option number="2"> <text>Schweiz</text> <solution type="bool" points="5" valid_input="0"></solution> </option> <option number="3"> <text>Österreich</text> <solution type="bool" points="6" valid_input="1"></solution> </option> <option number="4"> <text>Türkei</text> <solution type="bool" points="7" valid_input="0"></solution> </option> </CheckBoxQuestion> xsl part <xsl:template match="CheckBoxQuestion" mode="table"> <xsl:apply-templates select="option" mode="check" /> </xsl:template> <xsl:template match="option" mode="check"> <xsl:variable name="correct_cells" select=". |following-sibling::option/solution[valid_input = 1]" /> <xsl:apply-templates select="$correct_cells" mode="check" /> <xsl:variable name="false_cells" select=". |following-sibling::option/solution[valid_input = 0]" /> <xsl:apply-templates select="$false_cells" mode="check" /> <xsl:variable name="correct" select="count($correct_cells) - count($false_cells)" /> <xsl:choose> <xsl:when test="$correct >= 0"> <td><xsl:value-of select="$correct" /></td> </xsl:when> <xsl:otherwise> <td>0</td> </xsl:otherwise> </xsl:choose> </xsl:template> -- NEU FÜR ALLE - GMX MediaCenter - für Fotos, Musik, Dateien...
