XSLT key not available inside template (using note-set array) - xslt

Question

I created an XLT document with an array of values for each of the hour of the day. I loop through this array by creating a variable using node-set.
I have a key created that holds the total counts for each hour called key-hours. However, when I pass it a value from the $hour-array variable, it does not display the corresponding total count.

This results in the total column not been populated with the actual sum of totals. Here is what that looks like.
Here is a fiddle of the result for you to play with.

Answer 1

I would suggest to change the context by doing
<xsl:template match="hour" mode="test-list">
<xsl:apply-templates select="$main-doc" mode="test-list">
<xsl:with-param name="h" select="."/>
</xsl:apply-templates>
</xsl:template>
<xsl:template match="/" mode="test-list">
<xsl:param name="h"/>
<xsl:variable name="grand-total" select="sum(/Records/Record/Total)" />
<xsl:variable name="row-total" select="sum(key('key-hour', $h)/Total)" />
<xsl:variable name="pct" select="($row-total div $grand-total)*100" />
<tr>
<xsl:choose>
<xsl:when test="$pct > 50">
<xsl:attribute name="class">red-90</xsl:attribute>
</xsl:when>
<xsl:when test="$pct > 40">
<xsl:attribute name="class">red-70</xsl:attribute>
</xsl:when>
<xsl:when test="$pct > 30">
<xsl:attribute name="class">red-50</xsl:attribute>
</xsl:when>
<xsl:when test="$pct > 20">
<xsl:attribute name="class">red-30</xsl:attribute>
</xsl:when>
<xsl:when test="$pct > 10">
<xsl:attribute name="class">red-10</xsl:attribute>
</xsl:when>
</xsl:choose>
<td class="test">
<xsl:value-of select="$h"/> (<xsl:value-of select="key('key-hour',$h)"/>)
</td>
<xsl:for-each select="$unique-tube-list">
<xsl:variable name="total" select="key('key-tube-hour',concat(current(),'::',$h))/Total"/>
<xsl:choose>
<xsl:when test="$total">
<td><xsl:value-of select="format-number($total,'###,###')" /></td>
</xsl:when>
<xsl:otherwise>
<td>0</td>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
<td>
<xsl:value-of select="format-number(sum(key('key-hour',$h)/Total),'###,###')" />
</td>
</tr>
</xsl:template>
Needs <xsl:variable name="main-doc" select="/"/> and where you process the hours change the apply-templates to <xsl:apply-templates select="$hour-array/hour" mode="test-list"/>
