Question

I’m working on a school assignment and I’ve been completely stumped with this step.

I need to find the sum of all elements who attribute value falls between two numbers, in this case greater than 9 and less than 18. I’ve spent an hour trying different combinations and done of them work, I can’t find any example in the book which has this. Can someone help point out what I’m doing wrong or nudge me i the right direction?

Here’s the snippet of the XML and XSLT.

<course>
 <par holeNumber="1">4</par>
 <par holeNumber="2">4</par>
 <par holeNumber="3">5</par>
 <par holeNumber="4">3</par>
 <par holeNumber="5">4</par>
 <par holeNumber="6">4</par>
 <par holeNumber="7">5</par>
 <par holeNumber="8">3</par>
 <par holeNumber="9">4</par>
 <par holeNumber="10">4</par>
 <par holeNumber="11">5</par>
 <par holeNumber="12">4</par>
 <par holeNumber="13">3</par>
 <par holeNumber="14">4</par>
 <par holeNumber="15">5</par>
 <par holeNumber="16">4</par>
 <par holeNumber="17">3</par>
 <par holeNumber="18">4</par>
</course>

<xsl:template match="par">
<td><xsl:value-of select="." /></td>
<xsl:choose>
    <xsl:when test="./@holeNumber">
        <td class="sub"><xsl:value-of select="sum(@holeNumber &gt; 9)" /></td>
        <td class="final"></td>" /></td>
        <td class="final"></td>
    </xsl:when>
    <xsl:when test="1">

    </xsl:when>
    <xsl:otherwise>

    </xsl:otherwise>
</xsl:choose>

Answer 1

/course/par[@holeNumber <= 18 and 9 <= @holeNumber]

You can use this in your match, or you can use it just to get your sum:

sum(/course/par[@holeNumber <= 18 and 9 <= @holeNumber])

NOTE: This is using <= instead of just < to get both 18 and 9. Remove the = if you don’t want them included.
