Hi Andrew,
And my out put is an HTML table table with four columns:
Col 1: the item id
Col 2: the a value
Col 3: the b value
Col 4: the product of a and b
Can I sort my output by the fourth column? I know how to sort by the
item id, a, or b, but don't know what I need to do to properly
address the calculated value "column".
You can sort by any expression you like by putting it in the select
attribute of xsl:sort. In this case you need:
<xsl:for-each select="item">
<xsl:sort select="a * b" data-type="number" />
<tr>
<td><xsl:value-of select="@id" /></td>
<td><xsl:value-of select="a" /></td>
<td><xsl:value-of select="b" /></td>
<td><xsl:value-of select="a * b" /></td>
</tr>
</xsl:for-each>
Cheers,
Jeni
