Подскажите как вычислить сумму??
Есть код:
<xsl:for-each select="Record">
<tr>
<td align ="left" style="font-size: 12pt;background-color: white; color : black;" > <xsl:value-of select="@DateTime"/></td>
<td align ="left" style="font-size: 12pt;background-color: white; color : black;" > <xsl:value-of select="@ValueCol1"/></td>
<td align ="left" style="font-size: 12pt;background-color: white; color : black;" > <xsl:value-of select="@ValueCol2"/></td>
<td align ="left" style="font-size: 12pt;background-color: white; color : black;" > <xsl:value-of select="@ValueCol3"/></td>
<td align ="left" style="font-size: 12pt;background-color: white; color : black;" >
<xsl:value-of select="format-number((number(@ValueCol1)-number(@ValueCol2))*number(@ValueCol3), '#####.###')"/> </td>
</tr>
Как это можно сделать с выражением: (number(@ValueCol1)-number(@ValueCol2))*number(@ValueCol3)
