[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] [no subject]![[no subject]](/images/get_stylus.gif) For instance, I have the following XML data:
<food>
<item type="fruit" name="apple" rotten="6" total="10"/>
<item type="fruit" name="orange" rotten="2" total="10"/>
<item type="fruit" name="pear" rotten="1" total="4"/>
<item type="vegetable" name="carrot" rotten="0" total="5"/>
<item type="vegetable" name="potato" rotten="1" total="2"/>
</food>
To which I apply a stylesheet to get a nice table output. I know how to get
to overall sums, but I don't know how to get the group/inner sums (denoted
by '?'):
type name rotten total percent
fruit
apple 6 10 60
orange 2 10 20
pear 1 4 25
total ? ? ?
vegetable
carrot 0 5 0
potato 1 2 50
total ? ? ?
total 10 31 32.3
Here are some assumptions that can be made about the data:
* The items are guaranteed to be sorted by the "type" attribute.
* I don't know the possible values of "type" beforehand.
* Its format cannot be changed.
Also:
* I am using XSLT 1.0, but upgrading to 2.0 might be possible (I'm not
sure).
* I am using python 2.4 with libxml2 and libxslt.
Here's the stylesheet I have now (that generated the above table):
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html><body><table>
<tr>
<td>type</td>
<td>name</td>
<td>rotten</td>
<td>total</td>
<td>percent</td>
</tr>
<xsl:for-each select="//item">
<xsl:if test="not(preceding-sibling::*[1]/@type=@type)">
<tr><td><xsl:value-of select="@type"/></td></tr>
</xsl:if>
<tr>
<td></td>
<td><xsl:value-of select="@name"/></td>
<td><xsl:value-of select="@rotten"/></td>
<td><xsl:value-of select="@total"/></td>
<td><xsl:value-of select="format-number(@rotten div @total *
100,'##.#')"/></td>
</tr>
<xsl:if test="not(following-sibling::*[1]/@type=@type)">
<tr>
<td></td>
<td>total</td>
<td>?</td>
<td>?</td>
<td>?</td>
</tr>
</xsl:if>
</xsl:for-each>
<tr>
<td>total</td>
<td></td>
<td><xsl:value-of select="sum(//item/@rotten)"/></td>
<td><xsl:value-of select="sum(//item/@total)"/></td>
<td><xsl:value-of select="format-number(sum(//item/@rotten) div
sum(//item/@total) * 100,'##.#')"/></td>
</tr>
</table></body></html>
</xsl:template>
</xsl:stylesheet>
Thank you,
