Adding xml element values

[acsooley]

Have a xml doc like:

<home>
<tag>4</tag>
<tag>6</tag>
<tag>5</tag>
<tag>5</tag>
<tag>10</tag>
</home>

Is there a way to add the values in xsl to give me the total of tag? So it would output 30?

[tt]<xsl:template match="home">
<xsl:value-of select="sum(//tag)" />
</xsl:template>[/tt]

Sorry I should have done this differently:

<home>
<ppl>
<var>a</var>
<tag>4</tag>
</ppl>
<ppl>
<var>c</var>
<tag>6</tag>
</ppl>
<ppl>
<var>a</var>
<tag>5</tag>
</ppl>
<ppl>
<var>d</var>
<tag>5</tag>
</ppl>
<ppl>
<var>c</var>
<tag>10</tag>
</ppl>
</home>

So if I am doing a search for the c var I want the total of the tag tags? Which would be 16. I would also like to divide it if it is possible. So get the total of 16 and divide by 2 to get 8.

Any help?

Thanks
Adam

<xsl:value-of select="sum(//tag[preceding-sibling::var='c'])" />
</xsl:template>[/tt]
The rest, go figure out yourself.
