Re: XPath function after grouping

You grouped your Observation's by SiteNumber, so you can use this key for
sum() too:

<xsl:value-of select="sum(key('site_', SiteNumber)/Cond/value)"/>

Sums all Observation/Cond/value, which have the same current SiteNumber.

Result:

1:            19.4
130001:  10.2
2:              0
