I am attempting to sum the certain groupings of nodes, based on the max and
min values contained in the nodes.
For example, if there are 20 node elements, sum the 5 largest and the other
15 values (ending with 2 values)
using POSITION(), I can determine what the 5 largest (or 15 other values
are), but I can't seem to determine how to sum these values.
my XML looks like
<items>
<item>
<value>6</value>
</item>
<item>
<value>3</value>
</item>
<item>
<value>7</value>
</item>
</items>
