Datacage: Introduced <dc:virtual-column name="colname" type="type" expr="XPath">
dc:virtual-column can be used to virtual add or replace a column named 'colname' to
the current result set. The value is determined by evaluating "XPath", the type is
determined by "type" (possible values: number, bool, node, nodeset, string. defaults to string).
Usage:
<dc:virtual-column name="c" type="number" expr="$a+$b">
<dc:for-each>
<dc:message>{$a} + {$b} = {$c}</dc:message>
</dc:for-each>
</dc:virtual-column>
table
a | b
--+--
1 | 2
3 | 4
will result in:
1 + 2 = 3
3 + 4 = 7
