Text node evaluation

If you want to fill the text node value dynamically, you must create a value for it in the corresponding rule, for example:

<tdt:rule path="/data/day/station"> <tdt:value key="text()">/data/details/name</tdt:value> </tdt:rule>

If the transformation rule contains an XPath expression that evaluates to a value for the text node, then the value is overwritten by the evaluation result (deleted if the result is empty).

If the transformation rule does not contain an XPath expression that evaluates to a value, then the value is left as it is in the data template (no value or static value).

Note:

The XPath expression must evaluate to a simple value (string, number, boolean), or a node-set with 0 or 1 value.
