Hi,

Is it possible to convert / (re)store a column that contains xml (see
below) into real table in a trigger, using contrib/xml2?

The reason is that an application stores a xml blob in a column but we
need the data in a real table for a third party report generator. So I
want to use a trigger that, upon insert, update or delete, moves the
data into that table.

The XML looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<data>
	<field>
		<name>field1</name>
		<value>value1</value>
	</field>
	<field>
		<name>field2</name>
		<value>value2</value>
	</field>
</data>

And I have a table with the (text) columns field1 and field2.

Any pointers to a solution is really appreciated (solutions also ;-))

TIA
