Question

I am new to the XML. Having a database in postgres, I would like to represent the data in XML format. How may i do that please?

Answer 1

You will have to use some form of application to read the data then parse it to the desired XML format. Here is an example of how to do it in PHP.

EDIT:

You can also use one of these functions table_to_xml, table_to_schema and table_to_xmlschema, etc. See the documentation.

Also have a look at this

A simple usage would be as follows:

SELECT table_to_xml('emp', TRUE, TRUE, '')

results

<emp xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <last_name>Blow</last_name>
    <emp_id>1</emp_id>
    <first_name>Joe</first_name>
    <dept_id>1</dept_id>
    <salary>10000</salary>
</emp>
