That looks a lot like the SQL/XML-style output plus a SOAP header. Below
is the output that I get from the SQL/XML function that I wrote. A simple
XSLT stylesheet should do the trick for you.

Btw., I also have an XSLT stylesheet that can make an HTML table out of
this output and I have a table function that can generate a virtual table
from this output.

=> select table2xml('select * from products');
