Help with Creating a Looping Procedure

Hi Below is the code I am using to parse an xml document.

I need help with creating a loop to read all the child nodes and then
all the values of those nodes. What I have at the monent works fine,
but I would like to cut the code way down by using a procedure.

Have you considered not writing this in Java? If all you're doing is
whacking a known input structure into CSV, you might try doing it in
XSLT, which is at least designed for the task.

Also, MJD has *three* suggestions for you. In no particular order,

#11927
A good approach to that problem would be to hire a computer
programmer.

#11928
First get a book on programming. Then read it. Then write the
program.

#11929
First ask yourself `How would I do this without a computer?' Then
have the computer do it the same way.
