Get a comma delimited string of nodenames.

Hi I have an xml like this:

<?xml version="1.0" ?>
<root>
  <data_field1>value1</data_field1>
  <data_field2>value1</data_field2>
  <data_field3>value1</data_field3>
  <data_field4>value1</data_field4>
</root>

I am trying to get back a string in the form:

"data_field1,data_field2,data_field3,data_field4"

Any help will be appreciated...
