Writing an xml document

[dptalt]

I want to make changes to and xml document using the xmltextreader and xmltextwriter. The changes to write back to the xml document are stored in a datatable. I think I want to read each line using the xmltextreader using a while loop. Within the loop I want to write it out using the xmltextwriter. What is the code syntax I would use to read a line of data in the xml document and write it to the xml document?
