While writing back xml document to a file it removes all comments

[Ajay-MS]

Hello Team,

I have an sample.xml file which contains comments also. Using xmldoc when i first convert it into a DOM structure and again write back dom to file it writes without comment. I think all comments are being committed by xmldoc when creating a DOM structure itself.

Hi Ajay - The design goal of xmldoc was to be a "reader" of XML, and not a complete "XML Document Editor". Although it can "print out" XML documents, it makes no guarantees of round-trip accuracy, as you've experienced with comment nodes.

I do recognize that a lot of people wish for this functionality though, so if you would like to submit a PR that adds this functionality, in a way that doesn't add much complexity or new lines of code to the module, then I would be happy to review it!
