Any tools like xed or xml tools on Linux that could achieve the above.

*"I would like to change the above to below format"* - You most certainly do not want that. Would you care to explain why you think that's necessary? — Tomalak, Jan 27 '14 at 09:55
I have to generate a pkcs10 request and provide the request in an xml format because the pki server that i am using accpets the request be put in an xml file — Niranjan M.R, Jan 27 '14 at 10:03
Any specific reason why you feel that changing could have issue ? — Niranjan M.R, Jan 27 '14 at 10:03
Yes. First you seem to be using text tools to generate XML. This is wrong, you really should use an XML API. They are abundant in any programming environment, there is no excuse for using `sed`. Second, XML is perfectly capable of retaining line breaks. You absolutely don't need to do anything special, adding ` ` to your text is plain wrong. Just use - for example - Python with `etree` to build the XML you need, store the key string in it. — Tomalak, Jan 27 '14 at 10:09

You could use sed:

sed ':a;N;$!ba;s/\n/\&#xD;&/g' filename

For saving the changes to the input file in-place, add the -i option.

For your input, this would produce:
