Hi people,

Currently I have a WSS site hosted on Microsoft Online
and am looking to create a button on the site which will export custom list items (if the invoiced column is set to no) so they can be either put into another site using either the PUT or POST methods, then edit the list item Invoiced column and change it to yes, however there needs to be some field modifications done to the xml before it is posted or put to the site, im a newbie to development and some pointers would be much appreciated. have worked out the Oauth to get it authenticated with the website where the data needs to be put and the website has a developer center and api endpoints we can use im just at a bit of a loss as to how to get the info out of sharepoint and into this site.

any help would be much appreciated
