361485 Drop down xml

I need a script that can alter a xml document with some extra lines of xml code using a visual dropdown selection tool. I have a productfeed xml document. The xml document provides images of clothing. To each clothing (feed) I want to assign a color. This color has to be added to each feed as a xml line code. The colors that I want to choose from are fixed. I have the following in mind: A script that reads a xml document. The productfeed will show the image per feed. The programming: Next to the feed displays a dropdown single selection menu with an option to select a color. The colors are: white, silver, grey, black, brown, gold, yellow, green, blue, purple, pink, red and orange. Once selected a color for each feed it is possible to save the selections. Onces saved, it adds the following code to each feed respecting the selected color: If 'white' is the case: Conditions that have to be met: - the scripts that reads the xml document displays 50 feeds per page; - every page displays a pagination with the numbers of the pages to go to; - every page has a save button at the end; - if color is selected and saved (line of code is in place) it will still display the selected color in frontend (in the dropdown as selected)even after refresh of the page; - if color is selected and saved and page is refreshed than the color is also mentioned below the other data; - colors can be changed later on (so the line of xml code can rewrite itself); - it doesn't have to be designful, just the script. The man/firm to win the job will receive an example productfeed xml document to work with. I added some extra info to this project for additional specification for the script. If you feel you are able to live up to it, send me a PM and I will reply! I want to make a decision end of this week, so be quickly! All that is red is added, see attachment.
