The following is an example of some sample script output using XSLT (and some quick styling). Obviously, it'll be looking different and fully tweaked by the end result, but for the time being, structuring and outputting the script in general is no problem.

Script

Palantine is not a Hubert Humphrey-type professional bullshitter, and Travis' intense reply stops him dead in his tracks. He is forced to fall back on a stock answer but tries to give it some meaning.
pal: PALANTINE Travis, what single thing would you want the next President of this country to do most?
trav: TRAVIS I don't know, sir. I don't follow political issues much.
pal: PALANTINE There must be something...
trav: TRAVIS (thinks) Well, he should clean up this city here. It's full of filth and scum. Scum and filth. It's like an open sewer. I can hardly take it. Some days I go out and smell it then I get headaches that just stay and never go away. We need a President that would clean up this whole mess. Flush it out. (thinks)
pal: PALANTINE (after a pause) I know what you mean, Travis, and it's not going to be easy. We're going to have to make some radical changes. (after a pause)
trav: TRAVIS (turning the wheel) Damn straight. (turning the wheel)
EXT. BARCLAY HOTEL
TRAVIS' taxi pulls up in front of the Barclay Hotel. PALANTINE and AIDE get out of the cab. SECOND AIDE stays in back seat a moment to pay TRAVIS. PALANTINE looks in front window of cab momentarily and nods goodbye to TRAVIS.
Travis' taxi departs. PALANTINE and AIDES walk up carpet to the St. Regis. CAMERA CLOSES IN on PALANTINE as he stops, turns back and watches Travis' departing taxi. PALANTINE turns back and ascends the hotel steps with his AIDES.
pal: PALANTINE Nice talking to you, Travis.
trav: TRAVIS (calling back) Thank you, sir. You're a good man, sir. (calling back)
ON THE SIDEWALK
EXT. MANHATTAN STREET - EARLY MORNING TRAVIS, dressed to the teeth, walks brightly down the sidewalk. His face is frehsly shaved, his hair combed, his tie straightened. He pauses in a store window to check his appearance. Under his arm he carries the gift-wrapped Kristofferson record album. OUTSIDE PALANTINE HEADQUARTERS BETSY, smartly dressed, waves goodbye to another CAMPAIGN WORKER and walks out the door to greet him. A SHORT WHILE LATER, TRAVIS and BETSY are walking down Broadway toward Times Square. BETSY does not let their bodies touch as they walk although TRAVIS contemplates edging closer to her. Betsy has opened the package and is admiring the record - or, rather, Travis' sentiment behind giving it. Travis looks around himself with pride: This is a moment in his life - one of the few.
Betsy notices that the seal on the record has not been broken.
