Are you saying that Palestinians never had aims for self determination during the time of the Ottoman Empire or British rule?
Essentially, yes.
The Arabs in the area didn't see themselves as a seperate nation of "Palestinians" until the 1940s or so at the earliest; before that they saw themselves as Egyptians, Syrians, or just as members of tribe X. There was Arab nationalism -- e.g., against Ottoman (Turkish) or British rule -- but not Palestinian one.
If we go further back to the 19th century, this is not surprising: most Arabs who were in Palestine in, say, 1920 were mostly those (or the descendents of those) who came to Palestine after the Jewish emigration started, attracted by better conditions than elsewhere in the levant. It is not surprising they didn't see themselves as part of a nationality at the time.
The father of Palestinian nationalism (again, as opposed to Arab nationalism is general) was the war criminal Haj Amin Al-Husseini, from the 1930s and 40s, who collaborated with Hitler, and who saw Palestinian nationalism more as an excuse to genocide the Jews than anything else. To this day, the Palestinian Constitution of the PLO (and that of Hamas as well) has as its #1 objective the destruction of the Jewish state: the only nation in the world whose constitution calls for the destruction of another nation.
But then again, looking at the founder of Palestinian nationalism, who begged Hitler to kill as many Jews as possible lest they emigrate to Palestine and declared his goal is for the Arabs to deal with the Jews in Palestine using the same methods the Nazis used in Europe, is this really surprising? After all, one wouldn't expect a constitution written by, say, Charley Manson to be all sweetness and light.
That aside, then, no: one can speak of Palestinian nationalism during the (later) British mandate, but certainly not during the earlier part of that rule, let alone Ottoman times.
Sorry to ruin your fantasy du jour.
