You might have to be a bit more specific. There are many places called Langendorf, at least 9 in present day Germany, as well as a town in Switzerland, and a place in Austria. In addition to those, there are many places in Poland, Czechia, Slovakia, Roumania, Russia etc where the German name was Langendorf. See: https://de.wikipedia.org/wiki/Langendorf
Using Menk's "Dictionary of German-Jewish Surnames" https://www.avotaynu.com/books/Menk.htm
I conclude that you are probably referring to Bodzanow in Poland https://en.wikipedia.org/wiki/Bodzan%C3%B3w,_Opole_Voivodeship
but I could be wrong. That Langendorf is in Upper Silesia. I have ancestors from that general area, and I haven't yet seen their records of citzenship/name adoption. I think the official publication was in the "Amts-Blatt der Koniglichen Breslauchen Regierung" See pages 106 and 107 of Menk.
The ancestry collection you refer to applies to West Prussia. This refers to an area in Northern Poland surrounding Danzig/Gdansk and a long way from Upper Silesia. See: https://en.wikipedia.org/wiki/West_Prussia
I hope this helps, if only a little
