Error: xml.etree.ElementTree.ParseError: not well-formed (invalid token): line 1, column 1



  • Hey guys,

    i wrote a little application with pyqt5 and it worked fine. But today suddenly i can't run the application. I get the following error:

    Traceback (most recent call last):
      File "C:/Users/hrezaie/Desktop/Hamid Rezaie/GuiApp/GuiApp/app.py", line 768, in <module>
        w = Fenster()

        self._root = parser._parse_whole(source)
    xml.etree.ElementTree.ParseError: not well-formed (invalid token): line 1, column 1
    
    Process finished with exit code 1
    
    

    I tryed to solve it but i can't. Has anybody an idea how i can solve it ?

    @elias_hh Are you parsing a XML document in your app? Is this document still valid XML?



  • @jsulm Hey, no i dont use any XML document. I think the problem is my .ui file. Because if i want to open it with qt designer i get suddenly a error message to.

    Hi
    What was it ? Just so others might also be able to fix it.



  • @mrjj hey, unfortunately I didn't solve it in a nice way, but simply recreated the gui again. Afterwards it worked again.
