    I am trying to extract text from PDF file in PDFNetSDK by PDFTron. But when the execution comes to dumpAlltext() there is no element type e_text. When I am debuggin the code i can see element type is e_path..I think e_path is having the all the text in it. How can I extract the text from e_path??..Please help.
    Code:
    if sys.version_info.major < 3:
        from PDFNetPython2 import *
    else:
        from PDFNetPython3 import *
    
    def printStyle (style):
        print(" style=\"font-family:" + style.GetFontName() + "; font-size:"
              + str(style.GetFontSize()) + "; sans-serif: " + str(style.IsSerif())
              + "; color:" + str(style.GetColor())+ "\"")
    
    def dumpAllText (reader):
        element = reader.Next()
        while element != None:
            type = element.GetType()
            if type == Element.e_text_begin:
                print("Text Block Begin")
            elif type == Element.e_text_end:
                print("Text Block End")
            elif type == Element.e_text:
                bbox = element.GetBBox()
                print("BBox: " + str(bbox.GetX1()) + ", " + str(bbox.GetY1()) + ", "
                      + str(bbox.GetX2()) + ", " + str(bbox.GetY2()))
                print(element.GetTextString())
            elif type == Element.e_text_new_line:
                print("New Line")
            elif type == Element.e_form:
                reader.FormBegin()
                dumpAllText(reader)
                reader.End()
            elif type == Element.e_group_begin:
                print("Group begins")
            elif type == Element.e_group_end:
                print("Group ends")
            elif type == Element.e_path:
                bbox = element.GetBBox()
                print("BBox: " + str(bbox.GetX1()) + ", " + str(bbox.GetY1()) + ", "
                      + str(bbox.GetX2()) + ", " + str(bbox.GetY2()))
                print(element.GetTextData())
            element = reader.Next()
    
    def main():
        PDFNet.Initialize()
    
        # Relative path to the folder containing test files.
        input_path =  "test.pdf"
        example5_low_level = True
    
            if example5_low_level:
            doc = PDFDoc(input_path)
            doc.InitSecurityHandler()
    
            # Example 1. Extract all text content from the document
    
            reader = ElementReader()
            itr = doc.GetPageIterator()
            while itr.HasNext():
                reader.Begin(itr.Current())
                dumpAllText(reader)
                reader.End()
                itr.Next()
    
    if __name__ == '__main__':
        main()
