hi: in xpath_parser.py file

def p_path_expr_3(p):
    'PathExpr : FilterExpr SLASH RelativeLocationPath'
    p[0] = [p[1]]
    p[0].extend(p[3])
def p_path_expr_4(p):
    'PathExpr : FilterExpr DOUBLESLASH RelativeLocationPath'
    p[0] = [p[1]]
    p[0].append(_expand_double_slash())
    p[0].extend(p[3])

why not 

def p_path_expr_3(p):
    'PathExpr : FilterExpr SLASH RelativeLocationPath'
    p[0] = [p[1]]
    p[0].extend(p[3])
    p[0] = ('path_expr',p[0])
def p_path_expr_4(p):
    'PathExpr : FilterExpr DOUBLESLASH RelativeLocationPath'
    p[0] = [p[1]]
    p[0].append(_expand_double_slash())
    p[0].extend(p[3])
    p[0] = ('path_expr',p[0])
