将Python ElementTree转换为string

我读过文档，我知道它有关于ElementTree.tostring(e)但每当我打电话，我得到以下错误信息：

 AttributeError: 'Element' object has no attribute 'getroot' 

有没有其他的方法来将ElementTree对象转换为XMLstring？

追溯：

 Traceback (most recent call last): File "Development/Python/REObjectSort/REObjectResolver.py", line 145, in <module> cm = integrateDataWithCsv(cm, csvm) File "Development/Python/REObjectSort/REObjectResolver.py", line 137, in integrateDataWithCsv xmlstr = ElementTree.tostring(et.getroot(),encoding='utf8',method='xml') AttributeError: 'Element' object has no attribute 'getroot' 

Answer 1

Element对象没有.getroot()方法。 放下那个调用，并且tostring()调用起作用：

 xmlstr = ElementTree.tostring(et, encoding='utf8', method='xml')
