将<suds.sax.text.text>对象转换为字符串？

Question

我的数据框中有一个类型为suds.sax.text.text的列，我想将其转换为字符串。除了这个site，我找不到太多关于如何做这件事的信息。使用pandas.DataFrame.astype不起作用。我相信有一个简单的方法可以做到这一点。这些文件简直让我摸不着头脑。我正在使用一个web服务来使用它的一些函数来返回气象站上的一些元数据。此元数据作为suds对象返回。指向web服务的链接是here.

    while 1:

            a_result = a_func(**kwargs)
            break

        except Exception as e:
            ntries += 1

            if ntries == ntries_max:

                       (str(a_func.method.name), str(e), sleep_sec)))
