装饰lxml.etree._Element方法
[英]decorate lxml.etree._Element methods
问题描述
I tried to decorate/override/patch the 'get' , 'text' , and 'findtext' methods of lxml.etree._Element , but it seems like it's impossible to achieve, as all the attributes are read-only, probably because it's not written in python. 
我试图装饰/覆盖/修补“得”，“ 文本”和“FINDTEXT” lxml.etree._Element的方法，但现在看来似乎是不可能实现的，因为所有的属性是只读的，可能是因为它是不是用python编写的。 Is there a way to decorate those methods? 有没有办法装饰这些方法？ Thanks for any suggestions.. 感谢您的任何建议。

After reading the comments, I listened to the suggestion to use unicode everywhere, and encode to string just when outputting the data. 阅读注释后，我听了有关在各处使用unicode的建议，并在输出数据时将其编码为字符串。 Thanks for that, however I was curious after all to accomplish the task I wanted anyway, so here's what I've came up with, an lxml._Element class wrapper: 为此，尽管如此，我还是很好奇，无论如何我还是想完成我想要的任务，所以这就是我想出的一个lxml._Element类包装器：

Maybe someone else will find it useful for something after all, as I did not find other orthodox solutions. 毕竟，有人可能会发现它对某些事情有用，因为我没有找到其他正统的解决方案。
