lxml.etree._Element' object has no attribute 'evaluate'

这个错误通常是因为在使用XPath表达式时,将其应用于一个`_Element`对象,而不是应用于`_ElementTree`对象。XPath表达式只能在整个XML文档上进行评估,而不是在单个元素上评估。因此,您需要将该元素作为整个XML文档进行处理。
您可以将该元素作为根元素创建一个`_ElementTree`对象,然后使用`xpath()`方法来评估XPath表达式。例如:
```
from lxml import etree
root = etree.fromstring('<bookstore><book><title>Harry Potter</title></book></bookstore>')
element = root.xpath('/bookstore/book/title')[0]
```
在这个例子中,我们使用`fromstring()`方法创建一个XML根元素。然后,我们使用XPath表达式`/bookstore/book/title`选择`title`元素。由于`xpath()`方法返回一个列表,我们使用`[0]`来获取第一个匹配项,也就是`title`元素本身。
希望这可以帮助您解决问题!

'lxml.etree._Element' object has no attribute getpath
The error message 'lxml.etree._Element' object has no attribute 'getpath' indicates that you are trying to call the getpath() method on an object of type '_Element' from the 'lxml.etree' module, but that method does not exist for that object.
To fix this error, you need to check the documentation for the specific version of lxml that you are using to see what methods are available for the '_Element' class. It's possible that the method has been deprecated or removed in that version, or that you are using the wrong method name or syntax.
Alternatively, you can try using a different method to achieve the same functionality or look for a workaround. For example, you might try using the 'xpath' method to select elements or the 'tag' attribute to get the tag name of an element.
