AttributeError: 'lxml.etree._Element' object has no attribute 'tostring'

AttributeError: 'lxml.etree._Element' object has no attribute 'tostring'是因为lxml库中的Element对象没有tostring属性。你可以使用lxml库中的etree.tostring()方法来将Element对象转换为字符串。例如,你可以使用以下代码来解决这个错误:
```python
from lxml import etree
# 假设element是你的lxml.etree._Element对象
element_str = etree.tostring(element).decode()
```

AttributeError: 'lxml.etree._Element' object has no attribute 'path'
`AttributeError: 'lxml.etree._Element' object has no attribute 'path'` 是一个Python错误,当你尝试在一个 `lxml.etree._Element` 对象上调用名为 `path` 的属性时,会抛出这个异常。`lxml` 是一个用于处理XML和HTML文档的强大库,在这里,它返回的是元素树结构的一部分,而不是像字典那样直接拥有路径属性。
通常,`path` 属性用于某些特定的对象或API,比如XPath表达式在BeautifulSoup这样的库中才有。如果你试图在`lxml.etree.Element`上找 `path`,可能是因为你误用了API,或者文档已经被解析但你想访问原始XML中的某个属性或路径信息,这时候你需要查阅lxml的官方文档或者检查你的代码,确保你正确地定位到了需要的节点并获取其路径。
AttributeError: 'lxml.etree._Element' object has no attribute 'XPATH'
AttributeError: 'lxml.etree._Element' object has no attribute 'XPATH'错误是由于你在使用lxml库的etree模块时,错误地使用了XPATH属性。正确的写法应该是使用xpath()方法而不是XPATH属性。在你的代码中,将XPATH改为小写的xpath,并将其作为方法调用即可。
例如,将代码修改为:
```
positionName = html.xpath("//div[@class='position-head']/div/div<span class="em">1</span><span class="em">2</span><span class="em">3</span>
