AttributeError: module 'lxml.etree' has no attribute 'xpath'. Did you mean: 'XPath'?

This error occurs when you try to access the 'xpath' attribute of the 'lxml.etree' module, but it does not exist. Instead, it suggests that you may have meant to use 'XPath' (capitalized) instead.

To resolve this error, change the code to use 'XPath' instead of 'xpath'. For example, instead of:

result = lxml.etree.xpath("//book")

Use:

result = lxml.etree.XPath("//book")

This should resolve the error and allow you to use the 'XPath' function from the 'lxml.etree' module.
