Element has no ancestor with line number.

I'd like to print an attribute, but I'm getting an error:

$ astpath '//Name/@id'
Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/astpath/search.py", line 44, in find_in_ast
    linenos = query(
  File "/usr/local/lib/python3.9/site-packages/astpath/search.py", line 12, in lxml_query
    return element.xpath(expression)
AttributeError: 'lxml.etree._ElementUnicodeResult' object has no attribute 'xpath'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/bin/astpath", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.9/site-packages/astpath/cli.py", line 37, in main

    file_matches = find_in_ast(
  File "/usr/local/lib/python3.9/site-packages/astpath/search.py", line 49, in find_in_ast
    raise AttributeError(
AttributeError: Element has no ancestor with line number.

Maybe if it's an ElementUnicodeResult we should just return instead of recursing into element.expath(expression)? Thanks for your work on this project!
