Generate XPath expressions of elements inside selenium element

Given a selenium element, generate XPath expressions of all button elements descendants of that element.
In other words: programmatically generate xpath expressions to be used by selenium.

    answer = driver.find_element("xpath", tree_start).get_attribute("outerHTML")
    
    # parse answer html with lxml.html
    doc = html.fromstring(answer)
    # build all XPath expressions for button elements with xml2xpath
    tree, nsmap, xmap = xml2xpath.parse(file=None,itree=doc.getroottree(), xpath_base=f"{tree_start}//button")
    #xml2xpath.print_xpaths(xmap, mode="all")
    
    for x in xmap.values():
        button = tree.xpath(x[0])[0]
        print(f"Label: '{button.text.strip()}', xpath: {x[0]}")
        # click it?

finally:
    driver.quit()
