No, Python's BeautifulSoup doesn't support XPath selectors despite supporting lxml backend which can perform XPath queries.
To use XPath selectors either lxml or parsel packages must be used.
lxml which makes xpath selections very easy:from parsel import Selector
selector = Selector(text='<div class="price">22.85</div>')
print(selector.xpath("//div[@class='price']/text()").get())
"22.85"
Alternatively, lxml can be used directly:
from lxml import html
tree = html.fromstring('<div class="price">22.85</div>')
print(tree.xpath("//div[@class='price']/text()"))
"22.85"
