hi is There any way to get all The parent elements of a Tag using requests-HTML?
for example:
<!DOCTYPE html>
<html lang="en">
<body id="two">
<h1 class="text-primary">hello there</h1>
<p>one two tree<b>four</b>five</p>
</body>
</html>
I want to get all parent of b tag: [html, body, p]
or for the h1 tag get this result: [html, body]
With the excellent lxml :
from lxml import etree
html = """<!DOCTYPE html>
<html lang="en">
<body id="two">
<h1 class="text-primary">hello there</h1>
<p>one two tree<b>four</b>five</p>
</body>
</html> """
tree = etree.HTML(html)
# We search the first <b> element
b_elt = tree.xpath('//b')[0]
print(b_elt.text)
# -> "four"
# Walking around ancestors of this <b> element
ancestors_tags = [elt.tag for elt in b_elt.iterancestors()]
print(ancestors_tags)
# -> [p, body, html]
