Solution 1
Use getpath
from ElementTree objects.
from lxml import etree
root = etree.fromstring('''
<foo><bar>Data</bar><bar><baz>data</baz>
<baz>data</baz></bar></foo>
''')
tree = etree.ElementTree(root)
for e in root.iter():
print(tree.getpath(e))
Prints
/foo
/foo/bar[1]
/foo/bar[2]
/foo/bar[2]/baz[1]
/foo/bar[2]/baz[2]
Solution 2
See the Xpath and XSLT with lxml from the lxml documentation This gives the path of the element containg the text
An example would be
import cStringIO
from lxml import etree
f = cStringIO.StringIO('<foo><bar><x1>hello</x1><x1>world</x1></bar></foo>')
tree = lxml.etree.parse(f)
find_text = etree.XPath("//text()")
# and print out the required data
print [tree.getpath( text.getparent()) for text in find_text(tree)]
# answer I get is
>>> ['/foo/bar/x1[1]', '/foo/bar/x1[2]']
Solution 3
If all you have in your section of code is the element and you want the element's xpath do then element.getroottree().getpath(element)
will do the job.
from lxml import etree
xml = '''
<test>
<a/>
<b>
<i/>
<ii/>
</b>
</test>
'''
tree = etree.fromstring(xml)
for element in tree.iter():
print element.getroottree().getpath(element)
Solution 4
root = etree.parse(open('tmp.txt'))
for e in root.iter():
print root.getpath(e)

I'm searching in a HTML document using XPath from lxml in python. How can I get the path to a certain element? Here's the example from ruby nokogiri:
page.xpath('//text()').each do |textnode| path = textnode.path puts path end
print for example '/html/body/div/div[1]/div[1]/p/text()[1]' and this is the string I want to get in python.

Jabba almost 13 yearsI think it should be
for e in tree.iter():
, i.e. tree.iter. -
nosklo over 12 years@Jabba And why do you think that? Have you tried the code I provided the way it is? It seems to work, no? Do you have a reason to think otherwise?

Kevin Vasko about 7 yearsIt might have not existed when you wrote this originally and not that it actually matters, but you can also do
tree = root.getroottree()
to get an ElementTree object. -
johann_ka over 2 yearsJust for the sake of completion, when I use
https://requests-html.kennethreitz.org/
to pull a webpage, I do the following:webpage = session.get('URL HERE')
thenroot = etree.HTML(webpage.text)
thentree = etree.ElementTree(root)
and then simply the for loop as stated in the answer.
