How to get path of an element in lxml?

Question

Hello, 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.

Answer 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]

Answer 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]']
