can we use XPath with BeautifulSoup?

Question

I am using BeautifulSoup to scrape an URL and I had the following code, to find the td tag whose class is 'empformbody':

import urllib
import urllib2
from BeautifulSoup import BeautifulSoup

url =  "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
req = urllib2.Request(url)
response = urllib2.urlopen(req)
the_page = response.read()
soup = BeautifulSoup(the_page)

soup.findAll('td',attrs={'class':'empformbody'})

Now in the above code we can use findAll to get tags and information related to them, but I want to use XPath. Is it possible to use XPath with BeautifulSoup? If possible, please provide me example code.

Solution 1

Nope, BeautifulSoup, by itself, does not support XPath expressions.

An alternative library, lxml, does support XPath 1.0. It has a BeautifulSoup compatible mode where it'll try and parse broken HTML the way Soup does. However, the default lxml HTML parser does just as good a job of parsing broken HTML, and I believe is faster.

Once you've parsed your document into an lxml tree, you can use the .xpath() method to search for elements.

try:
    # Python 2
    from urllib2 import urlopen
except ImportError:
    from urllib.request import urlopen
from lxml import etree

url =  "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = urlopen(url)
htmlparser = etree.HTMLParser()
tree = etree.parse(response, htmlparser)
tree.xpath(xpathselector)

There is also a dedicated lxml.html() module with additional functionality.

Note that in the above example I passed the response object directly to lxml, as having the parser read directly from the stream is more efficient than reading the response into a large string first. To do the same with the requests library, you want to set stream=True and pass in the response.raw object after enabling transparent transport decompression:

import lxml.html
import requests

url =  "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = requests.get(url, stream=True)
response.raw.decode_content = True
tree = lxml.html.parse(response.raw)

Of possible interest to you is the CSS Selector support; the CSSSelector class translates CSS statements into XPath expressions, making your search for td.empformbody that much easier:

from lxml.cssselect import CSSSelector

td_empformbody = CSSSelector('td.empformbody')
for elem in td_empformbody(tree):
    # Do something with these table cells.

Coming full circle: BeautifulSoup itself does have very complete CSS selector support:

for cell in soup.select('table#foobar td.empformbody'):
    # Do something with these table cells.

Solution 2

I can confirm that there is no XPath support within Beautiful Soup.

Solution 3

As others have said, BeautifulSoup doesn't have xpath support. There are probably a number of ways to get something from an xpath, including using Selenium. However, here's a solution that works in either Python 2 or 3:

from lxml import html
import requests

page = requests.get('http://econpy.pythonanywhere.com/ex/001.html')
tree = html.fromstring(page.content)
#This will create a list of buyers:
buyers = tree.xpath('//div[@title="buyer-name"]/text()')
#This will create a list of prices
prices = tree.xpath('//span[@class="item-price"]/text()')

print('Buyers: ', buyers)
print('Prices: ', prices)

I used this as a reference.

Solution 4

BeautifulSoup has a function named findNext from current element directed childern,so:

father.findNext('div',{'class':'class_value'}).findNext('div',{'id':'id_value'}).findAll('a') 

Above code can imitate the following xpath:

div[class=class_value]/div[id=id_value]

Solution 5

from lxml import etree
from bs4 import BeautifulSoup
soup = BeautifulSoup(open('path of your localfile.html'),'html.parser')
dom = etree.HTML(str(soup))
print dom.xpath('//*[@id="BGINP01_S1"]/section/div/font/text()')

Above used the combination of Soup object with lxml and one can extract the value using xpath

yes actually until now i used scrapy which uses xpath to fetch the data inside tags.Its very handy and easy to fetch data, but i got a need to do the same with beautifulsoup so looking forward in to it.

[Shiva Krishna Bavandla]

Thanks very much Pieters, i got two informations from ur code,1. A clarification that we can't use xpath with BS 2.A nice example on how using lxml. Can we see it on a particular documentation that "we can't implement xpath using BS in written form", because we should show some proof to someone those who ask for clarification right?

[Martijn Pieters]

It's hard to prove a negative; the BeautifulSoup 4 documentation has a search function and there are no hits for 'xpath'.

It would be very nice to be able to use XPATH within BeautifulSoup

[static_rtti]

So what is the alternative?

[wordsforthewise]

One warning: I've noticed if there is something outside the root (like a \n outside the outer <html> tags), then referencing xpaths by the root will not work, you have to use relative xpaths. lxml.de/xpathxslt.html

[robertspierre]

I believe this only finds the child elements. XPath is another thing?

[Martijn Pieters]

Martijn's code no longer works properly (it is 4+ years old by now...), the etree.parse() line prints to the console and doesn't assign the value to the tree variable. That's quite a claim. I certainly can't reproduce that, and it would not make any sense. Are you sure you are using Python 2 to test my code with, or have translated the urllib2 library use to Python 3 urllib.request?

[wordsforthewise]

Yeah, that may be the case that I used Python3 when writing that and it didn't work as expected. Just tested and yours works with Python2, but Python3 is much preferred as 2 is being sunset (no longer officially supported) in 2020.

[Martijn Pieters]

absolutely agree, but the question here uses Python 2.

[AMC]

select() is for CSS selectors, it's not XPath at all. as you see, this does not support sub-tag While I'm not sure if that was true at the time, it certainly isn't now.

[Zvi]

I tried running your code above but got an error "name 'xpathselector' is not defined"

[Martijn Pieters]

@Zvi the code doesn’t define an Xpath selector; I meant it to be read as “use your own XPath expression here”.

@leonard-richardson It's 2021, are you still confirming that BeautifulSoup STILL does not have xpath support?
