I have a big HTML file from which I need to parse some data using Regular expression. The first is the name of restaurant. Hotel names are in this format:

There are altogether 40 hotels. I think there's two spaces after the . in number. I need to list all the hotels from 1 to 40. I have tried using:
re.findall("[./0-9]", string_Name)
It outputs the number. I want to get the number and all the hotel names. How can I do that?
The answer by Blender gives the rating and the restaurant list. That's fine but I want rating and the restaurant name in a different variable.
Parse the HTML:
import re
from bs4 import BeautifulSoup
html = '''
<a href="https://courses.ischool.berkeley.edu/biz/capannina-san-francisco" id="bizTitleLink0">1. Capannina
</a>
<a href="https://courses.ischool.berkeley.edu/biz/ristorante-parma-san-francisco" id="bizTitleLink4">5. Ristorante Parma
</a>
'''
soup = BeautifulSoup(html)
for link in soup.find_all('a', text=re.compile(r'^\d')):
print link.get_text()
And the output:
1. Capannina
5. Ristorante Parma
You shouldn't run regexes on html directly (preferring to use an HTML parser first), but try this regex:
(\d+)\.\s+([^<]+)
one or more digits
a dot
one or more whitespace characters
one or more non < letters
The presence of the brackets () creates a capture group. The contents of the capture group 1 will be the number. The contents of the capture group 2 will be the name.

trying to get specific text that is in a span class from a web page. I can get the first instance, but not sure how to iterate to get the one i need.
<div class="pricing-base__plan-pricing">
<div class="pricing-base__plan-price pricing-base__plan-price--annual">
<sup class="pricing-base__price-symbol">$</sup>
<span class="pricing-base__price-value">14</span></div>
<div class="pricing-base__plan-price pricing-base__plan-price--monthly">
<sup class="pricing-base__price-symbol">$</sup>
<span class="pricing-base__price-value">18</span>
</div>
<div class="pricing-base__term">
<div class="pricing-base__term-wrapper">
<div class="pricing-base__date">mo*</div>
</div>
I need to get the "18" in the line
18
that number changes quite often and that is what my code is looking to scrape.
You can use a class selector as shown to retrieve a list of all prices then index into that list to get annual and monthly
import requests
from bs4 import BeautifulSoup as bs
r = requests.get('https://www.gotomeeting.com/meeting/pricingc')
soup = bs(r.content, 'lxml')
prices = [item.text for item in soup.select('.pricing-base__price-value')]
monthly = prices[1]
annual = prices[0]
You could also add in parent classes:
monthly = soup.select_one('.pricing-base__plan-price--monthly .pricing-base__price-value').text
annual = soup.select_one('.pricing-base__plan-price--annual .pricing-base__price-value').text
Example:
I have the follow html structure:
<div id="mod_imoveis_result">
<a class="mod_res" href="#">
<div id="g-img-imo">
<div class="img_p_results">
<img src="/img/image.jpg">
</div>
</div>
</a>
</div>
This is a product result page, so is 7 blocks for page with that mod_imoveis_result id. I need get image src from all blocks. Each page have 7 blocks like above.
I try:
import scrapy
from scrapy.pipelines.images import ImagesPipeline
from scrapy.exceptions import DropItem
class QuotesSpider(scrapy.Spider):
name = "magichat"
start_urls = ['https://magictest/results']
def parse(self, response):
for bimb in response.xpath('//div[#id="mod_imoveis_result"]'):
yield {
'img_url': bimb.xpath('//div[#id="g-img-imo"]/div[#class="img_p_results"]/img/#src').extract_first(),
'text': bimb.css('#titulo_imovel::text').extract_first()
}
next_page = response.xpath('//a[contains(#class, "num_pages") and contains(#class, "pg_number_next")]/#href').extract_first()
if next_page is not None:
yield response.follow(next_page, self.parse)
I can't understand why text target is ok, but img_url get first result for all blocks for page. Example: each page have 7 blocks, so 7 texts and 7 img_urls, but, img_urls is the same for all other 6 blocks, and text is right, why?
If i change extract_first to extract i get others urls, but the result come in the same brackts. Example:
text: 1aaaa
img_url : a,b,c,d,e,f,g
but i need
text: 1aaaa
img_url: a
text: 2aaaa
img_url: b
What is wrong with that loop?
// selects the root node i.e. <div id="mod_imoveis_result"> of for node you're trying to get which is div[#id="g-img-imo"] so the two tage that were missed it the reason of NO DATA
**. **selects the current node which is mentioned in your xpath irrespective of how deep it is.
In your case xpath('./div[#id="g-img-imo"]/div[#class="img_p_results"]/img/#src') denotes selection from root node i.e. from arrow
<div id="mod_imoveis_result">
<a class="mod_res" href="#">
---> <div id="g-img-imo">
<div class="img_p_results">
<img src="/img/image.jpg">
</div>
</div>
</a>
</div>
I hope you i made it clear.
If all your classes have separate div names, in your case different class tag, then you can directly call image div and extract image URL.
//*[#class="img_p_results"]/img/#src
I basically want to scrape Litigation Paralegal under <h3 class="Sans-17px-black-85%-semibold"> and Olswang under <span class="pv-entity__secondary-title Sans-15px-black-55%">, but I can't see to get to it. Here's the HTML at code:
<div class="pv-entity__summary-info">
<h3 class="Sans-17px-black-85%-semibold">Litigation Paralegal</h3>
<h4>
<span class="visually-hidden">Company Name</span>
<span class="pv-entity__secondary-title Sans-15px-black-55%">Olswang</span>
</h4>
<div class="pv-entity__position-info detail-facet m0"><h4 class="pv-entity__date-range Sans-15px-black-55%">
<span class="visually-hidden">Dates Employed</span>
<span>Feb 2016 – Present</span>
</h4><h4 class="pv-entity__duration de Sans-15px-black-55% ml0">
<span class="visually-hidden">Employment Duration</span>
<span class="pv-entity__bullet-item">1 yr 2 mos</span>
</h4><h4 class="pv-entity__location detail-facet Sans-15px-black-55% inline-block">
<span class="visually-hidden">Location</span>
<span class="pv-entity__bullet-item">London, United Kingdom</span>
</h4></div>
</div>
And here is what I've been doing at the moment with selenium in my code:
if tree.xpath('//*[#class="pv-entity__summary-info"]'):
experience_title = tree.xpath('//*[#class="Sans-17px-black-85%-semibold"]/h3/text()')
print(experience_title)
experience_company = tree.xpath('//*[#class="pv-position-entity__secondary-title pv-entity__secondary-title Sans-15px-black-55%"]text()')
print(experience_company)
My output:
Experience title : []
[]
Your XPath expressions are incorrect:
//*[#class="Sans-17px-black-85%-semibold"]/h3/text() means text content of h3 which is child of element with class name attribute "Sans-17px-black-85%-semibold". Instead you need
//h3[#class="Sans-17px-black-85%-semibold"]/text()
which means text content of h3 element with class name attribute "Sans-17px-black-85%-semibold"
In //*[#class="pv-position-entity__secondary-title pv-entity__secondary-title Sans-15px-black-55%"]text() you forgot a slash before text() (you need /text(), not just text()). And also target span has no class name pv-position-entity__secondary-title. You need to use
//span[#class="pv-entity__secondary-title Sans-15px-black-55%"]/text()
You can get both of these easily with CSS selectors and I find them a lot easier to read and understand than XPath.
driver.find_element_by_css_selector("div.pv-entity__summary-info > h3").text
driver.find_element_by_css_selector("div.pv-entity__summary-info span.pv-entity__secondary-title").text
. indicates class name
> indicates child (one level below only)
indicates a descendant (any levels below)

I am using Scrapy and XPath to parse web-site in Russian language.
In this topic, alecxe suggested me how to construct the xpath expression to get the values. However, I don't understand how can I handle the case when the Param1_name is in Russian?
Here is the xpath expression:
//*[text()="Param1_name_in_russian"]/following-sibling::text()
Html snippet:
<div class="obj-params">
<div class="wrap">
<div class="obj-params-col" style="min-width:50%;">
<p>
<b>Param1_name_in_russian</b>" Param1_value"</p>
<p>
<strong>Param2_name_in_russian</strong>" Param2_value</p>
<p>
<strong>Param3_name_in_russian</strong>" Param3_value"</p>
</div>
</div>
<div class="wrap">
<div class="obj-params-col">
<p>
<b>Param4_name_in_russian</b>Param4_value</p>
<div class="inline-popup popup-hor left">
<b>Param5_name</b>
<a target="_blank" href="link">Param5_value</a></div></div>
EDITED based on comments
I assume I didn't specify properly the question since all suggested solutions didn't work for me i.e. when I tested the suggested XPath expressions in Scrapy console output was nothing. Thus, I provide more detailed information about web-site that I need to parse:
link to the web-site: link to real-estate web site
screenshot of what I need to parse:
Consider declaring your encoding at the beginning of the file as latin-1. See the documentation for a thorough explanation as to why.
I'll be using lxml instead of Scrapy below, but the logic is the same.
Code:
#!/usr/bin/env python
# -*- coding: latin-1 -*-
from lxml import html
markup = """div class="obj-params">
<div class="wrap">
<div class="obj-params-col" style="min-width:50%;">
<p>
<b>Некий текст</b>" Param1_value"</p>
<p>
<strong>Param2_name_in_russian</strong>" Param2_value</p>
<p>
<strong>Param3_name_in_russian</strong>" Param3_value"</p>
</div>
</div>
<div class="wrap">
<div class="obj-params-col">
<p>
<b>Param4_name_in_russian</b>Param4_value</p>
<div class="inline-popup popup-hor left">
<b>Param5_name</b>
<a target="_blank" href="link">Param5_value</a></div></div>"""
tree = html.fromstring(markup)
pone_val = tree.xpath(u"//*[text()='Некий текст']/following-sibling::text()")
print pone_val
Result:
['" Param1_value"']
[Finished in 0.5s]
Note that since this is a unicode string, the u at the beginning of the Xpath is necessary, same as #warwaruk's comment in your question.
Let us know if this helps.
EDIT:
Based on the site's markup, there's actually a better way to get the values. Again, using lxml and not Scrapy since the difference between the two here is just .extract() anyway. Basically, check my XPath for the name, room, square, and floor.
import requests as rq
from lxml import html
url = "http://www.lun.ua/%D0%BF%D1%80%D0%BE%D0%B4%D0%B0%D0%B6%D0%B0-%D0%BA%D0%B2%D0%B0%D1%80%D1%82%D0%B8%D1%80-%D0%BA%D0%B8%D0%B5%D0%B2"
r = rq.get(url)
tree = html.fromstring(r.text)
divs = tree.xpath("//div[#class='obj-left']")
for div in divs:
name = div.xpath("./h3/span/a/text()")[0]
details = div.xpath(".//div[#class='obj-params-col'][1]")[0]
room = details.xpath("./p[1]/text()[last()]")[0]
square = details.xpath("./p[2]/text()[last()]")[0]
floor = details.xpath("./p[3]/text()[last()]")[0]
print name.encode("utf-8")
print room.encode("utf-8")
print square.encode("utf-8")
print floor.encode("utf-8")
This doesn't print them out all well on my end (getting some [Decode error - output not utf-8]). However, I believe that encoding aside, using this approach is much better scraping practice overall.
Let us know what you think.
I'm trying to scrape sites like this one on the BBC website to grab the relevant parts of the programme listing, and I've just started using BeautifulSoup to do this.
The parts of interest start with sections like:
<li about="/programmes/p013zzsl#segment" class="segment track" id="segmentevent-p013zzsm" typeof="po:MusicSegment">
<li about="/programmes/p014003v#segment" class="segment speech alt" id="segmentevent_p014003w" typeof="po:SpeechSegment">
What I've done so far is opened the HTML as soup and then used soup.findAll(typeof=['po:MusicSegment', 'po:SpeechSegment']) to give a ResultSet of the parts I'm interested in the order in which they appear.
What I then want to do is check whether a section refers to po:MusicSegment or po:SpeechSegment in HTML that looks like:
<li about="/programmes/p01400m9#segment" class="segment track" id="segmentevent-p01400mb" typeof="po:MusicSegment"> <span class="artist-image"> <span class="depiction" rel="foaf:depiction"><img alt="" height="63" src="http://static.bbci.co.uk/programmes/2.54.3/img/thumbnail/artists_default.jpg" width="112"/></span> </span> <script type="text/javascript"> window.programme_data.tracklist.push({ segment_event_pid : "p01400mb", segment_pid : "p01400m9", playlist : "http://www.bbc.co.uk/programmes/p01400m9.emp" }); </script> <h3> <span rel="mo:performer"> <span class="artist no-image" property="foaf:name" typeof="mo:MusicArtist">Mala</span> </span> <span class="title" property="dc:title">Calle F</span> </h3></li>
I want to access the typeof attribute associated with <li>, but if this chunk of HTML (as a BS4 tag) is called section and I enter section.li, it returns None.
Note that if I do section.img instead, I get something back:
<img alt="" height="63" src="http://static.bbci.co.uk/programmes/2.54.3/img/thumbnail/artists_default.jpg" width="112"/>
and I could then do, e.g. section.img['height'] to get back u'63'
What I want is something analogous for the section.li part, so section.li['typeof'] to give me po:MusicSegment or po:SpeechSegment
Of course, I could simply convert each result to text and then do a simple string search, but searching by attribute seems more elegant.
I'd iterate over the list returned by findAll:
soup = BeautifulSoup('<li about="/programmes/p013zzsl#segment" class="segment track" id="segmentevent-p013zzsm" typeof="po:MusicSegment"><li about="/programmes/p014003v#segment" class="segment speech alt" id="segmentevent_p014003w" typeof="po:SpeechSegment">')
for elem in soup.findAll(typeof=['po:MusicSegment', 'po:SpeechSegment']):
print elem['typeof']
returns
po:MusicSegment
po:SpeechSegment
and then conditionally perform your other tasks:
if elem['typeof'] == 'po:MusicSegment'
do.something()
elif elem['typeof'] == 'po:SpeechSegment':
do.something_else()
