python - Extracting url from style: background-url: with beautifulsoup and without regex? -

-

मेरे पास: 

  
 div class = "image" style = "background- छवि: url ('/ अपलोड / चित्र / खिलाड़ियों / 16113-1399107741.jpeg'); "

मुझे यूआरएल प्राप्त करना है, हालांकि मैं कैसे नहीं कर सकता regex के उपयोग के बिना ऐसा करना क्या यह संभव है?

अब तक मेरा समाधान regex के साथ है: 

  url = re.findall ('\ (' (*। *) '' \) ', सूप ['शैली']) [0]

आप पैकेज का उपयोग करने का प्रयास कर सकते हैं। इस तरह से कुछ काम करना चाहिए: 

  bs4 आयात से आयात cssutils BeautifulSoup html = "" "div class =" image "style =" background-image: url ('/ uploads / images / खिलाड़ियों / 16113-139 9107741.jpeg '); "" "सूप = खूबसूरत सूप (html) div_style = सूप। (' Div ') [' शैली '] शैली = cssutils.parseStyle (div_style) url = style [ 'पृष्ठभूमि-छवि']> gt; & gt; & gt; Url u'url (/uploads/images/players/16113-1399107741.jpeg) '& gt; & gt; & gt; Url = url.replace ('url (', '') .replace (')', '') # या regex / split / find / slice etc. & gt; & gt; & gt; यूआरएल यू '/ अपलोड्स / इमेज / प्लेयर्स / 16113-1399107741.jpeg'

यद्यपि आप को वास्तविक यूआरएल को पार्स करने की ज़रूरत है, लेकिन इस विधि में परिवर्तनों के लिए अधिक लचीला होना चाहिए एचटीएमएल। यदि आप वास्तव में स्ट्रिंग हेरफेर और रेगेक्स को नापसंद करते हैं, तो आप यूआरएल को इस चौराहे से बाहर खींच सकते हैं: 

  sheet = cssutils.css.CSSStyleSheet () sheet.add ("dummy_selector {% s}" % Div_style) url = list (cssutils.getUrls (शीट)) [0] & gt; & gt; & gt; Url u '/ अपलोड / चित्र / खिलाड़ी / 16113-1399107741.jpeg'

I have a problem with C sock send () / recv () do nothing if they are in non-debug mode. Even if std :: cout can not return their return value for some reason std :: cout is not working in my method I std: : Cerr can not even make a mistake It does not make sense to check that in GDB, because everything works perfectly as a virus in non-debug mode.

Go: Package main import "net / http" function main () {fs: = http.FileServer (http.Dir ("static / house")) Http: .handle ("/", fs) http.ListenAndServe (": 4747", zero)} directory: project / stable home Html edit.html project.go When I run it, the web page displays links to edit.html and home.html instead of displaying a static page from home.html is. What am I doing wrong. Is this the best way to serve files? I know that there are other ways like From the HTML / templates package, but I'm not sure what is the difference between each of these methods and when. Thanks! fancy main () {http.Handle ("/", http.FileServer (Http) .ir ("static")) http.ListenAndServe (": 4747", zero)} You do not need static / home , just Static . and when you do not have index.html in / static , the directory instead Content appears.

I want to use the front and rear camera at the same time in iOS development: when I take a photo back After the camera, the front camera can be opened and another can take a photo.
