How to

Use the webpage we used on the practical: https://regex101.com/#python

All you need to send is the regex (that you wrote in the regular expression box on the website).

Regex links (3 points)

Write a regular expression that finds links in an html code. We can assume that links:

  • start with http://
  • apart from alphanumeric characters only contain the following characters:
    • / (per),
    • . (dot),
    • ~ (tilde).


For example, in the following code it only finds the 4 links:

 <div>
 	<div id="header_col2"> 
 		<a href="index_en.xhtml" title="English version"> 
 			<img src="eng.jpg" alt="English" height="25" width="48"/>
 		</a>
 	</div>
 </div>
 <div id="clear">
 <hr/>
 	<h2> Some links </h2>
 	<p>
 		<a href="http://www.math.bme.hu/algebra">Department of Algebra</a><br/>
 		<a href="http://www.math.bme.hu/">Matematics Institude</a><br/>
 		<a href="http://www.bme.hu/">BME</a> <br/>
 		<a href="http://www.bme.hu/~kk0v4cs">Something else</a> <br/>
 	</p>
 </div>
