Python uses regular expressions to parse and replace pictures in a Web page _python

This example describes how Python uses regular expressions to parse pictures in a Web page and replace them. Share to everyone for your reference. The specific analysis is as follows:

This code analyzes all the picture forms in the Web page , and then adds the appropriate cosmetic labels to them before and after parsing, and adds a hyperlink to the picture.

Copy Code code as follows:

result = Value.replace ("[Page]", ""). Replace (', U ')
P=re.compile (R ' ]*?\bsrc[\s\t\r\n]*=[\s\t\r\n]*[']?[ \s\t\r\n]* ([^\s\t\r\n "' <>]*") [^<>]*?/?] [\s\t\r\n]*>) ', Re. IGNORECASE)
result = P.sub (R ' "<span class=" Openicon "><em></em><a href=" \2 ">\1</a></span>" ", result)
