Python USES regular expressions to analyze and replace images in web pages

This example shows how python USES regular expressions to analyze and replace images in web pages. Share with you for your reference. Specific analysis is as follows:

This code analyzes all the picture forms in the web page < img > After analysis, add corresponding decoration tags before and after it, and add to the hyperlink of the picture.

result = value.replace("[ page ]","").replace('  ',u'　')

p=re.compile(r'''(<imgb[^<>]*?bsrc[strn]*=[strn]*["']?[strn]*([^strn"'<>]*)[^<>]*?/?[strn]*>)''',re.IGNORECASE)

result = p.sub(r'''<span class="openIcon"><em></em><a href="2">1</a></span>''',result)
