Question

I’m trying to change width value in the string using regex.

Width can have multiple formats, such as width="500px" or width:500px or width=500px (without quotes), etc..

Currently, I’m searching and replacing individually like this

p = re.compile('width="\w{3}')
embed_url = p.sub('width="555', embed_url)

# width:"555
p = re.compile('width:"\w{3}')
embed_url = p.sub('width:"555', embed_url)

Is there any way to use one regular expression and replace strings : or = accordingly?

EDIT

Changed the above code, so : and = is changed accordingly, instead of replacing all of them with “=”

Answer 1

Try this regex:

width(:|=)"?\w{3}

it matches:

width="300px
width=300px
width:"300px
width:300px
