Using DOM to scrape text with/without line break how ?

[2xdswu]

Hey there.
I'm scraping captions from instagram however I'm looking to scrape captions and using regular expressions with DOM is giving me issues.

For example there's over 20 photo's captions some have and some don't have line break.

I'm using this:

(?<=<img\ alt=")[\w\W]*(?="\ class="_icyx7"\ id="pImage_8")

But it only works for captions with linebreak and

if I use this:

(?<=<img\ alt=").*(?="\ class="_icyx7"\ id="pImage_8")

It'll not scrape the photo's without line break.

is it possible for me to do like [\w\W] or .* ?
