I'm trying to pull an image source url from a html source file. I'm new with regex. I'm in BaSH. I've tried
which highlights the text, but gives me 2 problems:
1) Results aren't stand alone and can't be piped to another command. (I believe it includes everything in results between line breaks)
2) It includes spaces. This is an issue when there's an anchor before the image, and it counts from href='http.....'><img src.....jpg
I've tried putting lookbehind in there
I either get errors or nothing returned. I don't know if it's something simple or not, but any help would be appreciated. I'm not opposed to sed or awk, but my knowledge of them is basically clean slate.
Also, this is *NOT* a homework assignment. It's me trying to learn by doing and hitting a wall repeatedly. Thanks for the help!!!
