How to get the right attrs of

Question

I write a Regex to get the attrs in a tag. But it got a problem when the attrs only has one letter

(\S+)=["']?((?:.(?!["']?\s+(?:\S+)=|[']?[>"]))+.)["']?

When it to analysis this:

href='www.google.com' target="_blank" title="S"

it will get:

[[href, www.google.com],[target, _blank],[title, "S]]

How can I get:

[[href, www.google.com],[target, _blank],[title, S]]

Don't use regex to parse HTML. It rarely ends well. See https://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454 — 3Dave, Jul 26 '19 at 02:03
If you can, use a proper HTML parser instead of regular expressions. What programming language are you using? — truth, Jul 26 '19 at 02:04
Your regularity is very complicated, try this:`(\S+)=["']([^"']+)` [demo](https://regex101.com/r/jqYuuq/1) — Oliver Hao, Jul 26 '19 at 02:46
(\S+)=["']([^"']+) not work for href="javascript:alert('Hello');" — Victor Hong, Jul 26 '19 at 04:29

This expression might return the desired outcomes:

([^=]+)=["']([^'"]*)["']

Other options would be:

(\S+)="(.*?)"|(\S+)='(.*?)'

(\S+)="([^"\r\n]+)"|(\S+)='([^'\r\n]+)'

Thanks for the reply, but it does not work for href=\"javascript:alert('Hello');\", it will get javascript:alert( – Victor Hong Jul 26 '19 at 04:22

Sorry, actually I only need to handle this href="javascript:alert('Hello');" – Victor Hong Jul 26 '19 at 04:45
