How to parse a given key-value parameters string?

Question

I have this string:

Parameter1="Something related to this" Parameter2="Another value" Parameter3='Single quotes are permitted' Parameter4="Even HTML entities are permitted"

I want to get this list:

1. Parameter1=Something related to this
2. Parameter2=Another value
3. Parameter3=Single quotes are permitted
4. Parameter4=Even HTML entities are permitted

I tried this regex. But it's not working:

(\w+)=(('|"|")).*(('|"|"))

How can I parse this string and extract key-value pairs?

Answer 1

You can use

(\w+)=(['"]|")(.*?)\2

See the regex demo . Details :

• (\w+) - Group 1: one or more word chars
• = - an equals sign
• (['"]|") - Group 2: ' , " or "
• (.*?) - Group 3: any zero or more chars other than an LF char as few as possible
• \2 - Group 2 value.
