Html – Regular expression to find words that begin and end with

Good evening, (sorry for my English is not my native language) I’d like to find words in HTML text.
I don’t get what I want and I ask for help. Sample text:


<div class="text-slate-500 text-white text-5xl bg-white bg-slate-600 bg-red/5 ....."> </div>

I should like to find only the words that begin with bg- or text- and ends with 0

This is the best result I’ve been able to get,
but what’s missing to find final 0?

b(bg-w*)b

b(text-w*)b

😀 Thanks for help!

I’ve tried several formulas found on the net, I’ve tried to look for other posts here but I couldn’t get anything better.

/(bg.*00)/g

    Try b(bg-[w-]*0)b. - isn’t covered by w and thus your existing patterns would not match bg-slate-600, so we add it in as a possibility in a list with [w-]. This is the same as [a-zA-Z0-9_-]. Then add 0 to the end of the capture group before the word boundary (b) for the stipulation that it should match an ending 0.

    you can try this:

    /(bg)+(-[a-zA-Z0-9]*)+0/g

    This pattern should accurately match your requirement:

    /bbg-(w+-)+d0{2}b/g
    • b word boundary (start of word)
    • bg- literal match for characters b, g, and - (hyphen)
    • ( )+ one or more:
      • w+ one or more word-characters
        • same as [0-9A-Za-z]+
      • - hyphen (literal match)
    • d one digit
      • same as [0-9]
    • 0{2} number zero 0 (literal match)
      • {2} two times
      • same as 00
    • b word boundary (end of word)
    • g flag – global search (find all matches)
