Find html tags using RegEx in JavaScript

Question

I need to fing all "table" tags on page with attribute border on the page using Regular Expressions on JavaScript.

How can I do it?

P.S. Please, don't propose me any JQuery (or similar) solutions.

Have you taken a look at .querySelector? You can use CSS selectors to match what you want, without regex. — evolutionxbox

yes you can use regex like this. <table.*?border.*?>.*?</table> — Raghavendra

Why can't you use native JS methods? How do you expect to do anything without being able to use native JS? Also, I don't think the querySelector is DOM manipulation. — evolutionxbox

@StasKh It's a trick. Tell your mentor that you should use the appropriate tool for the task. — CodingIntrigue

you can use regex object like this to match table which has border.

myTableElement.match(/<table.*?border.*?>.*?<\/table>/gi)

or like this

var x =  new RegExp(/<table.*?border.*?>.*?<\/table>/gi)

myTableElement.match(x);

Sorry, how can I select all table tags with any attributes except border attribute?

Raghavendra Over a year ago

you can use new RegExp(/<table\s+border=['"].*?['"]\s+>.*<\/table>/)

Although I'm not the down voter, the reason is probably that you're a enabler. You're giving OP the answer where he is approaching the problem with wrong idea. There is no reason, ever, why you would have to use regex to parse html. Especially with powerful javascript api in browsers, like document.querySelectorAll. If this is a homework, stack overflow isn't the right place and whoever gave the homework should read about regexes and how they are not meant for parsing html.
