Find and Replace HTML Tags

How to replace a html tag in js?

text = text.replace(/<font[^>]*>/g,'<p>').replace(/<\/font>/g,'</p>');

Find/Replace regex to remove html tags

This works for me Notepad++ 5.8.6 (UNICODE)

Replace words in the body text

To replace a string in your HTML with another use the replace method on innerHTML:

document.body.innerHTML = document.body.innerHTML.replace('hello', 'hi');

Note that this will replace the first instance of hello throughout the body, including any instances in your HTML code (e.g. class names etc..), so use with caution - for better results, try restricting the scope of your replacement by targeting your code using document.getElementById or similar.

To replace all instances of the target string, use a simple regular expression with the global flag:

document.body.innerHTML = document.body.innerHTML.replace(/hello/g, 'hi');

Replace HTML tag with string that contains tag attribute

As you are in JavaScript, you have a DOM parser at your fingertips. Use it!

const container = document.createElement('div');
container.innerHTML = input;
const buttons = container.querySelectorAll("input[type=button]");
buttons.forEach(button=>{
  button.replaceWith("${"+button.value+"}");
});
const output = container.innerHTML;

How to replace text containing string with a HTML tag?

I assume you don't literally mean all text on a page, but rather all text inside of a given element. DucFilans is right on the money with regex, I'll slightly modify his answer to provide a complete working solution:

var parserRules = [  { pattern: /bold\("(.*?)"\)/g, replacement: '<b>$1</b>' },  { pattern: /italics\("(.*?)"\)/g, replacement: '<i>$1</i>' }];
document.querySelectorAll('.parse').forEach(function(tag) {  var inner = tag.innerHTML;  parserRules.forEach(function(rule) {    inner = inner.replace(rule.pattern, rule.replacement)  });  tag.innerHTML = inner;});

<div class='parse'>  <div>bold("Hello") world <p> Rose italics("pink") slow bold("!") </p> </div>  <div>bold("astiago") cheeeeeeese!</div></div>

Find and replace html tags using regex

You need to do a match to focus on the text between the dollar signs and then do the replace 'text'.match(/\$(.+)\$/)[1].replace(/(<.+?>)/g, '')

You can do .match(/\$(.+?)\$/)[1] if you have several PAIRS of dollars

replace string text with html tag using regex

I'm not sure this is what you really need. Anyway, I think it's a step closer.

I made a new regex to get '#' + words and for the text to be updated with replace it is necessary to play

text = text

Then:

import "./styles.css";

export default function App() {
    let text = "#Jim, Start editing to see some magic happen!";

    const regex = /\#[a-zA-Z]+/gm;
    text = text.replace(regex, (match) => {
        return `<span style="color: red">${match}</span>`;
    });
    return (
        <div className="App">
            <div
                dangerouslySetInnerHTML={{
                    __html: text
                }}
            />
        </div>
    );
}

Vscode Find & Replace a changing block of HTML code

The regex you're looking for in this case is:

VS Code supports regex base search & replace. Next to the search field, select the .* icon. Run the search and hit the 'replace' button, and you're done!
