您应该避免使用正则表达式解析 HTML.这是一种使用 DOM 删除所有 标签的方法:

You should avoid parsing HTML using regex. Here is a way of removing all the <a> tags using DOM:

// your HTML text
var myString = '<table><tr><td>Some text ...<a href="#">label...</a></td></tr></table>';
myString += '<table><tr><td>Some text ...<a href="#">label...</a></td></tr></table>'
myString += '<table><tr><td>Some text ...<a href="#">label...</a></td></tr></table>'

// create a new dov container
var div = document.createElement('div');

// assing your HTML to div's innerHTML
div.innerHTML = myString;

// get all <a> elements from div
var elements = div.getElementsByTagName('a');

// remove all <a> elements
while (elements[0])
   elements[0].parentNode.removeChild(elements[0])

// get div's innerHTML into a new variable
var repl = div.innerHTML;

// display it
console.log(repl)

/*
<table><tbody><tr><td>Some text ...</td></tr></tbody></table>
<table><tbody><tr><td>Some text ...</td></tr></tbody></table>
<table><tbody><tr><td>Some text ...</td></tr></tbody></table>
*/
