I have this string in javascript.
var X = "<tr><td>pro</td><td>intel</td><td>234</td></tr>"
How can I retrieve the value 234 to another variable from that string?
You've heard the disclaimers about parsing html with regex, but if you want regex, with your input, you can use this pattern:
[^><]+(?=<\/td><\/tr>)
In JS:
var myregex = /[^><]+(?=<\/td><\/tr>)/;
var matchArray = myregex.exec(yourString);
if (matchArray != null) {
thematch = matchArray[0];
}
