VisualizaçõesRegex match just first result or second from HTML table
I'm using regex in-app script javascript. I try to get just the first value or the second value from each table but not work.
<table>
<td class="bar">
<td class="center">hello1</td>
<td class="center">hello2</td>
<td class="center">hello3</td>
</td>
</table>
<table>
<td class="bar">
<td class="center">hello1</td>
<td class="center">hello2</td>
<td class="center">hello3</td>
</td>
</table>
my code regex: /(?<=<td class=\"center\">).*?(?=<\/td>)/gi
this code selects all values Hello. I want just select Hello1 from the first table td and second table td. I remove global but give me just the first td from the first table.
the hello value is dynamic not fixed.

You could do a regular expression something like this which retrieves the text you expect...
Essentially matching the tags by excluding <> characters within the tag.
However I think an easier and less error prone way to do this in JavaScript and DOM is to use querySelectorAll instead, for example...
let c = document.querySelectorAll('td:nth-of-type(2)');
console.log(Array.from(c).map(i => i.innerText)); <table>
<td class="bar">
<td class="center">hello1</td>
<td class="center">hello2</td>
<td class="center">hello3</td>
</td>
</table>
<table>
<td class="bar">
<td class="center">hello1</td>
<td class="center">hello2</td>
<td class="center">hello3</td>
</td>
</table>
