[HELP JAVASCRIPT] Delete in a table the texts containing a "Yy" prefix

Hello,

Is it possible to help me with a program?

I would like to delete in a table all the texts containing a "Yy" prefix like the words "Yycar", "Yytravel", etc...

I developped a code but it doesn't seem to work at runtime, if you have a track I will be totally grateful to you 🙂

Here is my code:

// recovery. of all <td> 
const oCells = document.querySelectorAll("table td");
const search = "Yy";
// the search loop
for (let cell of oCells) {
  const text = cell.textContent;      // reading raw content
  if (text.startsWith(search)) {      // occurrence found
    cell.textContent = " ";       // we replace the content with nothing
  }
}

This JavaScript code will be used on a PDF document containing a table with data and I would like to delete in this table all the texts containing the prefix "Yy". 

Thanks in advance for your reply and have a nice day!
