How to convert html string to plain text without html tags in google app script?

Question

I'm new to google app script.

I was trying to convert html string to plain text without html tags in google app script using the reference in this question.

However, when I try to apply it to my script, it is not working as expected.

This is the script that I use:

function toStringFromHtml(html)
{
  
html = '<div>' + html + '</div>';
html = html.replace(/<br>/g,"");
var document = XmlService.parse(html);
var strText = XmlService.getPrettyFormat().format(document);
strText = strText.replace(/<[^>]*>/g,"");
return strText;
}

and this is the output:

While my actual expectation is in the third column.

Can someone tell me what is wrong with my previous script?

Thank you!

In your situation, for example, how about the following modification?

From:

return strText;

To:

return strText.trim();

Reference:

trim()

If you're running in a browser, then the easiest way is just to let the browser do it for you

function stripHtml(html)
{
   let tmp = document.createElement("DIV");
   tmp.innerHTML = html;
   return tmp.textContent || tmp.innerText || "";
}

Hi, thank you for the response. I tried using this and I got the error. Then I modify it a bit, and it's still error. Is this expected? The function that I use: function stripHtml(html) { html = '<div>' + html + '</div>'; html = html.replace(/<br>/g,""); var document = XmlService.parse(html); let tmp = document.createElement("DIV"); tmp.innerHTML = html; return tmp.textContent || tmp.innerText || ""; }

@Ninja -- is there a way to create a dummy HTML document for this purpose, so I can debug and run it on my desktop?
