Discard inner text of tag containing custom data attribute

[pjebs]

Feature request:
If a tag contains a custom data attribute

Eg

<div data-danger>...</div>

Configure to discard the inner contents.

You should be able to do this with the existing transformTags option.

I meant something more like this:

If it encounters a custom data attribute: data-keep, it keeps the inner text.
If it doesn't encounter it, it removes the text inside the tag.

const html = "<div data-keep>...sadgasg<div>ABCDEF</div></div>";

Should produce:

"<div data-keep>...sadgasg<div></div></div>" or maybe even "<div>...sadgasg<div></div></div>"

text: '' doesn't seem to work

sanitizeHtml(html,  {
  transformTags: {
    '*': function(tagName, attribs) {
      if (attribs.hasOwnProperty("data-keep")) {
        return {
          tagName: tagName,
        }
      } else {
        return {
          tagName: tagName,
          text: ''
        }
      }
    },
  }
})
