Content are coming form WordPress site, In WordPress front-end showing fine , only problem in ionic

How to remove kindly suggest me.

If you don’t get any better answers, and you’re using [innerHTML], my advice is “redesign your app so you aren’t doing that”.

Kindly can you advise me what should be used instated of [innerHTML], If I’ll not use [innerHTML] then all HTML tag will show in app.

Here is what I suggest for these sorts of situations.
