如何转义非标准（无效）HTML 标签？

Question

I get a response from API that might contain HTML tags and I need to render those tags and I use angular directive [innerHTML] and it works perfectly, for the most part, the problem starts when the string is something like this:

Test string, I am saying <hello>

[innerHTML] treats <hello> as a valid HTML tag and the output on the screen is something like this:

Test string, I am saying

<hello> is not a standard HTML tag and if there is a non-standard HTML tag in the string I want to escape those tags and this should be the output:

Test string, I am saying <hello>

Any library to accomplish this task, I want to know if there is any pre-existing solution for this?

Answer 1

Quote the character < in front of hello as < .
