I want to use regex to check if an HTML document contains at least one of all the tags below:

<b> [content1] </b>
and

<i> [content2] </i>
and

<b> [content3] <i> [content4] </i> [content5] </b>
or

<i> [content6] <b> [content7] </b> [content8] </i>

'content' can be anything. Is there a way to achieve this
