how do i trim empty text elements from a html string?

Question

What is the easiest way, without using regex, to trim empty text elements and line breaks from a html string using c# ?

When I say trim I mean from the start and end of the html

example

input:

<br /><br /><p></p><h1>Title</h1><p></p><br /><p>paragraph</p><p></p><p></p><br />

output:

<h1>Title</h1><p></p><br/><p>paragraph</p>

Update: I think I misread your question. How do you define an empty text element? Why is `
` empty but `
` is not? — Datz, Oct 30 '18 at 11:31
Why do you keep the empty `p`-tags in the middle? I'd use HtmlAgilityPack if i had to parse HTML. — Tim Schmelter, Oct 30 '18 at 11:31
thank you for your comments! i have edited the question to reflect the comments. — Stian Standahl, Oct 30 '18 at 11:33
@TimSchmelter the p tag in the middle is to show that this element should not be removed. — Stian Standahl, Oct 30 '18 at 11:34

I am not sure, if you are looking for a tool or whatever, but I think a regular expression like this could work:

/<[^>]*><\\/[^>]*>/

should have been more precise. I wanted a way without using regex. – Stian Standahl Oct 30 '18 at 11:31
