Android Question remove all htlm tags from a string

[luke2012]

Hi all,
is there a quick solution to "clean" a string removing all html tags to got a plain text without any tag (see example) ?

<p class="text-align-justify">Multibrand giovane con i migliori marchi come....</p>

For this specific string the fastest solution is...

'str is the above string
str.Replace($"<p class="text-align-justify">"$, "").Replace($"</p>"$, "")

But this is good only for this specific string, if the tags change it is no longer guaranteed that the string is text without HTLM.

So wich is the best solution in this case ?

1) regex (is there any pattern to remove all HTML tags) ?
2) HTML parser (parsing the tags to extract the text) ?

Maybe this Lib can help?
At least i found a reference to jsoup using google. And this is a lib about jsoup.

Use a HTML parser. Here's a Jsoup example.
String input = "<font size=\"5\"><p>some text</p>\n<p>another text</p></font>";
String stripped = Jsoup.parse(input).text();
System.out.println(stripped);

Result:
some text another text

jSoup HTML Parser

This is my first attempt at a wrapper so it's a work in progress. Consider it a Beta although it isn't feature complete, I'm adding features as I require them :) Not all functions and documentation implemented or tested fully yet. Library is compatible with B4A and B4J. 1. Download jsoup...

Don´t know if this lib has support for parse(input).text() though.

I use an HTML sanitizer library. Let me see if I've posted it here.

Here you go, not sure if it works on B4A as I only use it on B4J

Dim Html As String = $"<!DOCTYPE html>
<html>
<body>

<h1>My First Heading</h1>
<p>My first paragraph.</p>

</body>
</html>"$
 
Log(Regex.Replace("<[^>]*>",Html,""))

My First Heading
My first paragraph.
