Android Question HTML inner text

Rusty · Nov 1, 2016

Is there a way to get the inner text of an HTML document?

I need to get the "text" of the HTML with none of the actual HTML

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<body style="font-family: Calibri">
<p class="style2">
<strong>Dear Sir:</strong>
</p>
</body>
</html>

I'd like to retrieve ONLY "Dear Sir:"
Thanks

The question is whether all the html texts that you need to deal with look exactly like the above snippet?

If so then you can easily get this value with regex:

B4X:

Sub Button1_Click
   Dim html As String = $"
   <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<body style="font-family: Calibri">
<p class="style2">
<strong>Dear Sir:</strong>
</p>
</body>
</html>
"$
   Dim m As Matcher = Regex.Matcher("<strong>([^>]+)</strong>", html)
   If m.Find Then
     Log(m.Group(1))
   End If
End Sub

Another option is to use JTidy to convert the html to XML and then parse it with a XML parser.

of course they are not all like that

it was a simple example.
However, your suggestion of JTIDY was excellent! Much better than the REGEX I've been using!
Thanks,
