TomDuncan · Oct 12, 2015

Hi All,
Is their an easy to to encode or decode Quoted printable data.
This is the body of an email.

Also with this body the body itself is being truncated.
This is how it ends ..

B4X:

</blockquote><blockquote type=3D"cite"><di

where this is what came in..

B4X:

<html><head><meta http-equiv=3D"content-type" content=3D"text/html; charset=3D=
utf-8"></head><body dir=3D"auto"><div>Check it out<br><br>Tom Duncan<div>Sen=

Did you just want it in clean html code ?

<body>
<meta http-equiv="content-type" content="text/html; charset=utf-8">

Yes, exactly.
To Display an email in html format.
It does have funny "=" and 3D bits as well.
However, I think their is an error in the mail parse routine which is chopping off the tail of the body.
Might have to ask another question for that.
It is used in the pop email handling.

To clean up the data I just used

B4X:

Dim outstring As String = ""
outstring = s.Replace("="&Chr(10),"").Replace("=3D","=")
outstring = outstring.Replace("&lt;","").Replace("&gt;","").Replace("&amp;","&")
outstring = outstring.Replace("%2F","/").Replace("ahref","a href")

Where s is the input string.
I then used 'jSoup' (from jsoup.org) to parse it into a readable format. (it can also search the document for elements)

B4X:

#if java
import org.jsoup.Jsoup;
import org.jsoup.helper.Validate;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

public static String decode(String s){
  Document doc = Jsoup.parseBodyFragment(s);
  Element body = doc.body();
  return body.toString();
}
#end if

That looks nice and easy, thanks will test in the morning.
The code came from the b4j mail program.
It was an e-mail that came to me and looked difficult to parse.

So with jsoup if I used the entire email and used that to grab the body?

Yes, or you can specify which parts you want.
eg,

B4X:

// in java code
Element block = doc.select("blockquote[type=cite]).first();
return block.toString();

Will return the first blockquote with a type equal to 'cite'

The truncation could be caused by the buffer being too small if that's how it reads the data from the pop3 server.

Will check that as well, thanks.
