How to read specific line in a html Page ?

[MalcomJPrince]

Hello @ all

i try with the  Tutorial from http://puravidaapps.com/info.php to finde the line of this stream http://balkan.dj.topstream.net:8070/index.html,
but i dont find the line Current Song: with the next textinfo.
Can anyone help me ?

Thx

the info example helps you to get some Device specific info with App Inventor, so I'm not sure how that example can help you to "find the line Current Song"?

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

i try to show in my Radioapp the Current Playing Songtitel ( ID3 ) from a Stream like this site http://balkan.dj.topstream.net:8070/index.html.
i do a misstake and delete the new blocks.

here i found the way to your Guide :)

What i try is to show infos from the Radio stream what is inside the ID3 Tag.

You might start with this AI Classic example which uses a php script.

There may be an example somewhere which uses javascript instead.

thx Scott, but the test page looks like offline "http://www.aiapis.co.cc/read_id3.php?fn="
for this method i need a server with php.
Is there no possibility to read the Current Song: info from the shoutcast server info page like this http://balkan.dj.topstream.net:8070/index.html .
Like finde Text "Current Song:" and show the next text after this on a html page ?

If this isnt Possible in AI 1/2  i stop this part and make other futures in my App.

Thank you @ All

Hi,

You need virtualserver with php support for this.

Then you have 2 choices:

1. You show those pages throu webwiever component, pages have refresh meta tags that load new song info every 10sec.

2. If you need only current song name without any style, you can use Web -> get  from file http://peep.prants.ee/BALKAN.DJ/current2.php

you need to set Clock coponent to refresh song info.

(Please note! These files in my server is temporary)

Sample AIA and apk in attachment.

If you need php files then I need some Donation to PayPal

Hello Pepp, this looks nice.

I need for this a sql server ?

Hi, Sql server not required.

[muj...@googlemail.com]

but i need a php supportet server, i dont have one.

i create the app again with Android Studio, there i kann put a read id3 tag script.

thx

Yes.

Use the Web component with the Get block and GotText block to get the text of the page in the responseContent variable.

The use a web scraper to select the text between the start and end text on the page:

Start text -  "Song: </font></td><td><font class=default><b>"

End text - "</b>"
