Getting text from source code

[Adrian Sadkowski]

Hey guys,
Maybe someone has an idea how can I:
1. get source code of a webpage in MIT app inventor (web-component is ok?)
2. find particular phrase in this code
3. paste it into aplication for exaple as "Label"
I've got to copy a text from a page and this page doesn't offer API.

Maybe this would be useful "How to parse a result" (https://puravidaapps.com/snippets.php#2parse). I just want to use source code instead of "string".

set Web.Url to http:///example.com/yourPage.html

Web.get

and in the Web.GotText event receive the source code of that page and use the parse procedure

I used web component and set url but i don't understand what do you mean by "and in the Web.GotText event receive the source code of that page and use the parse procedure"
i don't know how to connect procedure and web.gottext.

[Taifun]

the string in your case is the response content of the web.gottext event

• How to parse a result

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook   http://www.appinventor.org/book2 ... the links are at the bottom of the Web page.  The book 'teaches' users how to program with AI2 blocks.

There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro  and the aia files for the projects in the book are here:  http://www.appinventor.org/bookFiles  

How to do a lot of basic things with App Inventor are described here:  http://www.appinventor.org/content/howDoYou/eventHandling  .

Also do the tutorials http://appinventor.mit.edu/explore/ai2/tutorials.html to learn the basics of App Inventor, then try something and follow the

 Top 5 Tips: How to learn  App Inventor

You will not find a tutorial, which does exactly what you are looking for. But doing the tutorials (not only reading a little bit) help you to understand, how things are working. This is important and this is the first step to do.

Thanks for help :)

Should it look like this?

[Taifun]

the url should be defined somewhere else, for example in a button.click event

also you forgot to use the Web.Get method

before being able to receive something in the web.gottext event, you first have to call Web.Get

ABG probably would explain it like this:

first you have to say "please give me some candy" (Web.Get) and then a little bit later you will get it (in the Web.GotText event)

btw. it helps to do the tutorials...
