Is it possible to read partial data of a txt file?

MIT App Inventor Help

Hello, I am a newcomer and I want to load a txt file to my app. After loading the txt file I don't want to read every data/sentence that is written in the txt file. Is this possible? There are some unwanted data and sentences are written on the file. I learned how to load and read txt file but I cannot find partial reading of uploaded file. Maybe there are some filters for this. Thanks for help

No, the file component can only read the complete file

Thanks for the answer, Is there a possible way to get only one data in the excel file? If I can give the row and column index can I get only one data?

Do you want to read first n bytes of the file or somewhere middle in the file?

Hi @Kumaraswamy i read the post, and i get interested in the topic, how can we READ and TAKE some info from (somewhere middle in the file)?
It's like scrapping.
I need to take only a Math VALUE like a constant, only change with some circumstances.
This is in html files and in txt too (like log files).
I don't like the idea of scrapping, because i am not doing it in an illegal way (sound illegally and i don't want it, like this), but the web cannot share the info in a good way, the api i use, it's messy and do not share the info in a proper way.
If you like i can write you by mp and i can tell you the context.
The app is for educational purpose.

Hello, let's say I created a txt file and write something like "Status: Clear , ID:255". Now I want to get word "Clear" only. Or maybe I want "255" or "ID:255". I think my question is better now.

Maybe JSON and dictionaries would work for you?

Provide example text file content

Hello It is confidential but I made similar example for your question.
example.txt (161 Bytes)

Let's say I want to take "ProductIDVer=9" under the [ID] and "ControlEnabled=1" under the [1].

You can use a regular expression to search the text, after reading the text file, with a
regular expressions extension.

Either switch to a standard JSON file format to benefit from dictionary functionality or search this board for samples of my 'shred' procedure.
