Does any one of you know a solution to either read or edit on an iPad files stored with Textedit on iCloud ?
As @patrix said there is no way.
However you can use iA Writer. It's an application available for Mac, iPad and iPhone, which allows you to read and write
txt files, which are the same produced by Textedit. It as a native iCloud and Dropbox support.
Unfortunately it is not free.
Alternatively Brett Terpstra has an amazingly comprehensive review of iOS editors where you can find a replacement or be alerted when a program does in fact cooperate with TextEdit for document storage in iCloud.
using iCloud Drive w/ iOS 9 it is possible.
"On your iPhone, iPad, or iPod touch with iOS 9, you can access your files from the iCloud Drive app. To show or hide the app, go to Settings > iCloud > iCloud Drive. Next to Show on Home Screen, choose On or Off. On your PC with Windows 7 or later and iCloud for Windows, you can go to iCloud Drive in File Explorer"
