I have an application which takes live data from internet,
I want to develop another application which reads data from the internet and writes it
to an XML file (i.e. I want to save the state in an XML file).
THE ONLY THING I NEED IS HOW TO WRITE THIS DATA IN AN XML FILE. I WANT TO SAVE THE XML FILE
ON LOCAL DRIVE (SAY C: DRIVE OR D: DRIVE BUT ON LOCAL HARD DRIVE
FOR EXAMPLE say I have a combo box which takes top 10 fifa world cup watching sites,
now I want to write this information (i.e. whatever the data this combo box takes as input
into an xml file).
I want the answer in flex only. And I don't want answer in AIR.
Thankyou in advance.
How about FileReference::save ?

I'm still getting into google spreadsheets, recently understood how to format a .txt to be able to use =ImportData properly thanks to Tanaike's assitance, now tackling a -slightly- more challenging task.
Goal:
Automatically extracting specific data from .pdf files hosted inside of a google drive folder and arranging the information into specific cells
Challenges:
Being able to decode the blobs of information, as just the raw data obtained with =ImportData is useless
Truly learning how to use google-apps-script for something useful (that's on my own)
Instructing a single extraction of information rather than constant online status as with =ImportData
[Second Priority] Stop Depending on an add-on (Drive Direct Links) to get the URL of the files
To my understanding, I'll need to do some parsing. I know .pdf is not always straight forward, all the files will come from the same place and have the exact same format, so understanding how to do it once should be enough.
I already know how to get the real/permanent link to the files automatically and how to arrange information segregated into cells using =Index, =Extract and others.
Hope I'm being clear enough. Thanks a lot in advance.

I have created an app using ionic and cordova and now I want to remake it on iOS. I am working with iOS for the first time, and I cannot figure out how to store data.
For example: I have a form where user has to input some data, but the inputs are not in one view, there must be several views. I used to create empty array and just put everything step by step, but now i can't use same view controller on multiple views. Tried to do it with core data, but core data cannot store arrays. My object would look something like this:
var sampleArray = (
duration: 13,
dayOfTheWeek: Thursday,
personList: [
(name: Rocky,
age: 26),
(name: Ralph,
age:23)
]
)
The question would be: How could I make an input form which would be on several views and where should I store the data, and later I would be able to store all the data into core data?
You can work with persistent data in several ways on iOS.
User Default
This is a tool that is used to store small amounts of information like user settings, preferences etc. Don't use it for data that will scale with application usage (e.g. like notes in notepad app). Documentation will answer all your questions about User Defaults.
Database
You have Core Data as an out of the box solution which is build on top of the SQLite and takes some time to learn, but from my experience it's worth the effort. You are free to use pure SQLite or other database type, but it requires more code and probably custom frameworks.
Text files
You can use arbitrary XML, JSON or CSV files to store your data. Tooling is rich (e.g. NSXMLParser or SwifyJSON just to name two) and if you look on Github, you will find what you need. You can also use build in combination of NSCoder and NSKeyArchiver / NSKeyUnarchiver which are easy to grasp.
Binary files
Finally, for a local storage you can use binary files i.e. images. This is too advanced topic to cover here, but I want to share an example of Open Raster file format. It is used to save informations for drawing apps (eq. GIMP) and inside, it is basically an XML file and a bunch of images compressed to zip and named as .ora file. Creating your own specification for a hybrid format is not that hard.
Network repository
Just to not overlook other methods, you can use remote database API to store data outside of the device, but of course you need your own host and some backend skills.
I hope I didn't miss something important. I just wanted to sum up this knowledge in one place for future reference.
As the first comment says, your question is quite large.
When you say 'one form on several view', I consider it as 'one form per view'.
Keep It Simple S... ;)
(Except if you use page control for your form.)
Basically, you have three ways to store data :
NSUserDefaults :
Store data in Dictionary for later use
File :
Save data to a File (why not .csv like ?)
CoreData :
You can persist arrays as binary data in Core Data
There are numerous tutorials on these topics.

I have an app (written in D2010) which is similar to a text retrieval app... It has a list of questions, with their corresponding answers. Most answers are strictly text, but some answers have graphics, and formatting. My dilemma has to do with the formatted answer. The user should be able to copy this answer (formatting and graphics) in order to paste it into another app. I have tried using a Word OCX. This is a little problematic. User has to have word, it gives random errors when using inside a virtual machine, etc. I am now playing with using a built in browser component, and viewing the data as a PDF. This is nice and easy, but when I copy and paste it, I loose all formatting, and the graphic shows up as a large totally black box.
I can store the data in whatever format I choose. It is stored as a BLOB in a DB file. I write it to a temp file and then I call some type of viewing routine, so I have flexibility there. My issue is really, what viewer mechanism is simple to implement, and allows copying/pasting, while maintaining text formatting (bullets, indents, etc) and graphics.
Thanks,

The TRichEdit (or any of TRichEdit descendants or similar classes) will allow the users to visualize text formatting and images, and when the content is copied, the RTF representation of the data will be copied into the clipboard.
When the clipboard data is pasted into a RTF compatible text editor (like Wordpad and Word), all the formatting, bullets and images are preserved.
How do the applications transfer the copied strings into each other? Is this a clipboard usage? If so, how can i access the clipboard in a program?
Edit: I'm interested in Windows systems, I know a bit of C#, and C++.
Yes, cut-and-paste is usually done using the system-wide clipboard.
In both Windows Forms and WPF applications, there are (different) classes called 'Clipboard', which contain the stuff you need to access the system clipboard.
Basically, the clipboard allows you to put pretty much anything on to it, along with markers that say what format the data is in. You can put the same data on in lots of different formats. That's how, for example, you can cut and paste a part of a spreadsheet in Excel into Notepad - Excel has put the data onto the clipboard in both a native Excel format and a plain text format.
