The Project im working on is about the visualisating of SMS Text messages. All the information is saved in TXT files. Each SMS is a textfile wich contains all the information needed.

I made some tests with the method explained in the "LoadFile 1 tutorial" in the Learning Section. It works pretty good. But there i need all the information in one large file, every sms information in one line, seperated by a seperator.

Are there different ways to get the specific part of the file then "split(lines[index], '\t');" ?

For example this is how a file looks like:

Quote:


So is there a way to say, get data after "FROM:"
or get data between " "Size:" and "bytes" ?

Like i said i could find any references or information on how to get data out of files expect the "loadfile 1" example.

If there is no way, is there a way or software to konvert all the data out of the files into one single file to one line per File and seperate them the way i want. Or how do you edit data to work the way you need it.

Thank you for helping!

loadString() loads the whole file at once and splits it by lines. It is OK if the file isn't huge (below memory allocated to Java...), otherwise you might need to use Java's line per line reading.
Say loadString is what you need.

You make a loop to scan all the lines in the returned array.
You can take the first n character of the line (using substring as shown) and compare to known prefixes (From:, To:, Subject:, etc.).
You can also split the line on ' ' instead of '\t' and check the first returned string. Slightly less efficient but simpler.

Your sms object is an array of strings, not just a single string so you need to specify which line of the sms array you're trying to work on.

e.g.
Code:

String size=sms[0].substring(6,sms[0].length-6);
 

sometimes it's also better to use indexOf() and match() too, depending on what you're trying to do.

for lines that begin with something followed by a colon (an attribute followed by a value), you can use:

Code:

int colon = lines[i].indexOf(':');
String attr = lines[i].substring(0, colon);
String value = lines[i].substring(colon + 1);
 

then to use the information:
Code:

if (attr.equals("From")) {
  // the 'value' is the from line
}
 

this way you don't have to hardwire things for number of letters and all that.

or to get into trickier matching methods, you can use the match() function:
http://processing.org/reference/match_.html

this breaks the line into a two piece String array:
Code:

String line = "From: Jim Bob Jones <jim.bob@the-hills.net>";
String[] pieces = match(line, "(.*):(.*)");
println(pieces);
 

(more about the syntax for match is in the reference)
