Is it possible with javascript to read a textfile and change there a certain string in a certain line?

I looked at the jsfiletester example. So I know how to read and write a file.

But how can I load the content of the txt file to a variable?

The best would be a find and replace object ;-)

I?m new to max and javascript as well...

find-and-replace-in-a-txt-file-xml-file

    var f = new File(s,"write","TEXT"); 

        post("writing string to file: " + s2 + "n");

        post("could not create file: " + s + "n");

i want to write an XML file. i have already the content of it. so i just have to paste it into the variables. but not so easy as expected...

if i paste the XML file to the variable JS has problems with the newlines and shift rights in the XML...

I attached the XML file which is basically a MOTION2 file. So you can try to paste it to one of the variables...

I also tried to get away with the newlines of the XML in the text editor but it won?t help. 

? error: js: jsfiletester.js: Javascript SyntaxError: unterminated string literal, line 26

function writefile(s)
{
	var f = new File(s,"write","TEXT"); 
	var s1 = 'test';
	var s2 = 'this';
	var s3 = 'text';

	if (f.isopen) {
		post("writing string to file: " + s2 + "n");
		f.writestring(s1); 
		f.writestring(s2); 
		f.writestring(s3); 
		f.close();
	} else {
		post("could not create file: " + s + "n");
	}

I still get some error code like this:

sorry for the aweful selftalk topic ;-) but...

hey I?m very proud to present the find and replace script:

    var w = new File(w,"write","TEXT"); 

        while (a=r.readline()) { // returns a string

            post("line[" + i + "]: " + a + "n");

            if (a.search(/clip02.mov+/) != -1) 

            {neu = a.replace(/clip02.mov/, clip);

        post("could not open file: " + s + "n");

the only thing I don?t know yet, is how to save the new file in a certain folder...

I guess in the file name the full path should be inserted... 

var w = new File("/your/full/path/to/the/folder/"+w,"write","TEXT");

You can make the user give the path to write, by using the object to get a folder path...

btw... Got here because I didn't know how to read and edit files in js...
