Hi,  
I put back in a XML file a string with many lines.  
But after record it I have only one lines.

```auto
txt.setContent(t.getTxt()); //txt is my xml node

```

Did you write this function? Then insert `"\n"`

I can’t help you with that.

I tried to modificate the getTxt() function like this :

```auto
 String getTxt() {
        String t[] = txt.split("\n");
        String t2[] = new String[t.length];
        String ft = "";
        for (int i=0; i<t.length; i++) {
            t2[i] = trim(t[i]);
            t2[i]+="\n";
            ft += t2[i];
        }
        return ft;
    }

```

But he forget always to write the ("\n") sign the xml.  
I think this function is useless.

</div>

you don’t provide enough context

Did you try

```auto
println(t.length);    

```

after `String t[] = txt.split("\n");` ?

Maybe t[] is empty?
