Android xml generate

i want develop an application that generate a xml like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

macrì11_files\a.bmp macrì11_files\b.bmp macrì11_files\s.bmp macrì11_files\t.bmp macrì11_files\u.bmp macrì11_files\v.bmp macrì11_files\z.bmp macrì11_files\za.bmp macrì11_files\zr.bmp macrì11_files\zs.bmp macrì11_files\zu.bmp macrì11_files\zv.bmp macrì11_files\zz.bmp macrì11_files\zzg.bmp

i have used this code but i have some problems..

the code is this:

try {
            FileOutputStream fos = new  FileOutputStream("userData.xml");
            FileOutputStream fileos= getApplicationContext().openFileOutput(xmlFile, Context.MODE_PRIVATE);
            XmlSerializer xmlSerializer = Xml.newSerializer();              
            StringWriter writer = new StringWriter();
            xmlSerializer.setOutput(writer);

            xmlSerializer.startDocument("UTF-8", true);
            xmlSerializer.startTag("xmml publish", "1.0");
            xmlSerializer.startTag("xmedia _id", "f584ebd07e7542628e48da144ea9c412");
            xmlSerializer.startTag("program _id", "8cbbcaae48cb44bebefeea29d87e8559~1");





            xmlSerializer.endDocument();
            xmlSerializer.flush();
            String dataWrite = writer.toString();
            fileos.write(dataWrite.getBytes());
            fileos.close();
        }

one of my problems is: how i can write this line? it is very long for one xmlSerializer.startTag

What i can use?

Very thanks
