How to make XML document from string in java or Android? -

i trying create dynamically generated xml file java. code trying use:

try{             bufferedreader bf = new bufferedreader(new inputstreamreader(system.in));              system.out.println("how many elements: ");             string str = bf.readline();             int no = integer.parseint(str);              system.out.println("enetr root: ");             string root = bf.readline();              documentbuilderfactory dbf = documentbuilderfactory.newinstance();             documentbuilder db = dbf.newdocumentbuilder();             document d1 = db.newdocument();             element e1 = d1.createelement(root);             d1.appendchild(e1);              (int = 0; < no; i++) {                 system.out.println("enter element: ");                 string element = bf.readline();                  system.out.println("enter data: ");                 string data = bf.readline();                 element em = d1.createelement(element);                 em.appendchild(d1.createtextnode(data));                  e1.appendchild(em);             }             transformerfactory tf = transformerfactory.newinstance();             transformer transformer = tf.newtransformer();             domsource source = new domsource(d1);              file file = new file("src\\xml\\copy.xml");             system.out.println(file);              if(!file.exists()){                 file.createnewfile();             }             outputstream outputstream = new fileoutputstream(file);             streamresult result = new streamresult(outputstream);             transformer.transform(source, result);             outputstream.close();          }catch (exception e) {             // todo: handle exception             e.printstacktrace();             system.out.println("file not created");         } 

this code works well. have string such:

string xmlrecords = "<data><terminal_id>1000099999</terminal_id><merchant_id>10004444</merchant_id><merchant_info>mc donald's - abdoun</merchant_info></data>"; 

i want create .xml file xmlrecords variable. how do this?

you can parse xml string document this:

string xmlrecords = "<data><terminal_id>1000099999</terminal_id><merchant_id>10004444</merchant_id><merchant_info>mc donald's - abdoun</merchant_info></data>";  documentbuilderfactory factory = documentbuilderfactory.newinstance(); documentbuilder builder = factory.newdocumentbuilder(); document d1 = builder.parse(new inputsource(new stringreader(xmlrecords))); 

you can keep file writing part mentioned in question, replace creation of document instance above code.
