javascript - how to read & write external xml file in apache cordova? -

i creating android app. want use xml file store little amount of data short period of time.. able read xml using ajax.get() method file not able write xml.. please me so..

if want store little amount of data , using cordova, use , set local storage:

localstorage.setitem("lastname", "smith"); 

and

var agentsmith=localstorage.getitem("lastname"); 

as w3school says:

with local storage, web applications can store data locally within user's browser.

but if want use xml, do:

var v = new  xmlwriter();    v.writestartdocument(true);    v.writeelementstring('test','hello ');    v.writeattributestring('foo','bar');    v.writeenddocument();    console.log( v.flush() ); 

and obtain:

<?xml version="1.0" encoding="iso-8859-1" standalone="true" ?> <test foo="bar">hello world</test> 

like here create , modify xml file using javascript
