I am trying to convert this xml into csv I have tried some thing like this but I am not getting any logic to convert data to csv format

       try {
            var file : File = new File(dw.io.File.IMPEX + '/src/weather.csv');
            var fileWriter : FileWriter = new FileWriter(file, 'UTF-8');
            var csw : CSVStreamWriter = new CSVStreamWriter(fileWriter);
            csw.writeNext(//here I want array of string data );
            csw.writeEndDocument();
            csw.close();
            fileWriter.close();
        }
        catch(e) {
            return PIPELET_ERROR;
        }

But I don't know how I can convert xml data into strings of array

See #7950252 for a way to parse XML into JavaScript objects. Then you pick out the bits you want to put in your array. – Elysium

As you're using server-side JavaScript, moreover DemandwareScript, check XMLStreamReader class and E4X syntax. https://en.m.wikipedia.org/wiki/ECMAScript_for_XML E4X is EcmaScript For Xml, a proprietary syntax which is used for XML DOM access in Demandware. You would need one more File object for reading the XML file.

Also your XML file is not "flat", so you would need to define which XML elements go where in the CSV.
