To generate an XML file using an XML serializer

Generating an XML file

• Create a few virtual SMS objects that exist in list
• Backup data is usually backed up to an SD card

Use StringBuffer to stitch strings

• append all the nodes of the XML file into SB object

   sb.append ("<?xml version= ' 1.0 ' encoding= ' utf-8 ' standalone= ' yes '?> ');//Add SMSS Start node sb.append (" <smss> " );.......

• Write SB into the output stream

  fos.write(sb.toString().getBytes());

To generate an XML file using an XML serializer

• Get the XML Serializer object

   xmlserializer xs = Xml.newserializer ();  

• Set the output stream to the serializer

  File file = new File(Environment.getExternalStorageDirectory(), "backupsms.xml");FileOutputStream fos = new FileOutputStream(file);//给序列化器指定好输出流xs.setOutput(fos, "utf-8");

• To start generating an XML file

  xs.startDocument("utf-8", true);xs.startTag(null, "smss");xs.endTag(null, "smss");   ......   xs.endDocument();
