J2me: how to parse an array of bytes in xml and then read and display specific data from this XML

Question

I use the ASP.NET web API method, which returns the data in xml format. Everything was fine until I had to parse the byte array obtained from openInputStream. Everyone says that they use this or that library, but, unfortunately, there is not much information, and the only worthy example I found is an outdated library called KXML, in which the author reads a physical document (obviously not my case) . Personally, I wanted to use KXML2, but this moment I am desperate and open to the very first solution, which allows me to read XML as easily as possible.

Here is the code I use to use the Web API method:

HttpConnection connection = null; InputStream is = null; final ByteArrayOutputStream bos = new ByteArrayOutputStream(); byte[] response = null; try { connection = (HttpConnection)Connector.open("http://myminimarket/api/customers/GetCustomers", Connector.READ); connection.setRequestMethod(HttpConnection.GET); connection.setRequestProperty("User-Agent", "Profile/MIDP-2.0 Configuration/CLDC-1.1"); if (connection.getResponseCode() == HttpConnection.HTTP_OK) { is = connection.openInputStream(); if (is != null) { int ch = -1; while ((ch = is.read()) != -1) { bos.write(ch); } response = bos.toByteArray(); } } } catch (Exception e) { e.printStackTrace(); } finally { try { if (bos != null) { bos.close(); } if (is != null) { is.close(); is = null; } if (connection != null) { connection.close(); connection = null; } } catch (Exception e2) { e2.printStackTrace(); } } 

And here is a sample XML result that I got from the GetCustomers method:

 <ArrayOfCustomer xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/WSWebAPI.Helpers"> <Customer> <codigoCli>30</codigoCli> <direccion>MCDO.

With these details, I would like to find a way to display something like this:

Client number 1:

codigoCli: 30

direccion: MCDO. SAN MARTIN PSTO. Number 06

nroID: 26626315

nroTelef: 365548

Client number 2:

I really hope that you can understand my situation as a .net developer, it really disappoints, they don’t find much information on a topic like this.

Any help you can provide would be greatly appreciated.

Thanks in advance.

Answer 1

You can use setInput (new ByteArrayInputStream (response), null / null for auto-detection, or specify the correct type of id /) encoding to parse the xml response. Or what is the problem with kxml2?
