Parsing XML in Blackberry

Simple API for XML (SAX) was developed by the members of a public mailing list (XML-DEV).It gives an event based approach to XML parsing. It means that instead of going from node to node, it goes from event to event. SAX is an event driven interface. Events include XML tag, detecting errors etc, J2ME SAX - see BlackBerry/J2ME - SAX parse collection of objects with attributes

XML pull parser - It is optimal for applications that require fast and a small XML parser. It should be used when all the process has to be performed quickly and efficiently to input elements kXML - J2ME pull parser - see Better approach for XML Creation in Blackberry

Parsing XML with JSON

Blackberry standard for JSON parsing is JSON ME

No idea... JSON can be represented and transported as a XML, but not vice versa.

XML (Extensible Markup Language) is a set of rules for encoding documents electronically. It is defined in the XML 1.0 Specification produced by the W3C, and several other related specifications, all gratis open standards.

XML sample:

  
  This is Raphael's "Foligno" Madonna, painted in
    1511–1512.
  

JSON (an acronym for JavaScript Object Notation) is a lightweight text-based open standard designed for human-readable data interchange. It is derived from the JavaScript programming language for representing simple data structures and associative arrays, called objects (the “O” in “JSON”). Despite its relationship to JavaScript, it is language-independent, with parsers available for virtually every programming language.

JSON sample:

{
     "firstName": "John",
     "lastName": "Smith",
     "age": 25,
     "address": {
         "streetAddress": "21 2nd Street",
         "city": "New York",
         "state": "NY",
         "postalCode": "10021"
     },
     "phoneNumber": [
         { "type": "home", "number": "212 555-1234" },
         { "type": "fax", "number": "646 555-4567" }
     ]
 }

Basically if your XML is a strong equivalent of JSON, like:

  John
  Smith
  25
  

    21 2nd Street
    New York
    NY
    10021
  
  212 555-1234
  646 555-4567

there is a possibility to parse such XML with JSON.
