.NET-JSON-Transformer

A Visual Basic .NET implementation that converts a JSON literal into a .NET XDocument

To use the file simply add it to your project and call the JSON.Parse method.

Public Function Parse(ByVal source As String) As XDocument

Parameters

• source

  • Type: System.String
  • The JSON literal to be converted.

• Return Value

  • Type: System.Xml.Linq.XDocument
  • An XML representation of the JSON literal. If the JSON is not parsable, then the method returns Nothing.

• The parser ignores whitespace. So if the JSON literal is:

  {
    "string_key": [
      1,
      2,
      {
        "nested": true
      }
    ]
  }

Then it gets parsed as:

{"string_key":[1,2,{"nested":true}]}

• The returned XML is a 1-to-1 translation from the JSON. Using the same example as above, the resulting XML would be:

  <object>
    <array name="string_key">
      <number>1</number>
      <number>2</number>
      <object>
        <boolean name="nested">true</boolean>
      </object>
    </array>
  </object>
  

• The parser does not parse to the exact specifications of the EBNF found on http://www.json.org/ the following list the deviations in this parser:

  • Number: Checks if the number starts with either a positive sign or negative sign
  • Boolean: Checks for "true" or "false" based on case-insensitivity
  • Null: Checks for "null" based on case-insensitivity
  • String: Does not check for "\u" followed by 4 hexadecimal characters as an escape character

The following example demonstrates the Parse method.

Option Strict On
Public Module Module1
    Public Sub Main()
  	  Dim jsonLiteral As String = "{""key"": [1, 2, 3], ""nested"": {""object"": true}}"
  	  Console.WriteLine(JSON.Parse(jsonLiteral))
    End Sub
End Module
