Public Methods

public static String escape (String string)

Replace special characters with XML escapes:

 & (ampersand) is replaced by &amp;
 < (less than) is replaced by &lt;
 > (greater than) is replaced by &gt;
 " (double quote) is replaced by &quot;
 

Parameters
string The string to be escaped.
Returns
  • The escaped string.

public static void noSpace (String string)

Throw an exception if the string contains whitespace. Whitespace is not allowed in tagNames and attributes.

Throws
JSONException

public static Object stringToValue (String string)

Try to convert a string into a number, boolean, or null. If the string can't be converted, return the string. This is much less ambitious than JSONObject.stringToValue, especially because it does not attempt to convert plus forms, octal forms, hex forms, or E forms lacking decimal points.

Parameters
string A String.
Returns
  • A simple JSON value.

public static JSONObject toJSONObject (String string)

Convert a well-formed (but not necessarily valid) XML string into a JSONObject. Some information may be lost in this transformation because JSON is a data format and XML is a document format. XML uses elements, attributes, and content text, while JSON uses unordered collections of name/value pairs and arrays of values. JSON does not does not like to distinguish between elements and attributes. Sequences of similar elements are represented as JSONArrays. Content text may be placed in a "content" member. Comments, prologs, DTDs, and <[ [ ]]> are ignored.

Parameters
string The source string.
Returns
  • A JSONObject containing the structured data from the XML string.
Throws
JSONException

public static String toString (Object object, String tagName)

Convert a JSONObject into a well-formed, element-normal XML string.

Parameters
object A JSONObject.
tagName The optional name of the enclosing tag.
Returns
  • A string.
Throws
JSONException

public static String toString (Object object)

Convert a JSONObject into a well-formed, element-normal XML string.

Parameters
object A JSONObject.
Returns
  • A string.
Throws
JSONException
