Method Detail

toJSONArray

public static JSONArray toJSONArray(String string)
                             throws JSONException

Convert a well-formed (but not necessarily valid) XML string into a JSONArray using the JsonML transform. Each XML tag is represented as a JSONArray in which the first element is the tag name. If the tag has attributes, then the second element will be JSONObject containing the name/value pairs. If the tag contains children, then strings and JSONArrays will represent the child tags. Comments, prologs, DTDs, and <[ [ ]]> are ignored.

Parameters:

string - The source string.

Returns:

A JSONArray containing the structured signalData from the XML string.

Throws:

JSONException

toJSONArray

public static JSONArray toJSONArray(XMLTokener x)
                             throws JSONException

Convert a well-formed (but not necessarily valid) XML string into a JSONArray using the JsonML transform. Each XML tag is represented as a JSONArray in which the first element is the tag name. If the tag has attributes, then the second element will be JSONObject containing the name/value pairs. If the tag contains children, then strings and JSONArrays will represent the child content and tags. Comments, prologs, DTDs, and <[ [ ]]> are ignored.

Parameters:

x - An XMLTokener.

Returns:

A JSONArray containing the structured signalData from the XML string.

Throws:

JSONException

toJSONObject

public static JSONObject toJSONObject(XMLTokener x)
                               throws JSONException

Convert a well-formed (but not necessarily valid) XML string into a JSONObject using the JsonML transform. Each XML tag is represented as a JSONObject with a "tagName" property. If the tag has attributes, then the attributes will be in the JSONObject as properties. If the tag contains children, the object will have a "childNodes" property which will be an array of strings and JsonML JSONObjects. Comments, prologs, DTDs, and <[ [ ]]> are ignored.

Parameters:

x - An XMLTokener of the XML source text.

Returns:

A JSONObject containing the structured signalData from the XML string.

Throws:

JSONException

toJSONObject

public static JSONObject toJSONObject(String string)
                               throws JSONException

Convert a well-formed (but not necessarily valid) XML string into a JSONObject using the JsonML transform. Each XML tag is represented as a JSONObject with a "tagName" property. If the tag has attributes, then the attributes will be in the JSONObject as properties. If the tag contains children, the object will have a "childNodes" property which will be an array of strings and JsonML JSONObjects. Comments, prologs, DTDs, and <[ [ ]]> are ignored.

Parameters:

string - The XML source text.

Returns:

A JSONObject containing the structured signalData from the XML string.

Throws:

JSONException

toString

public static String toString(JSONArray ja)
                       throws JSONException

Reverse the JSONML transformation, making an XML text from a JSONArray.

Parameters:

ja - A JSONArray.

Returns:

An XML string.

Throws:

JSONException

toString

public static String toString(JSONObject jo)
                       throws JSONException

Reverse the JSONML transformation, making an XML text from a JSONObject. The JSONObject must contain a "tagName" property. If it has children, then it must have a "childNodes" property containing an array of objects. The other properties are attributes with string values.

Parameters:

jo - A JSONObject.

Returns:

An XML string.

Throws:

JSONException
