When the dictionary contains an element type that is not supported by this method, it returns the EE_FAIL error.
var dictionary = shell.serviceManager.basics.dictionary; dictionary.setValueForKey("Hello World", "name"); dictionary.setValueForKey(false, "isVisible"); var users = shell.serviceManager.basics.array; users.addValue("john"); users.addValue("tom"); dictionary.setValueForKey(users, "users"); dictionary.setValueForKey(400, "width"); var xmlStream = shell.serviceManager.basics.memoryStream; dictionary.toXML(xmlStream); xmlStream.close(); /*The resulting XML in the stream will look like this: <dictionary> <string key="name">Hello World</string> <bool key="isVisible">false</bool> <compound key="users"> <array> <string>john</string> <string>tom</string> </array> </compound> <int32 key="width">400</int32> </dictionary> */
