Examples

// Dump dictionary content as XML
var
  dict: TIEDictionary;
begin
  dict := TIEDictionary.Create();
  dict.Insert('doublekey', 10.1);
  dict.Insert('integerkey', 100);
  dict.Insert('stringkey', 'hello');
  dict.Insert('bool_true', true);
  dict.Insert('bool_false', false);
  dict.Insert('dict', TIEDictionary.Create());
    dict.GetDictionary('dict').Insert('one', 1);
    dict.GetDictionary('dict').Insert('two', 'two');
  dict.Insert('list', TObjectList.Create());
    dict.GetList('list').Add( TIEDictionaryValueWideString.Create('mike') );
    dict.GetList('list').Add( TIEDictionaryValueWideString.Create('robert') );
    dict.GetList('list').Add( TIEDictionaryValueWideString.Create('john') );
    dict.GetList('list').Add( TIEDictionaryValueInteger.Create(2013) );

  memo1.Text := dict.Dump(ieplXML);

  dict.free;
end;


// Dump structure
dict := TIEDictionary.Create();
dict.Parse('{"string" : "string content", "myinteger": 1234, "mydouble": 123.456, "a_bool_true" : true, "a_bool_false" : false, "subdict" : {"name": "john", "surname" : "mad"}, "array": [1,2,3,4,"hello", {}, {"alfa":"beta"}, [9,10]] }');
memo1.Text := dict.Dump(ieplStructure);
dict.free;


// Parse all DictionaryEntries from XML file
// Download file from: www.imageen.com/files/UnitTestFiles/XML_TEST.xml

SAMPLE:

<?xml version="1.0" encoding="UTF-8"?>
<Proofreader>
 <Rules Language="EN">

     <Entry>add</Entry>
     <Entry>ancestor</Entry>

OUTPUT:
