JSONPath in Delphi

For selecting multiple values, use XPath property:

Code: Select all

    var
      LObj: TBSObject;
      Matches: TBSValueArray;
    begin
      LObj := TBSObject.FromJSON(...);
      Matches := LObj.XPath['$.store.book[*].author'];
      LObj.Free;
    end;

For selecting first or single value, use XPathSingle property:

Code: Select all

    var
      LObj: TBSObject;
      LValue: TBSValue;
    begin
      LObj := TBSObject.FromJSON(...);
      LValue := LObj.XPathSingle['$.store.bicycle.color'];
      //LValue.AsString = "red"
      LObj.Free;
    end;
