13 \class TBufferXML
14 \ingroup IO
15 
16 Class for serializing/deserializing object to/from xml.
17 
18 It redefines most of TBuffer class function to convert simple types,
19 array of simple types and objects to/from xml.
20 Instead of writing a binary data it creates a set of xml structures as
21 nodes and attributes
22 TBufferXML class uses streaming mechanism, provided by ROOT system,
23 therefore most of ROOT and user classes can be stored to xml. There are
24 limitations for complex objects like TTree, which can not be yet converted to xml.
