Major improvements to XML parsing for perfect round-trip EXI encoding: - **Namespace-aware XML parsing**: Handle ns1:, ns2:, ns3:, ns4: prefixed tags - **Enhanced find_tag_content()**: Auto-detect namespaced and regular tags - **Improved find_tag_in_section()**: Process PhysicalValue tags with namespaces - **SessionID namespace support**: Parse both <SessionID> and <ns2:SessionID> - **Perfect round-trip encoding**: XML → EXI → XML with 100% binary accuracy Test results: ✅ test3.exi: 43 bytes - perfect decode/encode ✅ test4.xml: Perfect XML→EXI→XML round-trip ✅ test5.exi: 43 bytes - identical binary reconstruction ✅ All Unit values preserved as numbers (3=A, 4=V, 5=W, 2=s) ✅ EVErrorCode preserved as numbers (0 instead of NO_ERROR) The enhanced_exi_viewer now supports complete bidirectional EXI ↔ XML conversion with namespace-aware parsing. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

------------------------------------------------------------------------- * fix possible memory corruption bug ------------------------------------------------------------------------- CHANGES from version 0.9.3: ------------------------------------------------------------------------- * Support for 15118-2-2016 (ISO2) started besides 15118-2-2013 (ISO1) and DIN * fix eMAID fragment encoding/decoding support * internal coding updates * bug-fixes ------------------------------------------------------------------------- CHANGES from version 0.9.2: ------------------------------------------------------------------------- * resolves XML signature interoperability issue Note: To make use of xmldsig the following defines have to be set. in "xmldsigEXIDatatypes.h" #define DEPLOY_XMLDSIG_CODEC SUPPORT_YES #define DEPLOY_XMLDSIG_CODEC_FRAGMENT SUPPORT_YES in "v2gEXIDatatypes.h" #define DEPLOY_ISO_CODEC_FRAGMENT SUPPORT_YES Otherwise the code is turned off. ------------------------------------------------------------------------- CHANGES from version 0.9.1: ------------------------------------------------------------------------- * resolves bug with name clashes w.r.t. iso and din track * fixes issue with test code for init handshake * Note: OpenV2G 0.9.2 is essentially just a bug fixed version of OpenV2G 0.9.1 ------------------------------------------------------------------------- CHANGES from version 0.9: ------------------------------------------------------------------------- * includes support for DIN and hence interoperability with OpenV2G 0.7 (needs to be switched on though by #define DEPLOY_DIN_CODEC) * fixes bugs and warnings for Visual Studio * Note: OpenV2G 0.9.1 is a superset of previous versions v2g...c/h files support ISO track din...c/h files support DIN track ------------------------------------------------------------------------- CHANGES from version 0.8: ------------------------------------------------------------------------- * large code footprint reduction which resulted in a new API (please take a look at the example in src/test folder) * datatype differences w.r.t. arrays, strings, bytes, isUsed, and enum-naming * bug-fixes * Note: OpenV2G 0.8 and 0.9 are interoperable, meaning that one can generate streams with one and decode with the other or vice-versa ------------------------------------------------------------------------- CHANGES from version 0.7: ------------------------------------------------------------------------- * adaption of V2G schema changes (reflects the ISO/IEC 15118-2 FDIS status) * bug-fixes ------------------------------------------------------------------------- CHANGES from version 0.7: ------------------------------------------------------------------------- * adaption of V2G schema changes (reflects the ISO/IEC 15118-2 FDIS status) * bug-fixes ------------------------------------------------------------------------- CHANGES from version 0.6: ------------------------------------------------------------------------- * adaption of V2G schema changes (reflects the ISO/IEC 15118-2 DIS status and DIN 70121) * reduced memory usage * EXI decoder skips schema deviations according to EXI Profile * bug-fixes ------------------------------------------------------------------------- CHANGES from version 0.5: ------------------------------------------------------------------------- * adaption of V2G schema changes * application handshake protocol implementation * asynchronised communication * reduced memory usage * changed V2GTP byte order from little endian to big endian * bug-fixes * updated AC demo interaction between EV and EVSE, and * updated DC demo interaction between EV and EVSE ------------------------------------------------------------------------- CHANGES from version 0.4: ------------------------------------------------------------------------- * adaption of V2G schema changes * V2GTP implementation (replaces the DoIP implementation) * EXI default coder for the 15118 schema (replaces the strict mode of EXI) * AC demo interaction between PEV and EVSE, and * DC demo interaction between PEV and EVSE ------------------------------------------------------------------------- CHANGES from version 0.3.1: ------------------------------------------------------------------------- * adaption of V2G schema changes * supporting of DC messages * example program showing the message sequence of AC charging and DC charging * bug-fixes ------------------------------------------------------------------------- CHANGES from version 0.3: ------------------------------------------------------------------------- * Bug-fixes * reduced memory usage * some type changes in the EXI codec and V2G service: ** struct v2gService->struct EXIService in v2g_service.h ** size_t->uint16_t in v2g_serviceClientDataTransmitter.h and doIP.h * renaming of some enumeration values in v2g_serviceDataTypes.h ------------------------------------------------------------------------- CHANGES from version 0.2.2: ------------------------------------------------------------------------- * Bug-fixes * first DoIP implementation * V2G message error handling * adaption of V2G schema changes * code optimizations ------------------------------------------------------------------------- CHANGES from version 0.2.1: ------------------------------------------------------------------------- * Bug-fixes * adaption of V2G schema changes * some code optimizations ------------------------------------------------------------------------- CHANGES from version 0.2: ------------------------------------------------------------------------- * Bug-fixes * Fixed compiler warnings ------------------------------------------------------------------------- CHANGES from version 0.1: ------------------------------------------------------------------------- *
