Parse Row Data which is in comment in xml

Hi,
here i am facing the problem with raw data parsing

then how can i get raw data

Sir,
Thank you for you valuable time, but the problem still exists.

I want data2 value from the PduToXml method, so what should i needto do to get the value

internal string PduToXml(GXDLMSTranslatorStructure xml,
GXByteBuffer value,
bool omitDeclaration,
bool omitNameSpace,
bool allowUnknownCommand,
