Homomorphic XML Compressors?

Question

ASP.NET

Good afternoon. I'm trying to determine the format for transferring not small volumes of data. Some data needs to be handled by the bus, so xml is needed.
There is an option to put most of the data in the form of a binary in bace64 CDATA, but there are compressors that preserve the xml structure.
Tell me some kind of compressor for .net - preferably not handicraft development, because it is very important not to lose data
