Hello Reinhard, We currently have a compression mechanism in place that allows third party users to turn compression on, including various levels of compression + strategies etc... The problem we are finding to be specific is that the process of converting numbers (especially floats) into strings (and vice-versa) is extremely expensive. This is a known issue with Java, but as a lot of the work that our clients do involves the tranmission of numerical data, this results in a lot of "lost time". I guess my question was aimed at a level further up from the solution of embedding BinHex64 binary data into an XML file. Instead of inserting just floats etc.. as BinHex64, why not the whole structure.
I haven't looked into it, but I also wonder if a DOM object created in XERCES-J would be compatible with a XERCES DOM object for XERCES C/C++?

Is the problem the time it takes to convert the internal DOM to an XML file or the time it takes to send the XML text data over the network? For the latter one I would try to compress the data, which should be quite effective since it's only text.
