Thanks!
Strange that the files were not gzipped. I thought they would be when
saved as foo.xml.gz from DOLFIN, but apparently not.
Looks like a bug.
No it isn't. The xml library we use automagically unzip any zipped files.
When we save zip files we do it by explicitly writing the strings to
file. We need to provide a proper zip algorithm.
boost provide such frameworks with its ostream library. I is quite neat,
but of course it makes heavy use of templates. I used it in a previous
version of TriTetMesh, but abandoned it because I could not figure out
template related stuff. It should be quite straight forward for a C++
Guru to include for our xml files.
I looked at Boost for the compressed .vtu files, and it was horrible and
incomplete. Instead, I used zlib to compress parts of the .vtu files. It
was pretty easy, so it should be easy to compress entire files.
