unzip zipfile data from a variable

[Harm Olthof]

Hello Tcl-ers,
Using [http::geturl] and subsequent [http::data] I obtained zipfile data from a REST webservice in a tcl variable.

I know that there's only one file (an xml file) in the zip file.
Is it possible to get the xml file contents from the tcl variable directly or should I first write the variable to a file on disk and use e.g vsf::zlib to get the contents of the xml file? I would like to process the xml data using tdom.
The zip file can get up to several hundreds of Mb's and I would like to prevent disk I/O.

Maybe memchan (or tcl::chan::memchan) is useful in your situation.

Regards,
Erik.

Thank, will try that out. tcl::chan::variable also looks interesting in this respect.
