How to remove zip compression from an XML file?

Question

I have an XML file format .zfo that is compressed using zip algorithm. I need to remove this compression from the file, so that it is in usable XML form.

How can I remove this compression, or decompress this XML file?

Its not like you might imagine i.e: .zip file containing an xml file. Instead the byte[] thats written to the file is zip compressed.

Thanks in advance.

Answer 1

Check out DotNetZip (http://www.codeplex.com/DotNetZip)--it probably does what you need (e.g., DeflateStream).

A zip file contains meta-data (file and directory structure) as well as the actually compressed data. It sounds like your file only has the compressed data. DotNetZip should be able to handle both.

Answer 2

That file isn't zip compressed at all. It appears to be some xml that's embedded in a certificate, issued by the Czech Post Office. The actual message looks to be encoded in some kind of base64 variant.

Call your post office.
