To a large extent, this does not affect or change the XML format at all. It's simply a different binary encoding of text data, and the text data is what is real. gzip knows nothing about XML and doesn't need to. 2 and 3 have to understand the XML document as an XML document to operate. That's a horse of a very different color. Consider what happens when parsing: if I have a gzipped document I first decode it into genuine XML and pass that into an XML parser. If I have an ASN.1 or Sosnoski format document, I use a different parser to decode the data directly into different objects. I neither create XML nor use an XML parser. -- Elliotte Rusty Harold elharo@m...
