Add option to supress xml declaration (snippet-mode?)

[mmangione]

This module does a marvelous job of parsing and unparsing XML. However, when I unparse an ordereddict, I do not always need the version and encoding declaration.

For example, I am creating OrderedDicts from scratch and passing them to unparse. Since these are intended to be snippets instead of fully declared xml, I find myself manually postprocessing this to remove this declaration.

That's sounds like a nice feature, thanks. I will give it some thought as of how to implement it.

FYI I think I found a bug in this. If you pass something like so:

{
    "@name": "dbl-test",
    "description": "dbl-test",
    "recurring": {
        "hourly": {
            "at": "00"
        }
    },
    "type": "ip",
    "url": "http://192.168.1.6:8080/pa-dbl.txt"
}

It's not able to turn that into an "XML snippet" even when you have full_document=False.

@megahall I think it's not a bug: you cannot have a XML document with more than one root node. You should wrap that dict inside another dict with a single key:

{
    "root": {
        "@name": "dbl-test",
        "description": "dbl-test",
        "recurring": {
            "hourly": {
                "at": "00"
            }
        },
        "type": "ip",
        "url": "http://192.168.1.6:8080/pa-dbl.txt"
    }
}

Otherwise, what XML opening tag should the @name attribute belong to?
