Here's the code
The type of quotes used on attribute values during serialization depends on the serializer. If you use the .toxml() method to serialize the document, you'll get double quotes, I believe. It won't pretty-print though. print doc.toxml() <?xml version="1.0"?><request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:noNameSpaceSchemaLocation="Handle.xsd"/> xml.dom.ext.Print and PrettyPrint haven't been updated in ages. Well, they've been updated, but only in 4Suite (where they manifest as Ft.Xml.Domlette.Print and PrettyPrint), not PyXML. In PyXML they're hard-coded to use single quotes as attribute delimiters. I asked on the list a while back if there was any interest in bringing 4Suite's Print/PrettyPrint implementation into PyXML and didn't get much response. It's the kind of thing where if I want to see it done, I have to submit patches. > I use to create this one: > > dom = xml.dom.minidom.getDOMImplementation() > doc = dom.createDocument(None, "request", None) > > #Get the document element > msg_elem = doc.documentElement > > #Create an xmlns attributes on the root element > msg_elem.setAttributeNS(EMPTY_NAMESPACE, "xmlns:xsi", > "http://www.w3.org/2001/XMLSchema-instance";) > msg_elem.setAttributeNS(EMPTY_NAMESPACE, "xsi:noNameSpaceSchemaLocation", > "Handle.xsd") This isn't related to your quoting problem, but you are using the wrong namespaces. Instead of EMPTY_NAMESPACE you need to do it like this: msg_elem.setAttributeNS(XMLNS_NAMESPACE, 'xmlns:xsi', 'http://www.w3.org/2001/XMLSchema-instance') msg_elem.setAttributeNS('http://www.w3.org/2001/XMLSchema-instance', 'xsi:noNameSpaceSchemaLocation','Handle.xsd') > 2.

Or is it possible to > correctly read out this xml file? A "file" in Python is any file-like object, basically anything with a .read() and maybe also .write() method for byte strings. This includes the sys.stdin, stdout, stderr streams. So to pretty-print to the screen, you could just do PrettyPrint(doc, sys.stdout) And to print to a buffer rather than an external file: f = cStringIO.StringIO() PrettyPrint(doc, f) To read from that buffer into a string, s: s = f.getvalue() Alternatively: f.reset() s = f.read() To read from an external file: f = open('yourfile', 'rb') s = f.read() f.close() Always be sure to call close() on your file-like objects when you're done reading or writing to them. (though not really necessary on sys.stdin, stdout, stderr) I don't know what web API you're using, but if you have access to an object representing the HTTP request, it might have a method that reads from a stream, in which case you could do something like PrettyPrint(doc, request.stream) to print directly to into the request object.
