RE: [xml-dev] Best way to create an XML document

My preference is to use a SAX-like serializer driven by calls such as

attribute("a", "3")

This avoids the overhead of creating a tree in memory, while still giving
the benefits of having the system take care of matters such as escaping
special characters.

There are a number of such interfaces around depending on your environment,
e.g. the XmlWriter in .NET. I tend to use the internal one in Saxon, of
