XmlReader from another using XmlParserContex t and XmlReaderSettin gs

[Jen]

My main question: "How can I get a TextReader or Stream object from an
existing XmlReader?". Read on for more:

I have an existing XmlReader. Let's call it reader1. I'm creating
another reader, reader2, after creating new XmlReaderSettin gs and a new
XmlParserContex t.

// customContext and customSettings may or may not make use
reader1's properties
XmlParserContex t customContext = new XmlParserContex t(...);

XmlReaderSettin gs customSettings = new
XmlReaderSettin gs(...);

// This won't work, because reader1 isn't a TextReader,
Stream or URI.
XmlReader reader2 = XmlReader.Creat e(reader1,
customSettings, customContext);

I have to use an overload of XmlReader.Creat e() that takes both an
XmlReaderSettin gs and an XmlParserContex t as arguments, because they
cannot be set AFTER the XmlReader has been created. (Actually, Settings
can be set post-creation, but not the context, and customContext is
important.)

Here's the problem. XmlReader.Creat e() has _three_ overloads that take
both XmlParserContex t and XmlReaderSettin gs as arguments. But none of
these overloads takes an existing XmlReader. Here are the overloads:

1. XmlReader.Creat e (TextReader, XmlReaderSettin gs, XmlParserContex t)
2. XmlReader.Creat e (Stream, XmlReaderSettin gs, XmlParserContex t)
3. XmlReader.Creat e (String, XmlReaderSettin gs, XmlParserContex t) //
String is the URI

I believe that both (1) and (2) should work no matter what XmlReader
reader1 is. What's the easiest way to get a TextReader or Stream object
from an existing XmlReader? I don't think that there are easier ways to
do what I'm trying to do.
