示例1: CopyXmlNode
//
// Copy a single XML node, attempting to preserve whitespace.
// A side effect of this method is to advance the reader to the next node.
//
// PERFORMANCE NOTE: this function is used at runtime to copy a configuration section,
// and at designtime to copy an entire XML document.
//
// At designtime, this function needs to be able to copy a <!DOCTYPE declaration.
// Copying a <!DOCTYPE declaration is expensive, because due to limitations of the
// XmlReader API, we must track the position of the writer to accurately format it.
// Tracking the position of the writer is expensive, as it requires examining every
// character that is written for newline characters, and maintaining the seek position
// of the underlying stream at each new line, which in turn requires a stream flush.
//
// This function must NEVER require tracking the writer position to copy the Xml nodes
// that are used in a configuration section.
//
internal bool CopyXmlNode(XmlUtilWriter utilWriter) {
//
// For nodes that have a closing string, such as "<element >"
// the XmlReader API does not give us the location of the closing string, e.g. ">".
// To correctly determine the location of the closing part, we advance the reader,
// determine the position of the next node, then work backwards to add whitespace
// and add the closing string.
//

// ^
// linePosition
//
lineNumber = _reader.LineNumber;
linePosition = _reader.LinePosition + _reader.Name.Length;
utilWriter.Write('<');
utilWriter.Write(_reader.Name);
//
// Note that there is no way to get spacing between attribute name and value
// For example:
//
// <elem attr="value" />
//
// is reported with the same position as
//
// <elem attr = "value" />
//
// The first example has no spaces around '=', the second example does.
//
while (_reader.MoveToNextAttribute()) {
// get line position of the attribute declaration
// <element attr="value"
// ^
// attrLinePosition
//

int attrLinePosition = _reader.LinePosition;
// Write the whitespace before the attribute
utilWriter.AppendRequiredWhiteSpace(lineNumber, linePosition, attrLineNumber, attrLinePosition);
// Write the attribute and value

charactersWritten += utilWriter.Write('=');
charactersWritten += utilWriter.AppendAttributeValue(_reader);
