Note: |

In the .NET Framework version 2.0 release, the recommended practice is to create XmlReader instances using the XmlReader..::.Create method. This allows you to take full advantage of the new features introduced in this release. For more information, see Creating XML Readers. |
This property can be changed at any time and takes effect on the next read operation.
Because the XmlTextReader does not have DTD information available to it, SignificantWhitepsace nodes are only returned within an xml:space='preserve' scope.
The following example reads an XML fragment.
