4.3 Moving On
I've now
shown you how to create XmlReader and
XmlWriter types to read one particular alternative
XML syntax, and how to use them in programs that think
they're reading and writing XML. You can think of
other applications; besides other alternative XML syntaxes, such as
YAML (Yet Another Markup Language) and James Clark's
Compact Syntax for RELAX NG, you could read data from other formats
completely unrelated to XML, such as CSV files, DBF files梕ven
databases and filesystems.
The knowledge of how to read and write XML to and from a variety of
physical and logical formats forms a good basis for
what's to follow. You'll see the
real power of XmlReader and
XmlWriter as they are combined with higher-level
XML functionality, starting with the Document Object Model.
