XML parsers come in two flavors:
- non-validating: the parser does not check a document against
any DTD (Document Type Definition -- see later); it only checks that the
document is well-formed (that it is properly marked up according to
XML syntax rules)
- validating: in addition to checking well-formedness, the
parser verifies that the document conforms to a specific DTD (either
internal or external to the XML file being parsed).
You probably want to use a validating parser for most purposes.
Most XML parsers are free. The Internet Explorer, Firefox, and Opera
browsers now come with XML parsing support.
There are also several different XML parsing models, which we'll discuss
briefly.
