Reading XML with the XmlReader

NET Framework version 1. The text reader is used to walk through the nodes of the document, and then the validating reader gets into the game, validating each piece of XML based on the requested validation type.

The list of available constructors comprises the following overloads: If set to ExpandCharEntities, only character entities are expanded for example, '.

Any change entered directly to the underlying reader object can lead to unpredictable results. Indicates how entities are handled. Namespaces Indicates whether namespace support is requested.

Refer to 2 for more information about the base properties of XmlReader. This table does not include those properties defined in the XmlReader base class for which the XmlValidatingReader class simply mirrors the behavior of the underlying reader.

A DTD allows you to specify the children for each tag, their cardinality, their attributes, and a few other properties for both tags and attributes. NET Control to generate, create bar code image in. Determine if an element has content or is empty.

NET Framework provides a handy utility, named xsd.

In the meantime, let's analyze more closely the programming interface of such a class, starting with properties. A DTD follows a custom, non-XML syntax to define the set of valid tags, the attributes each tag can support, and the dependencies between tags.

XML documents must have a root node. Read and navigate attributes. XSDs include an all-encompassing type system composed of primitive and derived types. XmlReader is unlike the SAX model, which is a push model with the parser pushing events to the application.

The type and name of the current node. The return value can be cast to a more specific reader type, such as XmlTextReader. The dependency of validating readers on an existing text reader is particularly evident if you look at the class constructors. As mentioned, XDR is an early hybrid specification that never reached the status of a W3C recommendation.

Cardinality specifies the number of occurrences of each child element.

DTD was considered the cross-platform standard until a couple of years ago. Implementations of the XmlReader class extend the base class and vary in their design to support different scenario needs. Today, XSD is supported by almost all parsers on all platforms.

However, security constraints implemented in the. For more information, see http: The content of the current node. It can read a stream or a document, and it implements the namespace requirements outlined in the recommendation provided by the W3C located at www.

The class always works on top of an existing XML reader, and many methods and properties are simply mirrored. In the section "Under the Hood of the Validation Process," on page 89, we'll look more closely at the internal architecture of an XML validating reader.

The XmlReader class has methods to: Being an abstract base class enables you to customize your own type of reader or extend the current implementations of XmlTextReader, XmlValidatingReader, and XmlNodeReader classes. Each element is strongly typed. Use the XmlValidatingReader interface to manipulate the properties of the underlying reader.
