Net xml validating reader
Perhaps the biggest innovation in the namespace, and the way in which you'll typically interact with XML documents, is through the use of a stream-based API analogous to the stream reading and writing performed on files discussed in Chapter 11.
At the core of this API are the classes, which provide read-only, forward-only cursor access to XML documents and an interface for writing out XML documents, respectively.
Visual WYSIWYG data design, rule entry wizards drag & drop dictionary components.
Will import, analyze / refactor from XML Schema / JSON.
As a result, many organizations use XML to pass documents and data both within the organization and between trading partners and vendors.
The ubiquitous nature of these exchanges means that sooner or later, developers will need to read and write XML documents, transform them with XSL, and validate them using XML schemas.
Canonical component dictionaries from schema sets, SQL, JSON, ERwin XSD, or spreadsheets.
The XML CAM templates (OASIS standard) store the exchange structure, content model, code lists, DBMappings, SQL lookups business rules (XPath).
Due to the ubiquitous nature of these exchanges, sooner or later developers will need to read and write XML documents, transform them with XSL, and validate them using XML schemas. Simply put, an entity reference allows an XML document to be compressed by defining an entity once in a document and referencing it multiple times like so: Public Sub Validate(By Val p File Name As String, By Val p Schema As String, _ By Val p Namespace As String) Dim o Read As Xml Text Reader Dim o Valid As Xml Validating Reader Try o Read = New Xml Text Reader(p File Name) o Valid = New Xml Validating Reader(o Read) Add Handler o Valid.
This section will discuss the support in the Services Framework for working with XML in these ways.
At the highest level, the classes used to manipulate XML in the Services Framework are included in the namespace collectively supports the W3C standards XML 1.0 and DTDs, XML namespaces ( XML schemas ( XPath expressions ( XSL transformations ( DOM Level 2 Core ( and SOAP 1.1. However, the Services Framework implementation includes better standards compliance and a simpler programming model (especially for streamed access) that should make life easier.
The implementation is in many ways a melding of the DOM and SAX and provides a simplified programming model like the DOM but in a stream-based architecture.
The programming model is simplified because it is a pull rather than a push model.
