Validating xslt black dating send thread

Since patterns group together different rules, Schematron is designed so that rules are declared as children of the The name of the pattern will always be displayed in the output, regardless of whether the assertions fail or succeed.If the assertion fails, the output will also contain the content of the assertion element.For example, a simple content model can be written like this: "The In order to implement the path expressions used in the rules in Schematron, XPath is used with various extensions provided by XSLT.Since the path expressions are built on top of XPath and XSLT, it is also trivial to implement Schematron using XSLT, which is shown later in the section Schematron processing.

In general these processors are divided into two groups: XSLT-based and XPath-based processors.Each rule is then grouped into patterns, which are given a name that is displayed together with the error message (there is really more to patterns than just a grouping mechanism, but for this introduction this is sufficient).The following XML document contains a very simple content model that helps explain the three layers in the hierarchy: The bottom layer in the hierarchy is the assertions, which are used to specify the constraints that should be checked within a specific context of the XML instance document.In a Schematron schema, the typical element used to define assertions is If you are familiar with XPath, these assertions are easy to understand, but even for people with limited experience using XPath they are rather straightforward.The first assertion simply tests for the occurrence of an attribute Each of these assertions has a condition that is evaluated, but the assertion does not define where in the XML instance document this condition should be checked.Instead of having the context set to all By moving some of the logic from the assertion to the specification of the context, the complexity of the rule has been decreased.This technique is often very useful when writing Schematron schemas.It has already been mentioned that Schematron makes various assertions based on a specific context in a document.Both the assertions and the context make up two of the four layers in Schematron's fixed four-layer hierarchy: This introduction coves only three of these layers (patterns, rules and assertions); these are most important for using embedded Schematron rules in RELAX NG.The Schematron schema language differs from most other XML schema languages in that it is a rule-based language that uses path expressions instead of grammars.This means that instead of creating a grammar for an XML document, a Schematron schema makes assertions applied to a specific context within the document.

  2. The Validate method validates the XML data in the XmlDocument against the schemas contained in the Schemas property. The Validate method performs infoset augmentation. Specifically, after successful validation, schema defaults are applied, text values are converted to atomic values as necessary, and type information is associated with.

  3. This also means that the functions in Schematron that are XSLT-specific. The Schematron schema is first turned into a validating XSLT stylesheet by transforming.
