Validating xml scema

The reason is that XML software should be small, fast, and compatible.HTML browsers are allowed to display HTML documents with errors (like missing end tags). A "well formed" XML document is not the same as a "valid" XML document. In addition, it must conform to a document type definition.XML documents are validated by the Create method of the Xml Reader class. Schema namespace contains extension methods that make it easy to validate an XML tree against an XSD file when using LINQ to XML.

An individual schema or a set of schemas (as an Xml Schema Set) can be added to an Xml Schema Set by passing either one as a parameter to the Add method of Xml Schema Set.

Note that when validating a document the target namespace of the document must match the target namespace of the schema in the schema set. property of the Xml Reader Settings object is set to Schema to enforce validation of the XML document by the Create method of the Xml Reader object.

A Validation Event Handler is added to the Xml Reader Settings object to handle any Warning or Error events raised by errors found during the validation process of both the XML document and the schema.

Most document types are subject to constraints that cannot be expressed with XML Schema. Don't hesitate to send suggestions and comments to Christoph Schneegans ([email protected]).

This validator tries to check these as well, which makes its results much more applicable to real-world applications: namespaces in .

Errors in XML documents will stop your XML applications.The W3C XML specification states that a program should stop processing an XML document if it finds an error. This validator does not download any DTD or schema files, but relies on its own ones.You can validate XML documents by URL, by file upload or by direct input.Furthermore, you can validate fragments of XML documents.You can easily validate the page that is currently displayed in your browser with this bookmarklet. The BMEcat 2005 schemas have been adapted during my work at business Mart AG.
