When a base parameter is used in conjunction with the load_ext_dtd method the base parameter is ignored and the current directory is used as the base parameter.
I'll also walk you through some of the different scenarios and ways in which you can validate an XML document with an XSD schema programmatically (see Table 1). NET Framework 2.0 means you can perform XML data validation against a Document Type Definition (DTD) or an XML schema. XSD schema-based validation is the industry-accepted standard and will be the method of XML validation in this article.
You specify the validation settings as well as a Validation Event Handler method using the Xml Reader Settings object. I won't explain how to validate XML data using DTDs because those are not typically used outside legacy applications.
To be notified of validation errors in an XML document, the following must be true: It is helpful to start by defining the constants you will use when configuring the factory.
These are the same constants you define when using XML Schema for SAX parsing, and they are declared at the beginning of the Because JAXP-compliant parsers are not namespace-aware by default, it is necessary to set the property for schema validation to work.
Let's have a look at each together with some examples!
