Validating a dtd bt home hub not updating
To highlight that the DTD has been used for the validation, the title attribute in the input document has a value which is not allowed according to this DTD.
When using this DTD to validate the input XML document, the following error gets reported: Before a document can be called XML and not csv, simple text or any other format, it needs to support the basic rules as defined by the XML Recommendation, when it adheres to these rules it is said to be Wellformed XML.
For validation to be possible, the XML document needs to be associated to a DTD or an XML schema. Up until this point, this lesson has concentrated on the non-validating parser.
This section examines the validating parser to find out what happens when you use it to parse the sample program.
Configure Java APIs (SAX, DOM, dom4j, XOM) using JAXP 1.3 to validate XML Documents with DTD and Schema(s).
Many Java XML APIs provide mechanisms to validate XML documents, the JAXP API can be used for most of these XML APIs but subtle configuration differences exists.
The W3C XML specification states that a program should stop processing an XML document if it finds an error.Blue wavy underlines show semantic errors based on DTD or schema validation.Each error has an associated entry in the error list.When editing an XML Schema file, the file located in the schema cache is used for validation.Any compilation errors are also shown with red wavy underlines.
