This is the reason why (most of the) XML parser implementations do not support XML Namespaces by default, to handle the validation of XML documents with namespaces correctly it is therefore necessary to configure the underlying parsers to provide support for XML Namespaces.At one extreme, the DPH was assumed to be a web designer accustomed to writing CGI scripts without any formal training in programming, who was going to hack it together in a weekend.However, if the document is not well formed it will end with an error message.Because it is an event-based, non validating parser, Expat is fast and well suited for web applications.The parser is a software library (in Java it’s a class) that reads the XML document and checks it for well-formedness.
Configure Java APIs (SAX, DOM, dom4j, XOM) using JAXP 1.3 to validate XML Documents with DTD and Schema(s).) as defined below has been used in the code examples to validate the input document.
Because of the unique design of z/OS XML System Services, comparisons with other parsers using the SAX or DOM APIs should be judged in light of their different designs.
When an XML parser is only a single component of a much larger program, it cannot be large, slow, or resource-intensive.
In this chapter, we cover the rules of XML syntax that are stated or implied in the XML 1.0 Recommendation from the W3C.
A considerable amount of XML terminology is introduced, including discussions of parsing, well-formedness, and validation.object has been created, various attributes of the object can be set to handler functions.
