as an underlying format for application data model more preferable.
This chapter describes various performance tricks that allowed the author to write a very high-performing parser in C : pugixml.
But from the functionality point of view, it provides less functions which mean that the users themselves have to take care of more, such as creating their own data structures. I think the answer really depends on the characteristics of your application. ): Assume that an instructor has an XML document containing all the personal information of the students as well as the points his students made in his class, and he is now assigning final grades for the students using an application.
What he wants to produce, is a list with the SSN and the grades.
While the techniques were used for an parser, most of them can be applied to parsers of other formats or even unrelated software (e.g., memory management algorithms are widely applicable beyond parsers).
By contrast, however, an event-based API provides interfaces on handlers.It defines the document structure with a list of legal elements and attributes.A DTD can be declared inline inside an XML document, or as an external reference., newer XML namespace-aware schema languages (such as W3C XML Schema and ISO RELAX NG) have largely superseded DTDs.Even a non-validating parser has to do some relatively resource-intensive validation work.When performance is the primary goal, a compromise must be reached between performance and conformance.
There are four handler interfaces, Content Handler interface, DTDHandler interface, Entity Resolver interface and Error Handler interface.
