Declarative Processing of Semistructured Web Data
In order to give application programs access to data stored in the web in semi-structured formats, in particular, in XML format, the authors propose a Domain-Specific Language (DSL) for declarative processing such data. Their language is embedded in the functional logic programming language Curry and offers powerful matching constructs that enable a declarative description of accessing and transforming XML data. They exploit advanced features of functional logic programming to provide a high-level and maintainable implementation of their language. Actually, this paper contains the complete code of their implementation so that the source text of this paper is an executable implementation of their embedded DSL.
