The event-driven model of SAX is useful for XML parsing, but it does have certain drawbacks. Virtually any kind of XML validation requires access to the document in full. . The most trivial example is that an attribute declared in the DTD to be of type IDREF, requires that there be only one element in the document that uses the same value for an ID attribu
RDFLib is a Python library for working with RDF, [2] a simple yet powerful language for representing information. This library contains parsers/serializers for almost all of the known RDF serializations, such as RDF/XML, Turtle, N-Triples, & JSON-LD, many of which are now supported in their updated form (e.g. Turtle 1.1).
XPath (XML Path Language) is an expression language designed to support the query or transformation of XML documents. It was defined by the World Wide Web Consortium (W3C) in 1999, [ 1 ] and can be used to compute values (e.g., strings , numbers, or Boolean values ) from the content of an XML document.
In computing, Open Data Protocol (OData) is an open protocol that allows the creation and consumption of queryable and interoperable Web service APIs in a standard way. Microsoft initiated OData in 2007. [1] Versions 1.0, 2.0, and 3.0 are released under the Microsoft Open Specification Promise.
The XML-RPC protocol was created in 1998 by Dave Winer of UserLand Software and Microsoft, [2] with Microsoft seeing the protocol as an essential part of scaling up its efforts in business-to-business e-commerce. [3] As new functionality was introduced, the standard evolved into what is now SOAP. [4]
XML is very well suited to parse data, deeply nested data and mixed content (such as text with embedded markup tags) XML is human readable whereas relational tables require expertise to access; Metadata is often available as XML; Semantic web data is available as RDF/XML; Provides a solution for Object-relational impedance mismatch [3]
Streaming API for XML (StAX) is an application programming interface to read and write XML documents, originating from the Java programming language community. Traditionally, XML APIs are either: DOM based - the entire document is read into memory as a tree structure for random access by the calling application
The XML Infoset specification provides a vocabulary to refer to the constructs within an XML document, but does not provide any guidance on how to access this information. A variety of APIs for accessing XML have been developed and used, and some have been standardized. Existing APIs for XML processing tend to fall into these categories:
