The process of checking to see if a XML document conforms to a schema is called validation, which is separate from XML's core concept of syntactic well-formedness.All XML documents must be well-formed, but it is not required that a document be valid unless the XML parser is "validating", in which case the document is also checked for conformance with its associated schema.
SAX (Simple API for XML) is an event-driven online algorithm for lexing and parsing XML documents, with an API developed by the XML-DEV mailing list. [1] SAX provides a mechanism for reading data from an XML document that is an alternative to that provided by the Document Object Model (DOM).
Element substitution techniques allow the substitution of new XML Schema elements, representing derived NIEM properties that can be used where the parent properties are expected. There are three XML Schema techniques that support the NIEM use of element substitutions: use of substitution groups; creation of abstract, type-less elements, and
The reverse process, to serialize an object as XML, is called marshalling. Approaches to data binding can be distinguished as follows: XML schema based: Based on an existing XML schema, classes that correspond to the schema are generated. Class based: Based on a set of classes to be serialized, a corresponding XML schema is generated.
VTD-XML's combination of high performance, low memory usage, and efficient XPath evaluation makes possible a new XML data binding approach based entirely on XPath. This approach's biggest benefit is it no longer requires XML schema, avoids needless object creation, and takes advantage of XML's inherent loose encoding. [22]
The application parses XML documents. Tainted data is allowed within the system identifier portion of the entity, within the document type definition (DTD). The XML processor is configured to validate and process the DTD. The XML processor is configured to resolve external entities within the DTD.
Transaction Processing over XML (TPoX) is a computing benchmark for XML database systems. As a benchmark , TPoX is used for the performance testing of database management systems that are capable of storing, searching, modifying and retrieving XML data.
XQuery (XML Query) is an XML query language strongly rooted in XPath and XML Schema. It provides methods to access, manipulate and return XML, and is mainly conceived as a query language for XML databases. XML Signature defines syntax and processing rules for creating digital signatures on XML content.
