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.
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.
Compared to XPath 2.0, XPath 3.0 adds the following new features: . Inline function expressions Anonymous functions can be created in an expression context. For example, the expression function ($ a as xs:double, $ b as xs:double) as xs:double {$ a * $ b} creates a function that returns the product of its two arguments.
Jakarta XML Binding (JAXB) — formerly Java Architecture for XML Binding (this was its official Sun name, even though it is an API, see ) StAX (Streaming XML processing) — compatible with JDK 1.4 and above, included in JDK 1.6; Only the Java API for XML Processing (JAXP) is a required API in Enterprise Java Beans Specification 1.3.
XMLStarlet is a set of command line utilities (toolkit) to query, transform, validate, and edit XML documents and files using a simple set of shell commands in a way similar to how it is done with UNIX grep, sed, awk, diff, patch, join, etc commands.
Microsoft XML Core Services (MSXML) are set of services that allow applications written in JScript, VBScript, and Microsoft development tools to build Windows-native XML-based applications. It supports XML 1.0, DOM , SAX , an XSLT 1.0 processor, XML schema support including XSD and XDR , as well as other XML-related technologies.
The standard for querying XML data per W3C recommendation is XQuery; the latest version is XQuery 3.1. [13] XQuery includes XPath as a sub-language and XML itself is a valid sub-syntax of XQuery. In addition to XPath, some XML databases support XSLT as a method of transforming documents or query results retrieved from the database.
XPath, the XML Path Language, is a query language for selecting nodes from an XML document. XPath defines a syntax named XPath expressions that can query an XML document for one or more internal components (elements, attributes, etc.). XPath is widely used in other core-XML specifications and in programming libraries for accessing XML-encoded ...
