JSONiq [11] is a query and transformation language for JSON. XPath 3.1 [12] is an expression language that allows the processing of values conforming to the XDM [13] data model. The version 3.1 of XPath supports JSON as well as XML. jq is like sed for JSON data – it can be used to slice and filter and map and transform structured data.
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.
XSLT 3.0 will work with either XPath 3.0 or 3.1. In the case of 1.0 and 2.0, the XSLT and XPath specifications were published on the same date. With 3.0, however, they were no longer synchronized; XPath 3.0 became a Recommendation in April 2014, followed by XPath 3.1 in February 2017; XSLT 3.0 followed in June 2017.
XMLSpy 2007 added increased XPath capabilities, including better integration with Microsoft Word. [9] In 2008 XMLSpy was the gold recipient in the Development Platform category by SQL Server Pro. [10] In 2009 XMLSpy was named the Editors' Best Best Development Tool's Silver Award recipient by Windows IT Pro Magazine. [11]
XQuery (XML Query) is a query and functional programming language that queries and transforms collections of structured and unstructured data, usually in the form of XML, text and with vendor-specific extensions for other data formats (JSON, binary, etc.).
The XQuery and XPath Data Model (XDM) is the data model shared by the XPath 2.0, XSLT 2.0, XQuery, and XForms programming languages. It is defined in a W3C recommendation . [ 1 ] Originally, it was based on the XPath 1.0 data model which in turn is based on the XML Information Set .
As of 2021 the current version (10.6) conforms with the W3C Recommendations for XSLT 3.0, XPath 3.1, and XQuery 3.1. The Saxon source code is written in Java. During 2005-6, M. David Peterson and others demonstrated that Saxon could be cross-compiled to run on .NET using the IKVM.NET cross-compiler, launching Saxon.NET as a separate product ...
