XPath 1.0 was published in 1999, XPath 2.0 in 2007 (with a second edition in 2010), XPath 3.0 in 2014, and XPath 3.1 in 2017. However, XPath 1.0 is still the version that is most widely available. [1] XPath 1.0 became a Recommendation on 16 November 1999 and is widely implemented and used, either on its own (called via an API from languages ...
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.
The "/" operator is generalized in XPath 2.0 to allow any kind of expression to be used as an operand: in XPath 1.0, the right-hand side was always an axis step. For example, a function call can be used on the right-hand side. The typing rules for the operator require that the result of the first operand is a sequence of nodes.
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 ...
XPath 3 is the latest version of the XML Path Language, a query language for selecting nodes in XML documents. It supersedes XPath 1.0 and XPath 2.0 . XPath 3.0 became a W3C Recommendation on 8 April 2014, while XPath 3.1 became a W3C Recommendation on 21 March 2017.
This is a series of XSLT 1.0 processors. The current version, 6.5.5, is not undergoing further development aside from maintenance. The 6 series is only available for the Java programming language. The current development line, Saxon 12, implements the XSLT 3.0 and XQuery 3.1 specifications. Saxon 12 can process XSLT 1.0 and XSLT 2.0 stylesheets.
It was difficult to see how to give XPath 2.0 proper coverage within that article, given that there are so many differences in the fundamental concepts of the two versions; the simplest approach seemed to be to create a new XPath 2.0 article, rename the existing article as XPath 1.0, and create a new XPath article to point to the two.
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.
