Organized as tables, with one table per nesting depth level, LCs contain entries modeling an XML document's element hierarchy. An LC entry is a 64-bit integer encoding a pair of 32-bit values. The upper 32 bits identify the VTD record for the corresponding element.
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.
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.
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.
Selenium IDE is a complete integrated development environment (IDE) for Selenium tests. It is implemented as a Firefox Add-On and as a Chrome Extension.It allows for recording, editing and debugging of functional tests.
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 ...
