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.
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.
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.
SimpleHtmlDom is a simple HTML document object model in C#, which can generate HTML string programmatically. APIs that expose DOM implementations: JAXP (Java API for XML Processing) is an API for accessing DOM providers; Lazarus (Free Pascal IDE) contains two variants of the DOM - with UTF-8 and ANSI format; Inspection tools:
To demonstrate specificity Inheritance Inheritance is a key feature in CSS; it relies on the ancestor-descendant relationship to operate. Inheritance is the mechanism by which properties are applied not only to a specified element but also to its descendants. Inheritance relies on the document tree, which is the hierarchy of XHTML elements in a page based on nesting. Descendant elements may ...
XPath also provides a range of functions, which XSLT itself further augments. XSLT 1.0 uses XPath 1.0, while XSLT 2.0 uses XPath 2.0. 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.
XPath expressions and functions can be used to calculate values by applying functions to the value of fields in the form, such as "concat(string(field1 + field2), "#;", field3)" (the concatenation of the sum of two fields, the string "#;", and the value of another field). XPath functions for manipulation of strings, simple mathematical ...
VTDNav (VTD Navigator) is the class that (1) encapsulates XML, VTD, and hierarchical info, (2) contains various navigation methods, (3) performs various comparisons between VTD records and strings, and (4) converts VTD records to primitive data types. AutoPilot is a class containing functions that perform node-level iteration and XPath.
