| | XPath - Wikipedia, the free encyclopedia |
 | | XPath syntax is designed to mimic URI (Uniform Resource Identifier) syntax or file name syntax. | | | Originally motivated by a desire to provide a common syntax and behavior model between XPointer and XSL, XPath has rapidly been adopted by developers as a small query language. | | | XPath expressions which might be used in an XSL context are: |

| | XPath - a Whatis.com definition |
| | XPath is a language that is used by and specified as part of both the Extensible Stylesheet Language Transformations (XSLT) and by XPointer (SML Pointer Language). | | | XPath is a language that describes a way to locate and process items in Extensible Markup Language (XML) documents by using an addressing syntax based on a path through the document's logical structure or hierarchy. | | | XPath also allows the programmer to deal with the document at a higher level of abstraction. |

| | XML Path Language (XPath) 2.0 |
| | XPath has a natural subset that can be used for matching (testing whether or not a node matches a pattern); this use of XPath is described in [XSLT 2.0]. | | | XPath is designed to be embedded in a host language such as [XSLT 2.0] or [XQuery]. | | | In order for XPath to be well defined, the input XDM instance, the static context, and the dynamic context must be mutually consistent. |

| | Java Pro - XPath 2.0: The Donald Sutherland of XML |
| | XPath is also an integral part of the XML Query Language, although in that case it is somewhat secondary to the native FOR-LET-WHERE-RETURN (FLWR, pronounced "flower") form preferred in most of the XML Query use cases. | | | When you make a query in XPath 1.0, what you are doing is creating a set of pointers to the nodes in an existing XML tree, rather than creating new nodes themselves. | | | A big part of the reason for its underdog status is that XPath never appears by itself; instead, it always supports some other language. |

| | XPath Basics |
| | The easiest analogy for understanding the syntax of basic XPath is to think about your file system and the paths that you use to specify the location of files or folders within the file system. | | | In the case of querying XML using XPath expressions in.NET, you do this by adding prefix and namespace URI pairs to an XmlNamespaceManager instance, then associating that namespace manager with the expression you are evaluating. | | | They are vital to querying XML documents in.NET today, and are used by a number of related XML technologies that you may need now and in the future. |

| | The syntax for patterns is a subset of the syntax for [XPath] expressions. | | | A node matches a pattern if the node is a member of the result of evaluating the pattern as an expression with respect to some possible context; the possible contexts are those whose context node is the node being matched or one of its ancestors. | | | Predicates are true XPath expressions, and XPath is much more of a true language than patterns; for example, XPath expressions can return not only lists of nodes, but also Boolean, string, and numeric values. |
