X

XForms:
An XML flexibility-driven application that can be used for generating dynamic web pages input and display screens. All this from XML documents.
XHTML:
A more restrictive but also more accurate and precise form of HTML.
XInclude:
An XML standard allowing inclusion of one XML document or script within another at execution time. XInclude effectively merges multiple XML files at run-time.
XLink:
XLink defines the standard by which web page hyperlinks are created from XML data in XML documents. Those XLink hyperlink standards are thus universally understandable for all XML documents.
XML:
See eXtensible Markup Language .
XML Data Type:
A data type that can store XML data as XML data, including the XML DOM and all XML capabilities and attributes. In other words, an XML data type stored in a relational database could have XML standards such as SQL/XML executed directly against that data type from within the relational database. Oracle Database and SQL Server Database allow use of and access to these data types (XMLType data types). DB2 Database also allows storage of XML data but is far more complex to use than XML data types used in Oracle and SQL Server.
XML Document:
A term used to describe a self-contained, well- formed set of XML data.
XML DOM:
XML Dynamic Object Model.
XML Fragment:
See Fragment .
XML Schema Definition:
XML Schemas are used to define logical structure onto XML data, much like defining a mapping between XML data and relational table structures (tables from a relational database). In addition, XML Schemas are also used in hand with other XML technologies, including XPath 2.0, XQuery, and even things such as SOAP.
XML Vocabulary:
Specific syntax in XML used to describe a specific application or industry. For example, MathML for representing mathematical expressions, functions, and whatever in XML.
XML-FO:
XML-FO or XML Format is used to format and beautify the output of XML for output display to the user . In reality, XML-FO is the formatting aspect of XSL. XSLT is the transformation aspect of XSL.
XPath:
XPath is used to navigate through XML documents based on an absolute path (from the root node) or a relative position of a node (from the currently active node) in an XML document.
XPath 1.0:
Version 1.0 of XPath, See XPath .
XPath 2.0:
A vastly improved and much more powerful successor to XPath 1.0. XPath 2.0 and XQuery 1.0 support all of the same functions and operators, and they share the same data model. XQuery queries of XML documents are built using XPath expressions. Seventy-five percent of XQuery functionality is actually XPath 2.0 functionality. Large parts of current XML standardization, including XQuery, XLink, XPointer, and XML Schema are all linked to, and built upon, the expressive parsing power of XPath 2.0 (integration).
XPath Expression:
XPath is all about expressions. An XPath expression is essentially a pattern used to search for matching patterns of elements, attributes, and values of both elements and attributes inside XML documents.
XPointer:
XPointer refines an XLink definition, allowing for pointing of hyperlinks to XML fragments within larger XML documents. See XLink .
XQuery:
XQuery is to XML as SQL is to relational databases. XQuery is used to read XML documents with the help of XPath expressions to select and filter data from XML data. XQuery is designed to query anything appearing as XML data, even XML data type structures (or otherwise ) stored in a database, as something like an XML data type. XQuery syntax is not written in XML (it is not an XML document).
XQuery 1.0:
The current version of XQuery. See XQuery and XPath 2.0 .
XQuery FLWOR:
FLWOR stands for For, Let, Where, Order By, and Return. The XQuery FLWOR statement is a form of a for loop. In programming parlance, a for loop allows repetitive processing of all the items in a collection of items. In other words, a for loop allows the same processing to be executed against every item in a collection.
XQueryX:
An XML document query language similar to XQuery, but written as XML scripting.
XSD:
See XML Schema Definition .
XSL:
See eXtensible Style Sheets .
XSL-FO:
The formatting aspect of XSL (as opposed to XSLT).
XSLT:
eXtensible Style Sheet Transformations. See eXtensible Style Sheets .
