XLinq Extension method

Defensive XLinq Query with XML Namespace

XPath

XPath is used to navigate through elements and attributes in an XML document. XPath is a major element in W3C's XSLT standard - and XQuery and XPointer are both built on XPath expressions.
XPath is a language for finding information in an XML document.

XSL-FO

XSL-FO is about formatting XML data for output. Styling is both about transforming and formatting information. When the World Wide Web Consortium (W3C) made their first XSL Working Draft, it contained the language syntax for both transforming and formatting XML documents.

Later, the Working Group at W3C split the original draft into separate Recommendations:

XSLT, a language for transforming XML documents
XSL or XSL-FO, a language for formatting XML documents
XPath, a language for navigating in XML documents

Example:

<?xml version="1.0" encoding="ISO-8859-1"?>

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">

<fo:layout-master-set>
<fo:simple-page-master master-name="A4">

</fo:simple-page-master>
</fo:layout-master-set>

<fo:page-sequence master-reference="A4">

</fo:page-sequence>

</fo:root>

XQuery

XQuery is to XML what SQL is to database tables. XQuery is designed to query XML data - not just XML files, but anything that can appear as XML, including databases.

XQuery Example

We will use the following XML document in the examples below.

<?xml version="1.0" encoding="ISO-8859-1"?>

XLink and XPointer

XLink defines a standard way of creating hyperlinks in XML documents. XPointer allows the hyperlinks to point to more specific parts in the XML document.

XML Schema

An XML Schema describes the structure of an XML document. XML Schema is an XML-based alternative to DTD.

XML DOM

The XML DOM defines a standard way for accessing and manipulating XML documents. The DOM presents an XML document as a tree-structure. The XML DOM defines a standard for accessing and manipulating XML.

XML DOM Parser

Most browsers have a built-in XML parser to read and manipulate XML. The parser converts XML into a JavaScript accessible object (the XML DOM).

XSLT

XSLT debugging in Visual Studio

XSL stands for EXtensible Stylesheet Language, and is a style sheet language for XML documents.
XSLT stands for XSL Transformations.

XML Fundamentals

XML (Extensible Markup Language) is a flexible way to create common information formats and share both the format and the data on the World Wide Web, intranets, and elsewhere. For example, computer makers might agree on a standard or common way to describe the information about a computer product (processor speed, memory size, and so forth) and then describe the product information format with XML. Such a standard way of describing data would enable a user to send an intelligent agent (a program) to each computer maker's Web site, gather data, and then make a valid comparison. XML can be used by any individual or group of individuals or companies that wants to share information in a consistent way.

XML, a formal recommendation from the World Wide Web Consortium (W3C), is similar to the language of today's Web pages, the Hypertext Markup Language (HTML). Both XML and HTML contain markup symbols to describe the contents of a page or file. HTML, however, describes the content of a Web page (mainly text and graphic images) only in terms of how it is to be displayed and interacted with. For example, the letter "p" placed within markup tags starts a new paragraph. XML describes the content in terms of what data is being described.

XML is "extensible" because, unlike HTML, the markup symbols are unlimited and self-defining. XML is actually a simpler and easier-to-use subset of the Standard Generalized Markup Language (SGML), the standard for how to create a document structure. It is expected that HTML and XML will be used together in many Web applications. XML markup, for example, may appear within an HTML page.

Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It is defined in the XML 1.0 Specification^[3] produced by the W3C, and several other related specifications,^[4] all free open standards.^[5]

The design goals of XML emphasize simplicity, generality, and usability over the Internet.^[6] It is a textual data format with strong support via Unicode for the languages of the world. Although the design of XML focuses on documents, it is widely used for the representation of arbitrary data structures, for example in web services.

Many application programming interfaces (APIs) have been developed to aid software developers with processing XML data, and several schema systems exist to aid in the definition of XML-based languages.

As of 2009, hundreds of document formats using XML syntax have been developed,^[7] including RSS, Atom, SOAP, and XHTML. XML-based formats have become the default for many office-productivity tools, including Microsoft Office (Office Open XML), OpenOffice.org and LibreOffice (OpenDocument), and Apple's iWork. XML has also been employed as the base language for communication protocols, such as XMPP.
