XML validation is the process of checking a document written in XML (eXtensible Markup Language) to confirm that it is both well-formed and also "valid" in that it follows a defined structure. A well-formed document follows the basic syntactic rules of XML, which are the same for all XML documents. [ 1 ]
However the XML and HTML standards restrict the usable code points to a set of valid values, which is a subset of UCS/Unicode code point values, that excludes all code points assigned to non-characters or to surrogates, and most code points assigned to C0 and C1 controls (with the exception of line separators and tabulations treated as white ...
Liquid XML Studio provides features for editing and validating XML documents. The GUI is a multi-document tabbed design and each document can be viewed in a text, graphical or split view. Document validation includes both checking for well formedness against the W3C XML standard and also checking validity against associated W3C XML Schema.
[1] [3] The editor has good performance on large XML documents and has real time XML schema validation. [1] The editor also features an HTML viewer for displaying XSLT transformation results and a built-in XML comparison tool. [6] The program's source code was made available on CodePlex on 20 April 2007, and moved to GitHub in April 2016. [7] [8]
The process of checking to see if a XML document conforms to a schema is called validation, which is separate from XML's core concept of syntactic well-formedness.All XML documents must be well-formed, but it is not required that a document be valid unless the XML parser is "validating", in which case the document is also checked for conformance with its associated schema.
In November 2008, the W3C released the validator.nu HTML5 engine and the ability to check documents for conformance to HTML5. [5] W3C also offers validation tools for web technologies other than HTML/XHTML, such as CSS, XML schemas, and MathML. [6]
XMLSpy was first released in 1999, [1] producing an integrated development environment for XML. [2] It is a licensed software product that uses key protection to prevent unlicensed usage. [ 3 ] Version 3.5 was released in 2000, allowing graphical input for editing diagrams and access to remote files.
XML Schema, published as a W3C recommendation in May 2001, [2] is one of several XML schema languages.It was the first separate schema language for XML to achieve Recommendation status by the W3C.
