Types Of Transformation language:-

1)XSLT transforms Language (Extensible Stylesheet Language Transformations):-
XSLT transforms an XML input document into a hierarchical result tree, which often is serialised as an XML instance (see figure).A transformation in the XSLT language is expressed as a well-formed XML document [XML] conforming to the Namespaces in XML Recommendation [XML Names], which may include both elements that are defined by XSLT and elements that are not defined by XSLT. XSLT-defined elements are distinguished by belonging to a specific XML namespace,which is referred to in this specification as the XSLT namespace.



2) XQuery Language
XQuery is a query language (with some programming language features) that is designed to query collections of XML data. It is semantically similar to SQL.
XQuery 1.0 was developed by the XML Query working group of the W3C. The work was closely coordinated with the development of XSLT 2.0 by the XSL Working Group; the two groups shared responsibility for XPath 2.0, which is a subset of XQuery 1.0. XQuery 1.0 became a W3C Recommendation on January 23, 2007.

3) STX
Streaming Transformations for XML (STX) is an XML transformation language intended as a high-speed, low memory consumption alternative to XSLT. STX is an XML standard for efficient processing of stream-based XML. As we will discover, XSLT is not well suited to stream based processing, and STX fills this niche.

4)FXT
FXT (Functional XML Transformation Tool) is an XML transformation language.

5) XDuce
XDuceis an XML transformation language.

6) CDuce
CDuce is an XML-oriented functional language, which extends XDuce in a few directions. It features XML regular expression types, XML regular expression patterns, XML iterators. CDuce is not strictly speaking an XML transformation language since it can be used for general-purpose programming.
CDuce conforms to basic standards: Unicode, XML, DTD, Namespaces are fully supported, XML Schema is partially supported.

7) HaXml
HaXml is a collection of utilities for parsing, filtering, transforming, and generating XML documents using Haskell. Its basic facilities include:

* a parser for XML,
* a separate error-correcting parser for HTML,
* an XML validator,
* pretty-printers for XML and HTML.

8) XML
An XML transformation language is a computer language designed specifically to transform an input XML document into an output XML document which satisfies some specific goal.

There are two special cases of transformation:

* XML to XML : the output document is an XML document.
* XML to Data : the output document is a byte stream.

9)FleXML
FleXML is an XML transformation language originally developed by Kristofer Rose. It allows a programmer to specify actions in C programming language or C++, and associate those actions with element definitions in an XML DTD. It is similar in philosophy to Yacc and the Lex programming tool in that it is a syntax-directed driver; one could establish the analogies Yacc:LR(1) grammar::Lex:Regular grammar::FleXML::XML.

The implementation is in Perl. A programmer supplied action file is input to FleXML; the output is a file suitable for input to Flex lexical analyser.
