Increasingly, however, XSLT processors use optimization techniques found in functional programming languages and database query languages, such as static rewriting of an expression tree (e.g., to move calculations out of loops), and lazy pipelined evaluation to reduce the memory footprint of intermediate results (and allow "early exit" when the ...
XSL began as an attempt to bring the functionality of DSSSL, particularly in the area of print and high-end typesetting, to XML.. In response to a submission from Arbortext, Inso, and Microsoft, [2] a W3C working group on XSL started operating in December 1997, with Sharon Adler and Steve Zilles as co-chairs, with James Clark acting as editor (and unofficially as chief designer), and Chris ...
The fact that XSLT 2.0 uses XML syntax makes it rather verbose in comparison to XQuery 1.0. However, many large applications take advantage of this capability by using XSLT to read, write, or modify stylesheets dynamically as part of a processing pipeline. The use of XML syntax also enables the use of XML-based tools for managing XSLT code.
This is a series of XSLT 1.0 processors. The current version, 6.5.5, is not undergoing further development aside from maintenance. The 6 series is only available for the Java programming language. The current development line, Saxon 12, implements the XSLT 3.0 and XQuery 3.1 specifications. Saxon 12 can process XSLT 1.0 and XSLT 2.0 stylesheets.
XSLT is a Turing complete language, while CSS is not; this demonstrates a degree of power and flexibility not found in CSS. Additionally, XSLT is capable of creating content, such as automatically creating a table of contents just from chapters in a book, or removing/selecting content, such as only generating a glossary from a book.
Streaming Transformations for XML (STX) is an XML transformation language intended as a high-speed, low memory consumption alternative to XSLT version 1.0 and 2.0. Current work on XSLT 3.0 includes Streaming capabilities.
libxslt is the XSLT C library developed for the GNOME project. It provides an implementation of XSLT 1.0, plus most of the EXSLT set of processor-portable extensions functions and some of Saxon's evaluate and expressions extensions. libxslt is based on libxml2, which it uses for XML parsing, tree manipulation and XPath support.
To show CDATA markup in the output, the XSLT stylesheet that contains the identity transform template (not the identity transform template itself) should make use of the xsl:output attribute called cdata-section-elements. cdata-section-elements specifies a list of the names of elements whose text node children should be output using CDATA sections.
