This module contains XQuery functions and variables to perform XSLT transformations. All functions are preceded by the xslt:
prefix, which is linked to the http://www.basex.org/xslt
namespace. By default, this module relies on the internal XSLT 1.0 implementation of Java. If Saxon is found in the classpath, however, XSLT 2.0 is used.
Note that this module has been introduced with Version 6.7.1 of BaseX.
$xslt:processor
Signatures | $xslt:processor as xs:string |
Summary | This variable returns the name of the applied XSLT processor (currently: Java or Saxon ). |
$xslt:version
Signatures | $xslt:version as xs:string |
Summary | This variable returns the supported XSLT version (currently: 1.0 or 2.0 ). |
xslt:transform
Signatures | xslt:transform($input as item(), $stylesheet as item()) as node() xslt:transform($input as item(), $stylesheet as item(), $params as item()) as node()
|
Summary | Transforms the document specified by $input , using the XSLT template specified by $stylesheet , and returns the result as node() instance. $input and $stylesheet may be

Examples
Example 1: Basic XSL transformation with dummy document and without parameters
basic.xslt
<xsl:stylesheet version='1.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform'> <xsl:template match="/"> <result/> </xsl:template> </xsl:stylesheet>
Query:
xslt:transform(<dummy/>, 'basic.xslt')
Result:
<result/>
Example 2: XSLT transformation of an input document
Query:
let $in := <books> <book> <title>XSLT Programmer´s Reference</title> <author>Michael H. Kay</author> </book> <book> <title>XSLT</title> <author>Doug Tidwell</author> <author>Simon St. Laurent</author> <author>Robert Romano</author> </book> </books> let $style := <html xsl:version='2.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform' xmlns='http://www.w3.org/1999/xhtml'> <body> <h1>Books</h1> <ul> <xsl:for-each select='books/book'> <li> <b><xsl:apply-templates select='title'/></b>: <xsl:value-of select='string-join(author, ", ")'/> </li> </xsl:for-each> </ul> </body> </html> return xslt:transform($in, $style)
Result:
<html xmlns="http://www.w3.org/1999/xhtml"> <body> <h1>Books</h1> <ul> <li><b>XSLT Programmer´s Reference</b>: Michael H. Kay</li> <li><b>XSLT</b>: Doug Tidwell, Simon St. Laurent, Robert Romano</li> </ul> </body> </html>
