Text replacement - "syntaxhighlight" to "pre"
This [[Module Library|XQuery Module]] contains functions and variables to perform XSL transformations.
By default, this module uses Java’s XSLT 1.0 Xalan implementation to transform documents. XSLT 3.0 will be enabled is used if the [https://www.saxonica.com/ Saxon XSLT Processor] is found in the class path (e.g. by placing the library files in the [[Startup#Full Distributions|{{Code|lib/custom}} directory]]). A custom specific transformer can be specified by assigning a class classpath to the system property {{Code|javax.xml.transform.TransformerFactory}}, ewith the [https://docs.oracle.gcom/en/java/javase/11/tools/java. html -D flag] on the command line, or directly in Java:
<syntaxhighlight pre lang="java">
System.setProperty(
"javax.xml.transform.TransformerFactory",
...
ctx.close();
</syntaxhighlightpre>
=Conventions=
|- valign="top"
| '''Summary'''
|Returns the name of the applied XSLT processor, or the path to a custom implementation (currently: "Java", "Saxon EE", "Saxon PE", or "Saxon HE"). If a system property was assigned that points to an existing implementation other than Saxon, the classpath is returned instead.<br/>
|}
|- valign="top"
| '''Summary'''
|Returns the supported XSLT version (currently: "1.0" or , "3.0"). "Unknown" An empty string is returned if a custom classpath in the system property points to an existing implementation was chosenother than Saxon.<br/>

'''Query:'''
<syntaxhighlight pre lang="'xquery"'>
(: Outputs the result as html. :)

'''Example 3: XSL transformation with variable assignment'''
'''Query:'''
