How to include javaScript file in xslt

Question

How can I include/import javaScript file/libary in xslt file.

Answer 1

If you need to use the javascript in the transformation (for example, it contains a set of extension functions that are called within the transformation), you need to put the javascript contents (at least that of one javascript file) in a separate XSLT stylesheet file, using the proper extension element (such as ) as the parent of the text-node that contains the javascript code.

Here is a very simple example, using any Microsoft XSLT processor (MSXML3/4/6, XslCompiledTransform or XslTransform):

file XSL-JS.xsl:

 
   function xml(nodelist) {
      return "A B C";
   }
 

File XSL-Main.xsl that is importing the javascript:

When the transformation, contained in the file XSL-Main.xsl is applied on any XML document (not used/ignored), the wanted, correct result is produced:

A B C

A completely different case is if you just want to generate with your XSLT application an HTML file that references a given Javascript file.

Then you include this in your XSLT code and generate this literally as part of the output:
