ERR XTDE1425 while using Saxon - EE 11.4 On xml editor <Oxygen>

Question

I have the following lines of XSLT. When i try to transform my xml doc I receive the following:

Cannot find a 1-argument function named Q{urn:js}RoundOff()

I believe that there is no issue with the actual script just something that I need to change in the parser setting but I am not sure what to or where to change these settings.

  <![CDATA[
        function roundOff(hours) {
            return Math.round(hours * 100) / 100;
        }

        function getPeriodEndDate() {
            var today = new Date();
            var dayOfWeek = today.getDay();

            var tdate = new Date(today.getFullYear(), today.getMonth(), today.getDate());

            if (dayOfWeek === 0) {
                tdate.setDate(tdate.getDate() - 1);
            } else if (dayOfWeek === 1) {
                tdate.setDate(tdate.getDate() - 2);
            } else if (dayOfWeek === 2) {
                tdate.setDate(tdate.getDate() - 3);
            } else if (dayOfWeek === 3) {
                tdate.setDate(tdate.getDate() - 4);
            } else if (dayOfWeek === 4) {
                tdate.setDate(tdate.getDate() - 5);
            } else if (dayOfWeek === 5) {
                tdate.setDate(tdate.getDate() - 6);
            }

            var year = tdate.getFullYear();
            var month = tdate.getMonth() + 1;
            var day = tdate.getDate();

 

            if (month < 10) {
                month = '0' + month;
            }

            if (day < 10) {
                day = '0' + day;
            }

            return year + month + day;
        }
        ]]>

Assistance in editing or changing settings to allow the xslt to parse without errors 

Answer 1

Basically, you seem to expect to be able to implement extension functions for XSLT with J(ava)Script, that is not something that Saxon supports.

XSLT 2 and 3, and Saxon 11 is an XSLT 3 processor, have a rich XPath function library shared with XPath and XQuery, and furthermore allow you to declare and implement your own functions in pure XSLT/XPath.

So first check whether any of the functionality you need is available in https://www.w3.org/TR/xpath-functions-31/ (e.g. https://www.w3.org/TR/xpath-functions-31/#func-round), if not, implement it in XSLT/XPath using xsl:function: https://www.w3.org/TR/xslt-30/#stylesheet-functions

Answer 2

How about if you edit the transformation scenario you use in Oxygen and in the Transformer combo box you select one of the available MSXML processors instead of Saxon 11? https://www.oxygenxml.com/doc/ug-editor/topics/supported-XSLT-processors-x-2.html
