How to fix 'Errors were reported during stylesheet compilation' in XSLT?

Question

I have this SaxonApiException when I run my XSLT code on https://xslttest.appspot.com/. It return this error :

net.sf.saxon.s9api.SaxonApiException:

Answer 1

1. There should be <xsl:otherwise> instead of <otherwise>

2. <xsl:sort> should be in <xsl:for-each> .(You have ended the loop in same line)

3. To loop over Address, you will need xpath ../../Addresses/Address. Because at that time <Wage> is being processed. ( ../ will bring you up one level to parent node.)
