Another try with an older version:

$ java -cp "/path/to/lib/saxon9he.jar" net.sf.saxon.Query -qversion:3.0 -q:xquery.txt
Error on line 2 column 1 of xquery.txt:
  XPST0003 XQuery syntax error near #...rocessingml/2006/main"; copy $#:
    Unexpected token "copy" in path expression
Static error(s) in query

https://www.saxonica.com/html/documentation11/using-xquery/update.html clearly says: "Saxon-EE supports use of the update extensions to XQuery defined in the W3C Recommendation http://www.w3.org/TR/xquery-update-10/" and "Update is available only in Saxon-EE, and is supported only if explicitly requested". The error message about "java.lang.NoClassDefFoundError: org/xmlresolver/Resolver" suggests you don't have it on the classpath, normal installation of the zip from Github should have it on the classpath. — Martin Honnen, Apr 24 '23 at 05:57

Based on the Saxon Home Edition (HE) documentation, it supports just the XQuery 3.1 Minimal Conformance. And it doesn't include the following:

Optional features not provided: XQuery 3.1 Schema Aware, XQuery 3.1 Typed Data, XQuery 3.1 Static Typing, XQuery Update 1.0

And you need XQuery Update support for your task.

It seems that you would need to use Saxon PE or EE editions for your objectives.

Error handling could be maybe enhanced to explicitly explains that Saxon doesn't support `Update` – Gilles Quénot Apr 24 '23 at 00:44

If you need to use Saxon HE, I can show it to you how to achieve it via XSLT. – Yitzhak Khabinsky Apr 24 '23 at 00:45
No, thanks, not interested in XSLT. I focus on XQuery that days – Gilles Quénot Apr 24 '23 at 00:53

There are two separate problems here.

With Saxon-HE 11.4, as others have indicated, the problem is that Saxon-HE does not support XQuery Update.

With the newer version, you haven't got as far as that: here the problem is that org/xmlresolver/Resolver is not on your classpath. Saxon should find the resolver, even if it isn't on the classpath in its own right, provided it is in the same directory as the Saxon jar file itself.
