[xquery-talk] Can XQuery Update corrupt documents?

Hi all,

I'm struggling with an XQuery Update problem which is corrupting the file
I'm trying to update.  I've posted my code samples to
https://gist.github.com/joewiz/2369367de3babba30e0aad8c9beec893 - but
here's the core of the issue:

I'm working with a TEI document containing <ref> elements that I'm trying
to manipulate with XQuery Update. Specifically, I'm grabbing a page number
reference from the text node immediately following the <ref> element, and I
want to move the page number inside the <ref> element. (I'm actually trying
to do a few more things, but I've reduced the sample code to do just this,
because it illustrates the problem I'm facing.)

The problem is that the XQuery Update statement corrupts my file. The
resulting file has 0 bytes. When I comment out the XQuery Update statement
and uncomment the $test variable in the return expression, I get expected
results, so I think the logic is sound. I have a feeling that the problem
may have to do with line 25, where I add attributes to an element; when I
comment out this, the corruption doesn't occur. But I need the attributes
in that line. So I'm stumped. I've never encountered data corruption with
XQuery Update, so I really hope there's a solution.

I'm using Saxon-EE XQuery inside of oXygen 17.1, with Saxon's
options for XQuery 3.0 and XQuery Update enabled.

Many thanks for any suggestions,
