Many thanks to Martin Honnen for his response below. I add more comments below
(suspected bug in Saxon).

If I start with an input XML document that contains mixed text with <word>
elements like this:
… this is just <word correction=“too”>to</word> funny
I’d like to write an XSLT stylesheet that yields as output
… this is just <word origerror=“to”>too</word> funny
So in the output I effectively want (in the same <word> element) to
1. Set the value of a new attribute to the original text() value, and
2. Reset the text() value to be the value of the original @correction
attribute
I’ve tried many variants of the following, so far without success. I’m
using SaxonHE9-7-0-6J;
it runs, but the results are not as expected/hoped.
I’ve tried matching the text() in a separate template, but I can’t seem to
reference the attribute values of the parent node (i.e., <word>) of the
text() and the parent node’s attributes. E.g, the following doesn’t work
for me, failing somehow in the
select=“../@correction” reference.
<xsl:template match=“word[@correction]/text()”>
<xsl:value-of select=“../@correction”/>
</xsl:template>
You can use
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="word[@correction]/text()">
<xsl:value-of select="../@correction"/>
</xsl:template>
<xsl:template match="word/@correction">
<xsl:attribute name="origerror" select=".."/>
</xsl:template>
Your solution looks perfect and appears to work perfectly for ASCII-based XML
input examples like the following
<?xml version="1.0" encoding="UTF-8"?>
<foo>
<bar>this is just <word correction="too">to</word> funny</bar>
</foo>
yielding the correct/desired output
<?xml version="1.0" encoding="UTF-8"?>
<foo>
<bar>this is just <word origerror="to">too</word> funny</bar>
</foo>
I now see that some of my own attempts also worked, on the same ASCII-based
example.
***** Suspected bug involving supplementary characters *****
But my real task involves an input XML document, in UTF-8 encoding, that
consists of Deseret Alphabet characters, which are encoded in the supplementary
area. In such a case, the resulting text content in the <word> element, copied
from an original attribute value, is corrupted. I saw such corruption in my
own attempts, and couldn’t understand what was happening.
Using the following input document (the Deseret Alphabet characters may not
display correctly for you)
<?xml version="1.0" encoding="UTF-8"?>
<foo>
<bar>𐑄𐐮𐑅 𐐮𐑆 𐐾𐐲𐑅𐐻 <word correction="𐐻𐐭">𐑂𐐯𐑉𐐮</word> 𐑁𐐲𐑌𐐮</bar>
</foo>
the output, using your script, is corrupted. The text() value in the output is
not the same as the original @correction value. Extra characters (just one in
this case) are inserted. The longer the original attribute value, the more
extra characters are inserted.
<?xml version="1.0" encoding="UTF-8"?>
<foo>
<bar>𐑄𐐮𐑅 𐐮𐑆 𐐾𐐲𐑅𐐻 <word origerror="𐑂𐐯𐑉𐐮">𐐻𐐻𐐭</word> 𐑁𐐲𐑌𐐮</bar>
</foo>
This kind of corruption is exactly what I was seeing using my own scripts,
leading me to bother the group.
I suspect a bug in the XSLT engine involving supplementary characters. Again,
I’m using SaxonHE9-7-0-6J.
What’s my next step?
Thanks,
Ken
