Hi, Luca.

This is very likely a msxml3 bug, you could try to 'winetricks msxml3 msxml6'
to confirm that.

I suspect the problem is in how libxml2 reports attribute values. Document has
the following for sheet name:

---
<sheet name="a &amp; b" sheetId="1" r:id="rId1"/>
---

and libxml2 has explicit check for '&' entity in xmlParseAttValueComplex():

---
if ((ctxt->replaceEntities == 0) &&
    (ent->content[0] == '&')) {
     buf[len++] = '&';
     buf[len++] = '#';
     buf[len++] = '3';
     buf[len++] = '8';
     buf[len++] = ';';
} else {
     buf[len++] = ent->content[0];
}
---

meaning that for parsed entity reference that represents '&' it does
substitution that results in attribute value you got in Excel.

I'll take a look what could be done there.
