Summary: XQ: problem with ampersand in attribute value
Initial Comment:
XML attribute values containing an ampersand give unexpected query results. In
the query response, the ampersand is apparently escaped twice into &
Example document aap.xml:
<aap>
This is ok: &
But this is bad: <noot q="&" />
</aap>
The XQuery doc("aap.xml") now returns:
<aap>
This is ok: &
But this is bad: <noot q="&#38;"/>
</aap>
Note that the problem only occurs with shredded documents, not with nodes
embedded in the XQuery. This suggests that the bug is somewhere in the shredder.
I enabled the debug statements in shred_start_element in shredder.c. This
showed that val at that point already contains "&" (I was expecting "&").

This seems to be a known bug in libxml software. I googled on this and
found for instance this discussion in a debian forum:
http://bugs.donarmstrong.com/cgi-bin/bugreport.cgi?bug=397395
I cannot do anything to fix it in the shredder. We just have to wait for
the fix in libxml2.
