>Summary: XQ: printing special characters in comment nodes
Initial Comment:
Hi,
I found MonetDB/XQuery has trouble with the printing of a document/node
sequence when special characters occur in comment nodes.
For example, the attached test.xml looks like this
<?xml version="1.0" encoding="utf-8"?>
<test>
<!--
<comment/>
abc
& def
-->
</test>
Looking at the tables in the DB I see the comment string is correctly parsed
(including the &), but when the node is printed output stops just before &, the
rest of the document/node/node sequence is not printed.
E.g.,
doc("..../test.xml")
gives the following output:
<?xml version="1.0" encoding="utf-8"?>
<test>
<!--
<comment/>
abc
The problem only occurs when a line *starts* with '&'

I think its not Mapi but the serialiser

it goes wrong in multiple ways it seems:
RD 1184747690872: inserting prompt
TD 1184747698266: write final block: 17 bytes
TX 1184747698266: sdoc("test.xml")
RD 1184747698310: read final block: 189 bytes
RX 1184747698310: &1 0 1 1 1
% xquery.result # table_name
% xml # name
% varchar # type
% 60 # length
[ "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<test>\n\t<!--
<comment/>
abc
& def
-->\n</test>\n" ]
For some reason the newlines in the comment are not escaped. I can
imagine that in the = mode MapiClient uses the same sort of thing happens
therefore having the & as first char on the line or something.

Undoubtedly this has to do with the Mapi protocol where lines starting
with & have a meaning.
