Hi Bruce,
I don't understand, that code is in attribute content escaping, and
for me "{" and "}" are not escaped:
thinkpad2:~/XML -> cat ./tst.html
<html>
<body>
<img alt="{foo}"/>
</body>
</html>
thinkpad2:~/XML -> ./xmllint --html ./tst.html
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
"http://www.w3.org/TR/REC-html40/loose.dtd";>
<html>
<body>
<img alt="{foo}">
</body>
</html>
thinkpad2:~/XML ->
Please provide a reproducer with xmllint so I understand what is going on,
thanks,
Daniel
