Hello,
In the bugs@gnus.org list, I found a bug report which is
attached below. I don't know which of xml.el and nnrss.el is
wrong, but I found a strange behavior of xml.el.
(with-temp-buffer
(insert "<rss><![CDATA[ding]]></rss>")
(xml-parse-region (point-min) (point-max)))
=> ((rss nil "ding"))
(with-temp-buffer
(insert "<rss> <![CDATA[ding]]> </rss>")
(xml-parse-region (point-min) (point-max)))
=> ((rss nil " " 32 103 110 105 100))
The latter case seems to have returned a mirrored string as
characters:
(concat '(32 103 110 105 100))
=> " gnid"
Is it the intended behavior?
The problem Andrew M. Scott reported is not the same but similar
to this. The same behavior that xml-parse-region returns a
mirrored character sequence can be reproduced as follows:
cd /tmp
wget 'http://www.lockergnome.com/rss/news.php'
(with-temp-buffer
(insert-file-contents "/tmp/news.php")
(xml-parse-region (point-min) (point-max)))
Regards,
