Hi Gilles,
Thanks, and <smile> I realise the unusual nature of this kludge. Hopefully,
the exclusivity of htdg-description will render it benign on all other
systems. I'll perhaps code a more robust solution if I can get this one
working first.
I spent a good portion of yesterday going through the code and had arrived
at pretty much the answer you provide: skip the call to encodeSGML()
However, after making the change, recompiling and executing rundig, htsearch
doesn't produce the results either of us expected. EG: Here's a sample
htdig-description META from my site
(http://www.greymattermedia.com/algtr001.htm)
<META NAME="htdig-description"
CONTENT='<IMG align=left width=192 height=192
SRC="http://www.greymattermedia.com/images/algtrs01.jpg" align=TEXTTOP
HSPACE=5 VSPACE=0 BORDER=0 ALT="Alligator Creek National Park">Water and
time collaborate to create a fanciful waterway. :: Alligator Creek National
Park, Queensland, Australia; The Natural Order Katrin'>
And here's the search result template for the page generated by htsearch
(http://www.greymattermedia.com/cgi-bin/htsearch?config=htdig&restrict=&excl
ude=&words=alligator)
<dl><dt><strong><a
href="http://www.greymattermedia.com/algtr001.htm">Suitable for Framing :: -
Respite at Alligator Creek -</a></strong><img src="/htdig/star.gif"
alt="*"><img src="/htdig/star.gif" alt="*"><img src="/htdig/star.gif"
alt="*"><img src="/htdig/star.gif" alt="*">
</dt><dd><IMG align=left width=192 height=192
SRC="http://www.greymattermedia.com/images/algtrs01.jpg"
align=TEXTTOP HSPACE=5 VSPACE=0 BORDER=0
ALT="<strong>Alligator</strong> Creek National Park"><br>
<i><a
href="http://www.greymattermedia.com/algtr001.htm">http://www.greymattermedi
a.com/algtr001.htm</a></i>
<font size="-1">02/19/01, 15400 bytes</font>
</dd></dl>
This behaviour is odd on two levels:
1) It not only replaces the <, > and " characters with entities
2) It also truncates the text following the IMG tag in the original
htdig-description
What's really odd is that even if, for some reason, I messed up and somehow
encodeSGML() is still getting called, that routine wouldn't be truncating
the text. Something else is going on.
I suspect there's a call made during the course of rundig that is altering
the description string, or I've missed something in HTML.cc that's doing it.
Not that I've been able to find it.
Cheers,
Patrick.
