I came across this extract from a table on a website:
<td ALIGN=CENTER VALIGN=CENTER WIDTH="120" HEIGHT="120"><a
href="66B27885.htm" "msover1('Pic1','thumbnails/MO66B27885.jpg');"
onMouseOut="msout1('Pic1','thumbnails/66B27885.jpg');"><img
SRC="thumbnails/66B27885.jpg" NAME="Pic1" BORDER=0 ></a></td>
Note the string beginning "msover1(", which seems to be an
attribute value without a name, so that makes it illegal HTML.
I haven't traced what Wget is actually doing when it encounters
this, but it doesn't treat "66B27885.htm" as a URL to be
downloaded.
I can't call this a bug, but is Wget doing the right thing by
ignoring the href altogether?
