Hi,
I have the exact same problem, except I'm not using the Writer but writing
myself the output using the following code:
case FHtmlParser.HtmlTag.TagID of
...
// All other HTML codes
else WriteLn(FHtmlParser.HtmlTag.GetCode(qtAlways));
end;
And I get the following piece of code for empty attributes for images:
'<img border="0" alt hspace="1" vspace="1" src="lib/find-replace.png">'
I hope there is something I can do about it as this generates error with
the epub ebook validation tools.
Thanks,
John.
