Opera -- displaying images in XML documents

[Jelks Cabaniss]

I asked this in two of the Opera newsgroups, but except for one person
who advised me to just use namespaced HTML elements in my XML, there
were no replies. Has anybody here successfully used Opera's CSS
extension "-o-replace" to display images in generic XML? See below:

---------
Opera has some nice (in theory) CSS extension to enable linking and
embedding in XML ...

http://www.opera.com/docs/specs/#xml-css-link

But the image embedding doesn't work. Take this snippet from a test
TEIlite document ...

....
<p>Here's a link to the <xref
url="EPU.http://emblems.let.uu.nl/emblems/html/">EPU</xref>.</p>

<p>Here's a picture: <figure
url="http://emblems.let.uu.nl/emblems/html/navicon/rd-small.gif"/></p>
....
With this CSS applied ...

....
p {
display: block;
}

xref { /* this works! */
-o-link: attr(url);
-o-link-source: current;
color: blue;
text-decoration: underline;
}

figure { /* this fails! */
-o-replace: attr(url);
}
....
The linking element (<xref>) works fine, but the image embedding
(<figure>) doesn't. What's wrong with "-o-replace"? I even tried
"content"[1] instead of "-o-replace", but it didn't work either.

I'm using Opera 7.54. Did -o-replace stop working somewhere along the
line, or am I using it incorrectly? What it does now is display the
actual URL string on the page, instead of the image that URL is
supposed to be pointing to. Does anybody here have images successfully
displaying in generic (non-XHTML) XML documents?

Thanks,

I have run some tests with different Opera 7 versions on Windows XP and
7.11 displays the image referenced, later version I have tested (7.20,
7.50, 8.00 Beta) do not display the image but the attribute value instead.

Thanks for confirming this, Martin.

Interestingly, nobody in the Opera newsgroups ever replied about this,
nor has their documentation at

http://www.opera.com/docs/specs/#xml-css-link

ever been updated to show this. It would be nice to have had
consistancy in the 7.x series, or at least some post-7.11 documentation
as to why the behavior of -o-replace had been changed.

Have you tried

-o-replace: url(attr("url"));

or

-o-replace: attr("url", url);?

I hadn't before, but I just tried them. Still no picture. In fact,
nothing. Plain attr(url) shows the attribute value (the string), but
quoting "url" -- and as in your second example -- ends up blank.

Is -o-replace working for use in XML documents? If so, what version of
Opera are you using?

Thanks,

Make that "for you", not "for use"...
