Window popup in XML?
I apologize for the length of this, my first post here, but I have a
long story to
I am writing a page with mathematical content, and I have decided for
a variety of reasons to use MathML despite its incomplete support in
browsers. I am simultaneously trying to learn Macromedia Dreamweaver,
XML, CSS, and MathML so I don't know if this may be a newbie
but I haven't been able to find a solution to it. So far via a
books and web searches I've managed to find solutions to most of the
things I've wanted to do. But now I'm completely stumped.
Here's the basic sequence of problems and solutions:
1. Dreamweaver is set up to recognize XHTML, but I couldn't seem to
MathML examples into the XHTML and have them display (Firefox 3.0.1 is
my main test platform). Since the example pages at www.w3c.org/Math
seemed to be XML, I switched to XML, i.e put the following line at the
my file (there are other lines, which I'll get to in a minute).
I believe I also had to include an <?xml-stylesheet> tag and download
some XSL files, and also include this
(I think that last snippet came from W3C)
That is, I've done those things, but don't recall if that was the
set of actions to make MathML display. At any rate, it now displays
in the browser.
2. Dreamweaver is a developer program that has a split screen,
raw XML code in one window and an attempt to render the appearance
in another window. Changing from XHTML to XML broke the split screen.
Design Sciences has a page on working with Dreamweaver and MathML
Split screen still didn't work, i.e. Dreamweaver didn't recognize the
until I added a DOCTYPE tag and also renamed it to have an *.xht
That was sufficient to make split screen work again, though the <math>
are not recognized and math content does not appear correctly. Fine, I
live with that.
3. I started to realize pretty quickly that I was going to want to use
CSS. It took
me a while to figure out that I get only one <?xml-stylesheet> per
and that I use @import to combine them. But I did that. I wasn't sure
define a CSS file and import XSL (MathML comes with an XSL), but
seemed to complain when I did that.
So now my web page starts this way:
<?xml-stylesheet type="text/css" href="leverrier.css"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN"
and my CSS file starts this way:
All seems good.
4. Now I wanted some active content. My original HTML version of this
had popups that were implemented this way:
onClick="popup('images/lev58_4a.png', 'original');return false;">
This doesn't work in XML. I did some reading, and found that
(a) popping up new windows is frowned on now in polite society, and
(b) the hover trick using CSS to popup content when the mouse is
over some region of the page.
OK, fine. I implemented the hover trick. It works beautifully in my
But I'm beginning to think that I still want "click-to-show/click-to-
functionality. Ideally, I'd even want a checkbox that showed all
with a single click. The main driver for this is that I'd like to be
have the option of printing with the hidden content all showing.
And that brings me to...
change the class of an object on an XML page so that a different CSS
rule takes effect?
6. I'm also confused about the role of XSL. As I understand it, XSL
a page at browser access time. I could theoretically write rules so
browser receives HTML instead of XML. Then I could do all the
I want. But then my MathML would break, wouldn't it? That seems to
to be part of an XML page.
There's more, but that's enough for one post. Thanks for any insight
anyone can provide.

It depends on the browser. With Mozilla or Opera you can certainly use
the XHTML script element in XML or XHTML documents to use script.

I don't use MathML but I believe in the case of MathML the XSLT
stylesheet is used to cater for both Mozilla and IE. Mozilla should be
able to deal with your XML/MathML document just fine but with IE the
XSLT stylesheet is necessary to ensure IE renders any HTML and a plugin
renders the MathML.
