Hi there!
I'm a beginning Python programmer, and I like it a lot already. Since my
Sharp Zaurus has a fairly complete Python environment including PyQT, I
thought it would be the perfect language for programming some nice
things on my Zaurus. The thing I really missed on the Z was a good
Jabber client. That's why I'm building my own. Things are going good,
and in a few nights I've been able to get a fairly decent though
under-featured client.
There is a small thing annoying me, though I'm trying to show the name
of the person saying something in color: red = someone else, blue = me.
This is an example of the text I'm adding to the QTextBrowser:
<font color='#0000ff' ><me></font>: hello world
It works like a charm on my PC, but on the Zaurus the text is all black.
Does anyone know how I can fix this?
~~~ brainwave flash ~~~
I just thought of something: what if the Z doesn't allow single quotes
around the "color" attribute? I gave it a try, and replaced the text
with:
<font color="#0000ff" ><me></font>: hello world
And it works!
Anyways, perhaps this will be picked up by others having the same
problem. I'll stick around in this group and try to soak up as many good
knowledge from people as I can ;-)
A bit about myself: I'm a 24 year old, studying Computer Sciences at the
University of Amsterdam, I'm Dutch (like Guido ;-)) and I currently live
in Amsterdam too. I've been a programmer for half my life now :)

The problem with the world is stupidity. Not saying there should be a
capital punishment for stupidity, but why don't we just take the
safety labels off of everything and let the problem solve itself? 12 3201 I just thought of something: what if the Z doesn't allow single quotes around the "color" attribute? I gave it a try, and replaced the text with:

Very fun stuff. Someday I hope to have a Zaurus or similar device to
toy with. Anyway, to actually be on topic, "proper" HTML (XHTML 1.0,
and maybe HTML 4.0? I don't recall...) requires double-quotes to be
used. Single quotes are illegal. So, the Qt version your Zaurus is
using must be a little more strict.

Are you certain about that? It seems very unlikely that it would
outlaw use of single quotes when it is supposed to be XML-compatible,
and XML explicitly allows either single or double quotes around attributes.
I checked a page or two at W3C and couldn't find an obvious way to
prove that you are wrong, but I think the onus is on you to prove
that you are right here.

XHTML 1.0 is XML, which allows both single quotes and double
quotes: http://www.w3.org/TR/REC-xml#NT-AttValue
HTML 4 is derived from SGML, which also supports both single
and double quotes, and also allows unquoted values, in some
cases: http://www.w3.org/TR/html4/intro/sgmltut.html#h-3.2.2

Peter Hansen enlightened us with: Are you certain about that? It seems very unlikely that it would outlaw use of single quotes when it is supposed to be XML-compatible, and XML explicitly allows either single or double quotes around attributes.
I can't find it right now, but I've had the same discussion with a few
collegues of mine, and according to W3C, both single and double quotes
are accepted for both HTML and XML, and thus XHTML too.

You're right--I was under the wrong impression about single & double quotes.
For some reason I recall reading somewhere (can't trust everything you read online)
that XML only allowed double quotes, and I never bothered to verify it.
Anyway, does that mean that the Qt parser has a bug?

If it wants to be HTML-compliant: yes.
If it wants to use HTML-like codes for markup: no
Al least, that's the way I see it. I dont't know Trolltech's
intentions. I'll check out the docs.

Jeremy Bowers enlightened us with: The confusion probably stems from the fact that as of the latest XHTML specification at the time I read it, every single example XHTML fragment used double quotes. At no point is it ever specified either way in the XHTML specification, except by reference to the XML specification.
Got a point there. I use single quotes all the time thouhg, in HTML generated
in PHP:
<?php
echo "<span class='$class'> $msg</span>"
?>
It's a lot better than something I otHften see in other people's code:
echo "<span class=\"$class\ ">$msg</span>"
Doing it the other way around doesn't work, since PHP doesn't do
variable substitution between single quotes.

which is the whole point, of course.
(we've been through this in the XML-RPC and RSS universes
lately; for some reason, some people have a really hard time
understanding that when you base a format on XML, you get
more than just tags in angle brackets ;-)

Jeremy Bowers enlightened us with: At no point is it ever specified either way in the XHTML specification, except by reference to the XML specification.
I'm sorry to tell you, but you're wrong in that. It is clearly stated in
the HTML 4.01 specification at http://www.w3.org/TR/html401/intro/sgmltut.html#h-3.2.2
I found that by going to the index, looking up the item "attibutes" and
then clicking the link at "quotation marks around value". Not that hard
to find.
The XML specification of attributes can be found at http://www.w3.org/TR/REC-xml#sec-common-syn and is a little harder to
find, but not impossible.
Since XHTML 1.0 is defined as "A Reformulation of HTML 4 in XML 1.0",
this should be enough to also allow single and double quoted attribute
values in XHTML.

Hello there,
Are there any out-of-the box handhelds that run Linux/Apache/MYSQL and
PHP? Does Redhat, Suse, or Gentoo support any handhelds?
I know the Zaurus comes close, but I've heard people have problems
running LAMP applications on it.
It would be cool to be able to run any LAMP application on sourceforge
on a handheld computer.
