xml standard char set? (& minor zope thing ...)

Post #1 of 6 (4160 views)

Hi all,

I was wondering about python and the Unicode - ISO/IEC 10646 charset standard for XML. Legal characters are tab, carriage return, line feed, and the legal characters of Unicode and ISO/IEC 10646.

There's a problem when XML is manipulated via browser forms, like f.i. with XMLWidgets. Different browsers, even different OS versions of the same firm (i will use no names but ...) used in different countries (codepages) might well lead to difficulties.
I haven't read everything about it yet - and before i try to do that, is there anyone out there who has? And knows a solution for this?

By the way, just to be the naggin' horse i am, zope is inserting a nasty sub standard entity in my otherwise perfect html-4.01 template:

<base href=".. dot dot dot ..." />

The -->' /> '<-- part is not part of html. Shall i post a fix or will Zope 2.4.2 get rid of this ugly bird.

Greetings

The trailing slash is there is to make it compatible with XHTML. The lash
will be seen as an unknown attribute by non-XHTML browsers and ignored. See
the W3C XHTML recommendations.

Isn't the actual backwards compatibility that there's to be a space
between the / and the >? This ensures that it will be ignored. If
there's actually no space added by Zope I think we should make sure
it does.

Right; my understanding is that this is fairly common and supposed to work
with almost every browser, because it is treated as just another "unknown"
attribute, because the lexical rules for what constitutes an attribute in a
tag within most browser's parsers is farily forgiving to compensate for
mistakes.

The space is there. Note that Image objects generate an <img /> tag as well.

Formulator does too. I hope I do add the space there too. :)
