[newbie] pb with entity

[Le TeXnicien de surface]

Hello

Here is my dtd
<?xml version="1.0" encoding="ISO-8859-15"?>
<!ENTITY APOS "’">
<!ELEMENT poeme (entete*, strophe+, final*) >
<!ELEMENT strophe (entete*, v+) >
<!ELEMENT v (#PCDATA) > <!-- un vers -->
<!ELEMENT entete (titre, avec_titre*) >
<!ELEMENT titre (#PCDATA) >
<!ELEMENT avec_titre ((dedicace | remarque | sous-titre)*) >

Here is a test file
<?xml version="1.0" encoding="ISO-8859-15" ?>
<!DOCTYPE yh_perso SYSTEM "./yh_perso.dtd">
<poeme>
<strophe>
<v>L&APOS;essai</v>
</strophe>
</poeme>

The problem is that Firefox yells about an undefined entity when
reading &APOS;

I've tried to find the solution with "xml in a nutshell" but I'm at
wit ends.
Any help appreciated. Thanks.

I've tried your file out, and find the same as you.

The Firefox XML parser appears to be totally broken as regards entity
declarations. At first I thought it was a problem that you have used
the upper-case version of a "built-in" entity (apos), but the same error
appears whatever the entity is called, and whether it is declared in the
external DTD or within the internal DTD subset in the document itself.
So I suggest you report this to Mozilla.

The same document (with the error noted above corrected) validates fine
with MSXML.

It's supposed to work if you make the entity decalaration in the local
subset. But mozilla family browsers such as firefox do not ever load
external dtd. Some "known" dtd are recognised and read from an internal
cache but the SYSTEM identifier is never used to fetch a dtd (for
performance and security reasons, they claim)

For some weird and stupid reason, Mozilla/Firefox will not download
external DTDs, so it will never see your declarations.

I have no idea why they did this, as it breaks the browser wrt XML.
Perhaps someone from the Moz community can answer.

The solution is to embed the declarations in the instance, eg:

<?xml version="1.0" encoding="ISO-8859-15" ?>
<!DOCTYPE yh_perso [
<!ENTITY APOS "’">
<!ELEMENT poeme (entete*, strophe+, final*) >
<!ELEMENT strophe (entete*, v+) >
<!ELEMENT v (#PCDATA) > <!-- un vers -->
<!ELEMENT entete (titre, avec_titre*) >
<!ELEMENT titre (#PCDATA) >
<!ELEMENT avec_titre ((dedicace | remarque | sous-titre)*) >
]>

Hmmm. Embedding it *used* to work. Maybe they've given up on XML
completely now. Maybe it's the signal for IE to make a comeback

I give up. I don't ever send XML to browsers anyway, only HTML.

Version number of your Firefox?

Works for me on Firefox 1.0.1, or more pedantically Mozilla/5.0 (X11;
U; Linux i686; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1

Also in Galeon 1.3.3, which shares Firefox's irritating
aversion to external entities of all sorts.

Odd, I have what appears to be the same version, but the internal subset
declaration of APOS works for me:

You're right; I'm wrong. With all the fiddling about between internal
and external DTD, and checking that the entity APOS wasn't getting mixed
up with the default entity apos, I ended declaring the entity as APOS1
and invoking it as APOS. So the slap on the wrist from Firefox was
entirely justified ...

This means that you _can_ still work around Firefox's failure to read an
external DTD by declaring entities in the internal DTD subset.

Apologies for any confusion or alarm,

But from the sound of it, entities only, not element or attribute
declarations?

Does anyone know why FF/Moz is so broken wrt XML? Are they antagonistic
to XML, or are they just dim? I find it hard to believe either.
