RE: DTD question

Hubert:
I'm no XML expert but I believe the following statement goes against what a
DTD is supposed to do:

>but the order is not important...

A DTD's function is to make sure the XML conforms to the specified
structure.
I'm not certain if your use of the optional '?' operator is correct...

><!ELEMENT adresse ((vorname|nachname|othername),(telefon|fax|strasse|plz
			|stadt)?)>

...try this
<!ELEMENT adresse
((vorname|nachname|othername),telefon?,fax?,strasse?,plz?,stadt?)>

...there are tons of sites out there...here is a searchable list archive...

Subject:  DTD question


Hy,

I know that this is not a real XSL question, but it's connected with this
topic :-)

I have an element adress with several elements in it(prename, name, fax,
phone,street...)
and I want that these elements only may appear once, but the order is not
important, and that prename and name have to appear, the rest
don't have to but if they appear then just once of course.

How do I tell the dtd to do this?


I thought of something like this:

<!ELEMENT adresse ((vorname|nachname|othername),(telefon|fax|strasse|plz
			|stadt)?)>
	<!ELEMENT vorname (#PCDATA)>
	<!ELEMENT nachname (#PCDATA)>
	<!ELEMENT othername (#PCDATA)>
	<!ELEMENT telefon (#PCDATA)>
	<!ELEMENT fax (#PCDATA)>
	<!ELEMENT strasse (#PCDATA)>
	<!ELEMENT plz (#PCDATA)>
	<!ELEMENT stadt (#PCDATA)>


But this doesn't do what it is supposed to do and I know that this is not
working correctly because it's false for my needs, but i don't know how to
code it right.
Any suggestions or tutorial sites which are going a little bit deeper into
this topic than the zvon or equal stuff are welcome.

Thanks.
