Document DTD vol. 3

[Gianni Antini]

I don't understand why have add this line:

out.write("<!DOCTYPE document [\n");
:
:
out.write("]>\n");

in DTD generation. Now its again invalid.
There's a valid reason to do this?
The only reason that I can imaging is who you want to include your dtd definition inside XML document.

In my copy of your fantastic tool I have patched DTDGenerator with:

out.write("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n");

Hi Gianni,

your perfectly right, the DTD doesn't work that way. I've submitted several patches regarding that issue to CVS, please check them. One known open bug is regarding tags that may hold other tags or character data. Do you know how to declare stuff like that in DTDs?

Best regards,
Christian

Its very simple. You can use #PCDATA. Example:

<!ELEMENT paragraph (#PCDATA | B | I | U)*>
<!ATTLIST paragraph
    align (center | left | right | justify) #IMPLIED
    font CDATA #IMPLIED
    indentation CDATA #IMPLIED
    id CDATA #IMPLIED
>

PCDATA is what you want. There are other several improvement in your DTD. As example, if you want to use a default attribute:

<!ATTLIST paragraph
    align (center | left | right | justify) "left"
>

If you want to use ONLY letters, digits and point [ . ] , hyphen [ - ], underline [ _ ] and colon [ : ] you can use NMTOKEN instead CDATA:

<!ATTLIST paragraph
    font NMTOKEN #IMPLIED
        leftMargin NMTOKEN "10"
>

or NMTOKENS if you want use white space too. I hope this help you.
