This produces the same error message when using nsgmls.exe nsgmls -s -m d:\\sp\\catalog d:\\sp\\html.dec addr3-2.htm addr3-2.htm:6:19:E: end tag for `ADDRESS' omitted, but its declaration does not permit this addr3-2.htm:6:7: start tag was here addr3-2.htm:6:33:E: end tag for element `ADDRESS' which is not open However as mentioned in the post this won't produce an error. \ \ \ \Test\
The problem as I see it today is (I don't understand SGML stuff yet) 1. Since the HTML 3.0 DTD fragment has mixed content [2] the newline character won't be ignored and 2. The parser gets stuck on the %text; path of the model group ((%text;)* | P*) and can't get to the P element. I _believe_ that the parser needs an \ to get out of the %text; path. This is why I replaced the HTML 3.0 DTD content model with the HTML2.0 content model for ADDRESS. \ Simple? Well it works :). ---- Note 2: There is either Data or Element Content. "If data can be entered into within in the element it is said to have mixed content. The significance of the distinction is that, within element content, separator characters suchs as spaces, record starts, record ends and Tabs are ignored" " [P270 of Bryan's book -- It costs $32.50] : YAUOMC : Yet Another Use Of Mixed Content: See section 7.6 of the ISO standard starting on page 319 of "The SGML Handbook" [1] for the authoritative explanation of mixed content. Or if you are like me and not very SGML and Parser literate read pages 269-271 of this great book. Bryan, Martin. SGML; An Author's Guide to the Standard Generalized Markup Language. Addison-Wesley Publishers, Ltd., 1988. ISBN 0-201-17535-5. QA76.73.S44B79 1988. It should be in many good bookstores. I find that this book uses language to explain what is really going on in this SGML stuff. For example Martin Bryan discusses "Tag Recognition" before he talks about mixed content. He takes a few paragraphs to explain what the parser is doing--other SGML books didn't do that. I like this book. Oh, if you go to a bookstore to look at SGML books, read pages 312-5 of Travis, Brian E. & Waldt, Dale C. The SGML Implementation Guide: A Blueprint for SGML Migration. Springer-Verlag, 1995. ISBN 3-540-57730-0 QA76.76.H94T73 1995. --- Note 1: Goldfarb, Charles F. The SGML Handbook. Oxford: Clarendon Press, 1990. ISBN 0-19-853737-9. Z286.E43G64 1990. I hope this is helpful and I hope someone will PLEASE correct anything I've written here.
