The ART element needs to be a child element of the ARTIST element which
needs to be a child of the CDLIST element.

Are you validating this against a schema? where is the schema?

Looking at your XML I suspect you need something to group together each
set of ARTIST, ART, ALBUM and SONGS elements. Maybe you have a missing
CD element that should act as a container within CDLIST?

The ART element needs to be a child element of the ARTIST element which
needs to be a child of the CDLIST element.
Click to expand...

hmm...isn't it a child with the

" 7 <!ELEMENT ARTIST (#PCDATA|ART)*> "

statement?

is this the wrong statement?

That is what your DTD defines and I tried to explain the DTD. But in
your XML later you have

<CDLIST>
20 <ARTIST Genre="Texas">Kevin Fowler</ARTIST>
21 <ART type="jpg" image="/images/KFowler.jpg" />

where ART is a child of CDLIST which is not what the DTD specifies.

This is *very* poor design. Mixed content is never appropriate in a
data-oriented document type. If this was supplied to you by your tutor,
complain. If you designed, it, you're excused at this stage :) It
should probably say:

<!ELEMENT CDLIST (ARTIST, ART*, ALBUM, SONGS, SITE)>
<!ELEMENT ARTIST (#PCDATA)>

You really, *really* don't want to be able to say

<ARTIST>John <ART type="jpg" image="foo"/> Doe <ART type="gif"
image="bar"/></ARTIST>

which is what the original allows. Tighten it up.

There are at least a dozen other remediable flaws in this design, but

This is invalid. The root element type must be CDINVENTORY like it says
in the Document Type Declaration. But the element type CDINVENTORY isn't
declared anywhere.

aha! thank you. that added some light to the subject. in short...for
each artist i will have to create a new instance of cdlist and i
needed that art element as a child of the artist. i misunderstood.

and no..the tutor didn't create this. i alone take full responsibility
for this debacle.

thanks for your assistance!

As you currently have it, yes. That may not be the optimal way to design
it, though. If you want it to be a list of albums, then maybe:

<cdlist>
<album>
<title>Wave on Wave</title>
<artist>Pat Green</artist>
<art type="jpg" image="/images/PGreen.jpg"/>
<songs>
<song type="ballad">Wave on Wave</song>
...more...
</songs>
<site>blah blah</site>
</album>
<album>
<title>etc</title>
...
</album>
and i
needed that art element as a child of the artist. i misunderstood.

There probably isn't any "right" solution. Just a lot of different ways
of expressing the same data.
and no..the tutor didn't create this. i alone take full responsibility
for this debacle.

NP. We all had to start somewhere.
