New to XML, need some DTD help...

[twopecker]

I have the following file:

<?xml version="1.0" ?>
<!DOCTYPE League SYSTEM "DL.dtd">
<League LName="Eastern Developmental League">
<Team>
<Team_Name>Tigers</Team_Name>
<City>Toledo</City>
<Logo Source="Tigers"/>
<Players>
<Player Position="Centers" PPG="21.2" RPG="11.1">Lionel Diggs</Player>
<Player Position="Forward" PPG="18.9" RPG="8.4">Andrew Case</Player>
<Player Position="Forward" PPG="14.4" RPG="5.0">Casey Lewis</Player>
<Player Position="Guard" PPG="15.4" RPG="3.1" Assists="9.4">Andrew Case</Player>
<Player Position="Guard" PPG="7.2" RPG="2.5" Assists="3.9">Ray Kee</Player>
</Players>
</Team>
<Team>

And I am trying to make the following DTD file, but im not sure how to handle the "player" portion:

<!DOCTYPE League[

<!ELEMENT League (Team+)>
<!ELEMENT Team (#PCDATA)>

<!ELEMENT Team (Team_Name, City, Logo, Players+)>
<!ELEMENT Team_Name (#PCDATA)>
<!ELEMENT City (#PCDATA)>
<!ELEMENT Logo EMPTY>
<!ELEMENT Players (Player, Position, PPG, RPG)
<!ELEMENT Player>
<!ELEMENT Position ANY>
<!ELEMENT PPG ANY>
<!ELEMENT RPG ANY>


<!ATTLIST League Team CDATA #REQUIRED>
<!ATTLIST Team Logo CDATA #REQUIRED>
<!ATTLIST Player Position (Center|Forward|Guard)>


]>


Can anyone help a new guy out a bit? I've been going through all the tutorials I can find, but am sitll having problems.

Thanks!

Marcus,

I am no DTD expert, but here is what Stylus Studio generated.

<!ELEMENT League (Team)+>
<!ATTLIST League
  xmlns CDATA #FIXED ''
  LName CDATA #REQUIRED>

<!ELEMENT Team (Team_Name,City,Logo,Players)>
<!ATTLIST Team
  xmlns CDATA #FIXED ''>

<!ELEMENT Team_Name (#PCDATA)>
<!ATTLIST Team_Name
  xmlns CDATA #FIXED ''>

<!ELEMENT City (#PCDATA)>
<!ATTLIST City
  xmlns CDATA #FIXED ''>

<!ELEMENT Logo EMPTY>
<!ATTLIST Logo
  xmlns CDATA #FIXED ''
  Source  #REQUIRED>

<!ELEMENT Players (Player)+>
<!ATTLIST Players
  xmlns CDATA #FIXED ''>

<!ELEMENT Player (#PCDATA)>
<!ATTLIST Player
  xmlns CDATA #FIXED ''
  Assists  #IMPLIED
  PPG  #REQUIRED
  Position  #REQUIRED
  RPG  #REQUIRED>

Don't know if this is helpful or not.

Thanks for the reply...and im not sure if its helpful or not either. =)

I just bought a book to try to learn xml..sadly, i realized just a little ways in that it seems to be a text book with no answers! argh!

What do the entries for xmlns mean?

Centers"
PPG="21.2"
RPG="11.1"
Assists="9.4"
etc.

are not elements, they are just attributes of the Player element, hence they should be included just in the <!ATTLIST> declarations i guess.
I'd say it might look something like this:

<!ELEMENT players (player)>
<!ELEMENT Player (#PCDATA)>
<!ATTLIST Player Position (Center|Forward|Guard) #REQUIRED>

<!ATTLIST Player PPG CDATA #IMPLIED "21.2">
etc.
note: use #IMPLIED or #FIXED instead of #REQUIRED if needed

The same ought to go for the

<!ELEMENT Players (Player, Position, PPG, RPG)

"Position, PPG, RPG" are not elements, just attributes of the "Player" element hence cannot be stated as child elements of the "Players" element => Players(Position, PPG,RPG);

it is in deed only the "Player" that is the child element of the "Players" element, the others u had stated are just "Player"'s attributes.

And be careful about the tag ending signs.

<!ELEMENT Players (Player, Position, PPG, RPG)

I am just a rookie as well, so I could be wrong.
Cheers

How is it going, Marcus?

Actually, with what you provided, and then with venedos help, I was able to get it to work.

Quite the painful first experience though!

Thanks for your help.
