XML til DTD igen
Hejsa.Jeg er igang med at oversætte et XML schema til DTD. Jeg har oprettet et spørgsmål før, men er stadigvæk noget i tvivl. Jeg har lagt helt schemaet ind, da der er en del elements der går igen, og det er der jeg kommet lidt i tvivl.
Her er schemaet:
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"xmlns:w="http://www.cs.au.dk/dWebTek/2011"targetNamespace="http://www.cs.au.dk/dWebTek/2011"elementFormDefault="qualified">

</schema>
Som det fremgår af det blå, er der flere steder, hvor fx Shopkey fremgår. Her kommer jeg så allerede i tvivl om den første ting. Skal Shopkey defineres to gange, dvs sellItems og adjustitemStock, eller skal den kun fremgå én gang?
jeg har skrevet dette her indtil videre, men er i tvivl om jeg overhovedet er på rette vej:
<!ELEMENT sellitems(shopKey,itemID,customerID,saleAmount)
<!ELEMENT ShopKey (#PCDATA)>
<!ELEMENT itemID (#PCDATA)>
<!ELEMENT customerID (#PCDATA)>
<!ELEMENT saleAmount (#PCDATA)>
<!ELEMENT adjustItemStock(#PCDATA)
<!ELEMENT itemName (#PCDATA)>
<!ELEMENT itenPrice(#PCDATA)>
<!ELEMENT itemDescription(#PCDATA)>
<!ELEMENT customerName(#PCDATA)>
<!ELEMENT customerPrice(#PCDATA)>
<!ELEMENT shopKey(#PCDATA)>
<!ELEMENT sale(#PCDATA)>
<!ELEMENT customer(#PCDATA)>
<!ELEMENT itemURL(#PCDATA)>
<!ELEMENT itemStock(#PCDATA)>
<!ELEMENT shopID(#PCDATA)>
<!ELEMENT shopName(#PCDATA)>
<!ELEMENT shopURL(#PCDATA)>
<!ELEMENT saleAmount()>
<!ELEMENT saleItemPrice()>
Håber i kan hjælpe mig på vej?
