So I was designing an XML file based on a certain DTD. The logic is thus:
Category >> Books(can have many entries) >>Author[required], Price[required], Description, Image)
Here is the DTD generated:
Quote: <!ELEMENT CATAGORY (PRODUCT+)>
<!ELEMENT PRODUCT
(NAME,PRICE,DESCRIPTION*,PICTURE*)>
<!ATTLIST PRODUCT
NAME CDATA #REQUIRED
PRICE CDATA #REQUIRED
DESCRIPTION CDATA #IMPLIED
PICTURE CDATA #IMPLIED
CATEGORY (BOOKS|GADGETS|OTHERS) "BOOKS"
AUTHOR CDATA #REQUIRED
ISBN CDATA #IMPLIED
INVENTORY (InStock|Backordered|Discontinued) "InStock">
However, I am unable to write a valid XML. I wrote thus:
Quote:<CATAGORY> <PRODUCT NAME="XML BOOK" AUTHOR="XML GENIUS" CATEGORY="BOOKS" DESCRIPTION="BRILLIANT XML BOOK." INVENTORY="InStock" ISBN="653725327" PRICE="36.99" PICTURE=""/> <PRODUCT NAME="XML MASTERS" AUTHOR="XML TEACHER" CATEGORY="BOOKS" DESCRIPTION="" INVENTORY="InStock" ISBN="" PICTURE="" PRICE="23.99"/> </CATAGORY>
I get the following error from XML SPY. Any help is appreciated.
Quote: Content model of element <PRODUCT> requires further child elements. Error location: CATAGORY / PRODUCT Details VC: Element Valid (2): Content model of element <PRODUCT> requires further child elements.
P.S. I am absolutely new to XML and DTDs so my apologies.

with the xml file open, select Generate DTD/Schema in the DTD/Schema menu. This will generate the appropriate dtd or xsd from your xml file.
