I have an example of DTD script here, and I was wondering if they are valid, are there any online validator for DTD?
<!ELEMENT A (B* |C+,D)>
<ATTLIST A
AA CDATA #REQUIRED
AB CDATA #REQUIRED
AC(0|1|2) #REQUIRED
>
<!ELEMENT B EMPTY>
<!ATTLIST C(B)>
And Another Question. in the line
!ELEMENT B EMPTY>
<!ATTLIST C(B)>
What does that actually mean? can any one provide example?
And this A (B* |C+,D)
Try this XML DTD validator (dead link removed).
