Name
ElementDecl -- handler for element declarations in the DTD (V2.0)
Synopsis
ElementDecl(p, name$, type, quantifier, children)
Function
This function is called for element declarations in a DTD. The name of the element is passed in the name$ parameter. If type equals #XML_CTYPE_EMPTY or #XML_CTYPE_ANY, then quantifier will be #XML_CQUANT_NONE, and the children table will be Nil.

If type is #XML_CTYPE_MIXED, then quantifier will be #XML_CQUANT_NONE or #XML_CQUANT_REP and the children table will contain the elements that are allowed to be mixed in. All those children will have type #XML_CTYPE_NAME with no quantification then. Only the root node can be of type #XML_CTYPE_EMPTY, #XML_CTYPE_ANY, or #XML_CTYPE_MIXED.

For type #XML_CTYPE_NAME, the name$ parameter will contain the name and the children table will be Nil. The quantifier parameter will indicate any quantifiers placed on the name.

Types #XML_CTYPE_CHOICE and #XML_CTYPE_SEQ indicate a choice or sequence respectively. The children table then contains the nodes in the choice or sequence.

The children passed in the children table will have the fields name, type, quantifier, and children set. They correspond to the parameters of the same name passed to ElementDecl().

Possible values for the type parameter/field:

 
#XML_CTYPE_EMPTY
#XML_CTYPE_ANY
#XML_CTYPE_MIXED
#XML_CTYPE_NAME
#XML_CTYPE_CHOICE
#XML_CTYPE_SEQ

Possible values for the quantifier parameter/field:

 
#XML_CQUANT_NONE
#XML_CQUANT_OPT
#XML_CQUANT_REP
#XML_CQUANT_PLUS

Parameters
p

Example
Function p_ElementDecl(p, elname$, type, quant, children)
   DebugPrint(elname$, type, quant, children)
EndFunction

p = xml.CreateParser({ElementDecl = p_ElementDecl})
p:Parse([[
<!DOCTYPE student [
   <!ELEMENT student (id|surname)>
   <!ELEMENT id (#PCDATA)>
]>
<student>
   <id>9216735</id>
</student>
