# dtdNode(withXMLString:)

Returns a XMLDTDNode object representing the DTD declaration for an element, attribute, entity, or notation based on a given string.

## Declaration

```swift
class func dtdNode(withXMLString string: String) -> Any?
```

## Parameters

- `string`: A string that is a DTD declaration. The receiver parses this string to determine the kind of DTD node to create.

## Return Value

Return Value An NSXMLDTDNode object representing the DTD declaration or nil if the object couldn’t be created.

## Discussion

Discussion For example, if string is the following: <!ENTITY name (#PCDATA)> NSXMLNode is able to assign the created node object a kind of XMLNode.Kind.entityDeclaration by parsing “ENTITY”. Note that if an attribute-list declaration (<!ATTLIST...> )has multiple attributes NSXMLNode only creates an NSXMLDTDNode object for the last attribute in the declaration.
