[−][src]Trait xml_dom::DocumentType
This corresponds to the DOM DocumentType
interface.
Specification
Each Document
has a doctype
attribute whose value is either null
or
a DocumentType
object. The DocumentType
interface in the DOM Core provides an interface
to the list of entities that are defined for the document, and little else because the effect
of namespaces and the various XML schema efforts on DTD representation are not clearly
understood as of this writing.
The DOM Level 2 doesn't support editing DocumentType
nodes.
Required methods
fn entities(&self) -> HashMap<Name, Self::NodeRef>
A NamedNodeMap
containing the general entities, both external and internal, declared in
the DTD. Parameter entities are not contained. Duplicates are discarded. For example in:
<!DOCTYPE ex SYSTEM "ex.dtd" [
<!ENTITY foo "foo">
<!ENTITY bar "bar">
<!ENTITY bar "bar2">
<!ENTITY % baz "baz">
]>
<ex/>
the interface provides access to foo
and the first declaration of bar
but not the
second declaration of bar
or baz
. Every node in this map also implements the Entity
interface.
The DOM Level 2 does not support editing entities, therefore entities
cannot be altered
in any way.
fn notations(&self) -> HashMap<Name, Self::NodeRef>
A NamedNodeMap
containing the notations declared in the DTD. Duplicates are discarded.
Every node in this map also implements the Notation
interface.
The DOM Level 2 does not support editing notations, therefore notations
cannot be altered
in any way.
fn public_id(&self) -> Option<String>
The public identifier of the external subset.
fn system_id(&self) -> Option<String>
The system identifier of the external subset.
fn internal_subset(&self) -> Option<String>
The internal subset as a string.
Note: The actual content returned depends on how much information is available to the implementation. This may vary depending on various parameters, including the XML processor used to build the document.
