6 XML::DOM::DocumentType - An XML document type (DTD) in XML::DOM
7
9 XML::DOM::DocumentType extends XML::DOM::Node.
10 Each Document has a doctype attribute whose value is either null or a
12 DocumentType object. The DocumentType interface in the DOM Level 1 Core
13 provides an interface to the list of entities that are defined for the
14 document, and little else because the effect of namespaces and the
15 various XML scheme efforts on DTD representation are not clearly
16 understood as of this writing. The DOM Level 1 doesn't support editing
17 DocumentType nodes.
18 Not In DOM Spec: This implementation has added a lot of extra
20 functionality to the DOM Level 1 interface. To allow editing of the
21 DocumentType nodes, see XML::DOM::ignoreReadOnly.
22 METHODS
24 getName
25 Returns the name of the DTD, i.e. the name immediately following
26 the DOCTYPE keyword.
27 getEntities
29 A NamedNodeMap containing the general entities, both external and
30 internal, declared in the DTD. Duplicates are discarded. For
31 example in:
32 <!DOCTYPE ex SYSTEM "ex.dtd" [
34 <!ENTITY foo "foo">
35 <!ENTITY bar "bar">
36 <!ENTITY % baz "baz">
37 ]>
38 <ex/>
39 the interface provides access to foo and bar but not baz. Every
41 node in this map also implements the Entity interface.
42 The DOM Level 1 does not support editing entities, therefore
44 entities cannot be altered in any way.
45 Not In DOM Spec: See XML::DOM::ignoreReadOnly to edit the
47 DocumentType etc.
48 getNotations
50 A NamedNodeMap containing the notations declared in the DTD.
51 Duplicates are discarded. Every node in this map also implements
52 the Notation interface.
53 The DOM Level 1 does not support editing notations, therefore
55 notations cannot be altered in any way.
56 Not In DOM Spec: See XML::DOM::ignoreReadOnly to edit the
58 DocumentType etc.
59 Additional methods not in the DOM Spec
61 Creating and setting the DocumentType
62 A new DocumentType can be created with:
63 $doctype = $doc->createDocumentType ($name, $sysId, $pubId, $internal);
65 To set (or replace) the DocumentType for a particular document,
67 use:
68 $doc->setDocType ($doctype);
70 getSysId and setSysId (sysId)
72 Returns or sets the system id.
73 getPubId and setPubId (pudId)
75 Returns or sets the public id.
76 setName (name)
78 Sets the name of the DTD, i.e. the name immediately following the
79 DOCTYPE keyword. Note that this should always be the same as the
80 element tag name of the root element.
81 getAttlistDecl (elemName)
83 Returns the AttlistDecl for the Element with the specified name, or
84 undef.
85 getElementDecl (elemName)
87 Returns the ElementDecl for the Element with the specified name, or
88 undef.
89 getEntity (entityName)
91 Returns the Entity with the specified name, or undef.
92 addAttlistDecl (elemName)
94 Adds a new AttDecl node with the specified elemName if one doesn't
95 exist yet. Returns the AttlistDecl (new or existing) node.
96 addElementDecl (elemName, model)
98 Adds a new ElementDecl node with the specified elemName and model
99 if one doesn't exist yet. Returns the AttlistDecl (new or
100 existing) node. The model is ignored if one already existed.
101 addEntity (notationName, value, sysId, pubId, ndata, parameter)
103 Adds a new Entity node. Don't use createEntity and appendChild,
104 because it should be added to the internal NamedNodeMap containing
105 the entities.
106 Parameters:
108 notationName the entity name.
109 value the entity value.
110 sysId the system id (if any.)
111 pubId the public id (if any.)
112 ndata the NDATA declaration (if any, for general unparsed
113 entities.)
114 parameter whether it is a parameter entity (%ent;) or not
115 (&ent;).
116 SysId, pubId and ndata may be undefined.
118 DOMExceptions:
120 • INVALID_CHARACTER_ERR
122 Raised if the notationName does not conform to the XML spec.
124 addNotation (name, base, sysId, pubId)
126 Adds a new Notation object.
127 Parameters:
129 name the notation name.
130 base the base to be used for resolving a relative URI.
131 sysId the system id.
132 pubId the public id.
133 Base, sysId, and pubId may all be undefined. (These parameters are
135 passed by the XML::Parser Notation handler.)
136 DOMExceptions:
138 • INVALID_CHARACTER_ERR
140 Raised if the notationName does not conform to the XML spec.
142 addAttDef (elemName, attrName, type, default, fixed)
144 Adds a new attribute definition. It will add the AttDef node to the
145 AttlistDecl if it exists. If an AttDef with the specified attrName
146 already exists for the given elemName, this function only generates
147 a warning.
148 See XML::DOM::AttDef::new for the other parameters.
150 getDefaultAttrValue (elem, attr)
152 Returns the default attribute value as a string or undef, if none
153 is available.
154 Parameters:
156 elem The element tagName.
157 attr The attribute name.
158 expandEntity (entity [, parameter])
160 Expands the specified entity or parameter entity (if parameter=1)
161 and returns its value as a string, or undef if the entity does not
162 exist. (The entity name should not contain the '%', '&' or ';'
163 delimiters.)
