6 XML::Grove is similar in concept to the ECMA Script Language Binding to
7 DOM Level 1 Core (Appendix E of the DOM Recommendation).

10
11 The ECMA Script Language Binding presents DOM properties as ECMA Script
12 object properties. The same is true for XML::Grove, XML::Grove
13 presents DOM properties as Perl blessed hashes.
14
15 The biggest difference between the ECMA Script Language Binding and
16 XML::Grove is that XML::Grove uses a Perl hash for nodes, Perl arrays
17 for NodeLists, Perl hashes for NamedNodeLists so those object classes
18 don't exist in XML::Grove. Because those classes don't exist, you use
19 ordinary Perl syntax for manipulating the DOM properties (lists and
20 named node lists) instead of methods like `"nextSibling()"' or
21 `"replaceChild()"'. Element attributes in XML::Grove are stored in
22 Perl hashes; attribute types are available through the document object.
23
24 Another difference is that XML::Grove attempts to marry the PerlSAX and
25 DOM naming so that less (no?) name-changing occurs between using
26 PerlSAX interfaces and filters and DOM modules. Where conflicts occur,
27 the PerlSAX naming is used.
28
29 XML::Grove uses a blessed hash for nodes, so the node type is available
30 using Perl's `"ref()"' instead of using a `"nodeType()"' method and all
31 class names are prefixed with `"XML::Grove::"'.
32
33 The following object descriptions are the most basic and common
34 provided by many PerlSAX parsers. PerlSAX parsers often provide
35 additional properties or objects, refer to your PerlSAX parser
36 documentation for details.
37
39 Object XML::Grove::Document
40 Contents The children of this object. This property is an array.
41
42 Entities The entities declared in this document. This property is a
43 hash of XML::Grove::Entity objects keyed by entity name.
44
45 Notations The notations declared in this document. This property is
46 a hash of XML::Grove::Notation objects keyed by notation
47 name.
48
49 Object XML::Grove::Element
50 Name The tag type name for this element. This property is a
51 string.
52
53 Attributes The attributes for this element. This property is a hash
54 and it's hash values are strings (or arrays with some grove
55 builders).
56
57 Contents The children of this object. This property is an array of
58 XML::Grove objects.
59
60 Object XML::Grove::Characters
61 Data The text of the character data. This property is a string.
62
63 Object XML::Grove::Comment
64 Data The text of the character data. This property is a string.
65
66 Object XML::Grove::CData
67 The "CData" object is called a "CDATASection" in DOM.
68
69 Data The text of the character data. This property is a string.
70
71 Object XML::Grove::Notation
72 Name The name of this notation. This property is a string.
73
74 SystemId The system identifier of this notation. This property is a
75 string.
76
77 PublicId The public identifier of this notation. This property is a
78 string.
79
80 Object XML::Grove::Entity
81 Name The name of this entity. This property is a string.
82
83 SystemId The system identifier of this notation. This property is a
84 string.
85
86 PublicId The public identifier of this notation. This property is a
87 string.
88
89 Notation The notation declared for this entity. This property is
90 either the name of the notation as a string or an
91 "XML::Grove::Notation" object.
92
93 Object XML::Grove::PI
94 The "PI" object is called a "ProcessingInstruction" in DOM.
95
96 Target The target of the processing instruction. This property is
97 a string.
98
99 Data The text of the processing instruction. This property is a
100 string.
