NAME
    DOM-ecmascript - XML::Grove and ECMA Script Language Binding

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

    http://www.w3.org/TR/REC-DOM-Level-1/ ecma-script-language-binding.html
    <http://www.w3.org/TR/REC-DOM-Level-1/ecma-script-language-binding.html>

    The ECMA Script Language Binding presents DOM properties as ECMA Script object properties. The
    same is true for XML::Grove, XML::Grove presents DOM properties as Perl blessed hashes.

    The biggest difference between the ECMA Script Language Binding and XML::Grove is that
    XML::Grove uses a Perl hash for nodes, Perl arrays for NodeLists, Perl hashes for NamedNodeLists
    so those object classes don't exist in XML::Grove. Because those classes don't exist, you use
    ordinary Perl syntax for manipulating the DOM properties (lists and named node lists) instead of
    methods like `"nextSibling()"' or `"replaceChild()"'. Element attributes in XML::Grove are
    stored in Perl hashes; attribute types are available through the document object.

    Another difference is that XML::Grove attempts to marry the PerlSAX and DOM naming so that less
    (no?) name-changing occurs between using PerlSAX interfaces and filters and DOM modules. Where
    conflicts occur, the PerlSAX naming is used.

    XML::Grove uses a blessed hash for nodes, so the node type is available using Perl's `"ref()"'
    instead of using a `"nodeType()"' method and all class names are prefixed with `"XML::Grove::"'.

    The following object descriptions are the most basic and common provided by many PerlSAX
    parsers. PerlSAX parsers often provide additional properties or objects, refer to your PerlSAX
    parser documentation for details.

Document Object Model Level 1 Core
  Object XML::Grove::Document
    Contents    The children of this object. This property is an array.

    Entities    The entities declared in this document. This property is a hash of
                XML::Grove::Entity objects keyed by entity name.

    Notations   The notations declared in this document. This property is a hash of
                XML::Grove::Notation objects keyed by notation name.

  Object XML::Grove::Element
    Name        The tag type name for this element. This property is a string.

    Attributes  The attributes for this element. This property is a hash and it's hash values are
                strings (or arrays with some grove builders).

    Contents    The children of this object. This property is an array of XML::Grove objects.

  Object XML::Grove::Characters
    Data        The text of the character data. This property is a string.

  Object XML::Grove::Comment
    Data        The text of the character data. This property is a string.

  Object XML::Grove::CData
    The "CData" object is called a "CDATASection" in DOM.

    Data        The text of the character data. This property is a string.

  Object XML::Grove::Notation
    Name        The name of this notation. This property is a string.

    SystemId    The system identifier of this notation. This property is a string.

    PublicId    The public identifier of this notation. This property is a string.

  Object XML::Grove::Entity
    Name        The name of this entity. This property is a string.

    SystemId    The system identifier of this notation. This property is a string.

    PublicId    The public identifier of this notation. This property is a string.

    Notation    The notation declared for this entity. This property is either the name of the
                notation as a string or an "XML::Grove::Notation" object.

  Object XML::Grove::PI
    The "PI" object is called a "ProcessingInstruction" in DOM.

    Target      The target of the processing instruction. This property is a string.

    Data        The text of the processing instruction. This property is a string.
