-#
-# To do:
-#
-# * optimize Attr if it only contains 1 Text node to hold the value
-# * fix setDocType!
-#
-# * BUG: setOwnerDocument - does not process default attr values correctly,
-# they still point to the old doc.
-# * change Exception mechanism
-# * maybe: more checking of sysId etc.
-# * NoExpand mode (don't know what else is useful)
-# * various odds and ends: see comments starting with "??"
-# * normalize(1) could also expand CDataSections and EntityReferences
-# * parse a DocumentFragment?
-# * encoding support
-#

-
-XML::DOM - A perl module for building DOM Level 1 compliant document structures
-
-=head1 SYNOPSIS
-
- use XML::DOM;
-
- my $parser = new XML::DOM::Parser;
- my $doc = $parser->parsefile ("file.xml");
-
- # print all HREF attributes of all CODEBASE elements
- my $nodes = $doc->getElementsByTagName ("CODEBASE");
- my $n = $nodes->getLength;
-
- for (my $i = 0; $i < $n; $i++)
- {
- my $node = $nodes->item ($i);
- my $href = $node->getAttributeNode ("HREF");
- print $href->getValue . "\n";
- }
-
- # Print doc file
- $doc->printToFile ("out.xml");
-
- # Print to string
- print $doc->toString;
-
- # Avoid memory leaks - cleanup circular references for garbage collection
- $doc->dispose;
-
-=head1 DESCRIPTION
-
-This module extends the XML::Parser module by Clark Cooper.
-The XML::Parser module is built on top of XML::Parser::Expat,
-which is a lower level interface to James Clark's expat library.
-
-XML::DOM::Parser is derived from XML::Parser. It parses XML strings or files
-and builds a data structure that conforms to the API of the Document Object
-Model as described at http://www.w3.org/TR/REC-DOM-Level-1.
-See the XML::Parser manpage for other available features of the
-XML::DOM::Parser class.
-Note that the 'Style' property should not be used (it is set internally.)
-
-The XML::Parser I<NoExpand> option is more or less supported, in that it will
-generate EntityReference objects whenever an entity reference is encountered
-in character data. I'm not sure how useful this is. Any comments are welcome.
-
-As described in the synopsis, when you create an XML::DOM::Parser object,
-the parse and parsefile methods create an I<XML::DOM::Document> object
-from the specified input. This Document object can then be examined, modified and
-written back out to a file or converted to a string.
-
-When using XML::DOM with XML::Parser version 2.19 and up, setting the
-XML::DOM::Parser option I<KeepCDATA> to 1 will store CDATASections in
-CDATASection nodes, instead of converting them to Text nodes.
-Subsequent CDATASection nodes will be merged into one. Let me know if this
-is a problem.
-
-When using XML::Parser 2.27 and above, you can suppress expansion of
-parameter entity references (e.g. %pent;) in the DTD, by setting I<ParseParamEnt>
-to 1 and I<ExpandParamEnt> to 0. See L<Hidden Nodes|/_Hidden_Nodes_> for details.
-
-A Document has a tree structure consisting of I<Node> objects. A Node may contain
-other nodes, depending on its type.
-A Document may have Element, Text, Comment, and CDATASection nodes.
-Element nodes may have Attr, Element, Text, Comment, and CDATASection nodes.
-The other nodes may not have any child nodes.
-
-This module adds several node types that are not part of the DOM spec (yet.)
-These are: ElementDecl (for <!ELEMENT ...> declarations), AttlistDecl (for
-<!ATTLIST ...> declarations), XMLDecl (for <?xml ...?> declarations) and AttDef
-(for attribute definitions in an AttlistDecl.)
-
-=head1 XML::DOM Classes
-
-The XML::DOM module stores XML documents in a tree structure with a root node
-of type XML::DOM::Document. Different nodes in tree represent different
-parts of the XML file. The DOM Level 1 Specification defines the following
-node types:
-
-=over 4
-
-=item * L<XML::DOM::Node> - Super class of all node types
-
-=item * L<XML::DOM::Document> - The root of the XML document
-
-=item * L<XML::DOM::DocumentType> - Describes the document structure: <!DOCTYPE root [ ... ]>
-
-=item * L<XML::DOM::Element> - An XML element: <elem attr="val"> ... </elem>
-
-=item * L<XML::DOM::Attr> - An XML element attribute: name="value"
-
-=item * L<XML::DOM::CharacterData> - Super class of Text, Comment and CDATASection
-
-=item * L<XML::DOM::Text> - Text in an XML element
-
-=item * L<XML::DOM::CDATASection> - Escaped block of text: <![CDATA[ text ]]>
-
-=item * L<XML::DOM::Comment> - An XML comment: <!-- comment -->
-
-=item * L<XML::DOM::EntityReference> - Refers to an ENTITY: &ent; or %ent;
-
-=item * L<XML::DOM::Entity> - An ENTITY definition: <!ENTITY ...>
-
-=item * L<XML::DOM::ProcessingInstruction> - <?PI target>
-
-=item * L<XML::DOM::DocumentFragment> - Lightweight node for cut & paste
-
-=item * L<XML::DOM::Notation> - An NOTATION definition: <!NOTATION ...>
-
-=back
-
-In addition, the XML::DOM module contains the following nodes that are not part
-of the DOM Level 1 Specification:
-
-=over 4
-
-=item * L<XML::DOM::ElementDecl> - Defines an element: <!ELEMENT ...>
-
-=item * L<XML::DOM::AttlistDecl> - Defines one or more attributes in an <!ATTLIST ...>
-
-=item * L<XML::DOM::AttDef> - Defines one attribute in an <!ATTLIST ...>
-
-=item * L<XML::DOM::XMLDecl> - An XML declaration: <?xml version="1.0" ...>
-
-=back
-
-Other classes that are part of the DOM Level 1 Spec:
-
-=over 4
-
-=item * L<XML::DOM::Implementation> - Provides information about this implementation. Currently it doesn't do much.
-
-=item * L<XML::DOM::NodeList> - Used internally to store a node's child nodes. Also returned by getElementsByTagName.
-
-=item * L<XML::DOM::NamedNodeMap> - Used internally to store an element's attributes.
-
-=back
-
-Other classes that are not part of the DOM Level 1 Spec:
-
-=over 4
-
-=item * L<XML::DOM::Parser> - An non-validating XML parser that creates XML::DOM::Documents
-
-=item * L<XML::DOM::ValParser> - A validating XML parser that creates XML::DOM::Documents. It uses L<XML::Checker> to check against the DocumentType (DTD)
-
-=item * L<XML::Handler::BuildDOM> - A PerlSAX handler that creates XML::DOM::Documents.
-
-=back
-
-=head1 XML::DOM package
-
-=over 4
-
-=item Constant definitions
-
-The following predefined constants indicate which type of node it is.
-
-=back
-
- UNKNOWN_NODE (0) The node type is unknown (not part of DOM)
-
- ELEMENT_NODE (1) The node is an Element.
- ATTRIBUTE_NODE (2) The node is an Attr.
- TEXT_NODE (3) The node is a Text node.
- CDATA_SECTION_NODE (4) The node is a CDATASection.
- ENTITY_REFERENCE_NODE (5) The node is an EntityReference.
- ENTITY_NODE (6) The node is an Entity.
- PROCESSING_INSTRUCTION_NODE (7) The node is a ProcessingInstruction.
- COMMENT_NODE (8) The node is a Comment.
- DOCUMENT_NODE (9) The node is a Document.
- DOCUMENT_TYPE_NODE (10) The node is a DocumentType.
- DOCUMENT_FRAGMENT_NODE (11) The node is a DocumentFragment.
- NOTATION_NODE (12) The node is a Notation.
-
- ELEMENT_DECL_NODE (13) The node is an ElementDecl (not part of DOM)
- ATT_DEF_NODE (14) The node is an AttDef (not part of DOM)
- XML_DECL_NODE (15) The node is an XMLDecl (not part of DOM)
- ATTLIST_DECL_NODE (16) The node is an AttlistDecl (not part of DOM)
-
- Usage:
-
- if ($node->getNodeType == ELEMENT_NODE)
- {
- print "It's an Element";
- }
-
-B<Not In DOM Spec>: The DOM Spec does not mention UNKNOWN_NODE and,
-quite frankly, you should never encounter it. The last 4 node types were added
-to support the 4 added node classes.
-
-=head2 Global Variables
-
-=over 4
-
-=item $VERSION
-
-The variable $XML::DOM::VERSION contains the version number of this
-implementation, e.g. "1.42".
-
-=back
-
-=head2 METHODS
-
-These methods are not part of the DOM Level 1 Specification.
-
-=over 4
-
-=item getIgnoreReadOnly and ignoreReadOnly (readOnly)
-
-The DOM Level 1 Spec does not allow you to edit certain sections of the document,
-e.g. the DocumentType, so by default this implementation throws DOMExceptions
-(i.e. NO_MODIFICATION_ALLOWED_ERR) when you try to edit a readonly node.
-These readonly checks can be disabled by (temporarily) setting the global
-IgnoreReadOnly flag.
-
-The ignoreReadOnly method sets the global IgnoreReadOnly flag and returns its
-previous value. The getIgnoreReadOnly method simply returns its current value.
-
- my $oldIgnore = XML::DOM::ignoreReadOnly (1);
- eval {
- ... do whatever you want, catching any other exceptions ...
- };
- XML::DOM::ignoreReadOnly ($oldIgnore); # restore previous value
-
-Another way to do it, using a local variable:
-
- { # start new scope
- local $XML::DOM::IgnoreReadOnly = 1;
- ... do whatever you want, don't worry about exceptions ...
- } # end of scope ($IgnoreReadOnly is set back to its previous value)
-
-
-=item isValidName (name)
-
-Whether the specified name is a valid "Name" as specified in the XML spec.
-Characters with Unicode values > 127 are now also supported.
-
-=item getAllowReservedNames and allowReservedNames (boolean)
-
-The first method returns whether reserved names are allowed.
-The second takes a boolean argument and sets whether reserved names are allowed.
-The initial value is 1 (i.e. allow reserved names.)
-
-The XML spec states that "Names" starting with (X|x)(M|m)(L|l)
-are reserved for future use. (Amusingly enough, the XML version of the XML spec
-(REC-xml-19980210.xml) breaks that very rule by defining an ENTITY with the name
-'xmlpio'.)
-A "Name" in this context means the Name token as found in the BNF rules in the
-XML spec.
-
-XML::DOM only checks for errors when you modify the DOM tree, not when the
-DOM tree is built by the XML::DOM::Parser.
-
-=item setTagCompression (funcref)
-
-There are 3 possible styles for printing empty Element tags:
-
-=over 4
-
-=item Style 0
-
- <empty/> or <empty attr="val"/>
-
-XML::DOM uses this style by default for all Elements.
-
-=item Style 1
-
- <empty></empty> or <empty attr="val"></empty>
-
-=item Style 2
-
- <empty /> or <empty attr="val" />
-
-This style is sometimes desired when using XHTML.
-(Note the extra space before the slash "/")
-See L<http://www.w3.org/TR/xhtml1> Appendix C for more details.
-
-=back
-
-By default XML::DOM compresses all empty Element tags (style 0.)
-You can control which style is used for a particular Element by calling
-XML::DOM::setTagCompression with a reference to a function that takes
-2 arguments. The first is the tag name of the Element, the second is the
-XML::DOM::Element that is being printed.
-The function should return 0, 1 or 2 to indicate which style should be used to
-print the empty tag. E.g.
-
- XML::DOM::setTagCompression (\&my_tag_compression);
-
- sub my_tag_compression
- {
- my ($tag, $elem) = @_;
-
- # Print empty br, hr and img tags like this: <br />
- return 2 if $tag =~ /^(br|hr|img)$/;
-
- # Print other empty tags like this: <empty></empty>
- return 1;
- }
-
-=back
-
-=head1 IMPLEMENTATION DETAILS
-
-=over 4
-
-=item * Perl Mappings
-
-The value undef was used when the DOM Spec said null.
-
-The DOM Spec says: Applications must encode DOMString using UTF-16 (defined in
-Appendix C.3 of [UNICODE] and Amendment 1 of [ISO-10646]).
-In this implementation we use plain old Perl strings encoded in UTF-8 instead of
-UTF-16.
-
-=item * Text and CDATASection nodes
-
-The Expat parser expands EntityReferences and CDataSection sections to
-raw strings and does not indicate where it was found.
-This implementation does therefore convert both to Text nodes at parse time.
-CDATASection and EntityReference nodes that are added to an existing Document
-(by the user) will be preserved.
-
-Also, subsequent Text nodes are always merged at parse time. Text nodes that are
-added later can be merged with the normalize method. Consider using the addText
-method when adding Text nodes.
-
-=item * Printing and toString
-
-When printing (and converting an XML Document to a string) the strings have to
-encoded differently depending on where they occur. E.g. in a CDATASection all
-substrings are allowed except for "]]>". In regular text, certain characters are
-not allowed, e.g. ">" has to be converted to "&gt;".
-These routines should be verified by someone who knows the details.
-
-=item * Quotes
-
-Certain sections in XML are quoted, like attribute values in an Element.
-XML::Parser strips these quotes and the print methods in this implementation
-always uses double quotes, so when parsing and printing a document, single quotes
-may be converted to double quotes. The default value of an attribute definition
-(AttDef) in an AttlistDecl, however, will maintain its quotes.
-
-=item * AttlistDecl
-
-Attribute declarations for a certain Element are always merged into a single
-AttlistDecl object.
-
-=item * Comments
-
-Comments in the DOCTYPE section are not kept in the right place. They will become
-child nodes of the Document.
-
-=item * Hidden Nodes
-
-Previous versions of XML::DOM would expand parameter entity references
-(like B<%pent;>), so when printing the DTD, it would print the contents
-of the external entity, instead of the parameter entity reference.
-With this release (1.27), you can prevent this by setting the XML::DOM::Parser
-options ParseParamEnt => 1 and ExpandParamEnt => 0.
-
-When it is parsing the contents of the external entities, it *DOES* still add
-the nodes to the DocumentType, but it marks these nodes by setting
-the 'Hidden' property. In addition, it adds an EntityReference node to the
-DocumentType node.
-
-When printing the DocumentType node (or when using to_expat() or to_sax()),
-the 'Hidden' nodes are suppressed, so you will see the parameter entity
-reference instead of the contents of the external entities. See test case
-t/dom_extent.t for an example.
-
-The reason for adding the 'Hidden' nodes to the DocumentType node, is that
-the nodes may contain <!ENTITY> definitions that are referenced further
-in the document. (Simply not adding the nodes to the DocumentType could
-cause such entity references to be expanded incorrectly.)
-
-Note that you need XML::Parser 2.27 or higher for this to work correctly.

-
-The DOM Level 1 specification at L<http://www.w3.org/TR/REC-DOM-Level-1>

-
-The L<XML::Parser> and L<XML::Parser::Expat> manual pages.
-
-L<XML::LibXML> also provides a DOM Parser, and is significantly faster
-than XML::DOM, and is under active development. It requires that you
-download the Gnome libxml library.
-
-L<XML::GDOME> will provide the DOM Level 2 Core API, and should be
-as fast as XML::LibXML, but more robust, since it uses the memory
-management functions of libgdome. For more details see
-L<http://tjmather.com/xml-gdome/>
-
-=head1 CAVEATS
-
-The method getElementsByTagName() does not return a "live" NodeList.
-Whether this is an actual caveat is debatable, but a few people on the
-www-dom mailing list seemed to think so. I haven't decided yet. It's a pain
-to implement, it slows things down and the benefits seem marginal.
-Let me know what you think.

- See L<XML::DOM::BuildDOM>
-
-=head1 DESCRIPTION
-
-XML::DOM::PerlSAX was renamed to L<XML::Handler::BuildDOM> to comply
-with naming conventions for PerlSAX filters/handlers.
-
-For backward compatibility, this package will remain in existence
-(it simply includes XML::Handler::BuildDOM), but it will print a warning when
-running with I<'perl -w'>.

-=head1 NAME
-
-XML::Handler::BuildDOM - PerlSAX handler that creates XML::DOM document structures
-
-=head1 SYNOPSIS
-
- use XML::Handler::BuildDOM;
- use XML::Parser::PerlSAX;
-
- my $handler = new XML::Handler::BuildDOM (KeepCDATA => 1);
- my $parser = new XML::Parser::PerlSAX (Handler => $handler);
-
- my $doc = $parser->parsefile ("file.xml");
-
-=head1 DESCRIPTION
-
-XML::Handler::BuildDOM creates L<XML::DOM> document structures
-(i.e. L<XML::DOM::Document>) from PerlSAX events.
-
-This class used to be called L<XML::PerlSAX::DOM> prior to libxml-enno 1.0.1.
-
-=head2 CONSTRUCTOR OPTIONS
-
-The XML::Handler::BuildDOM constructor supports the following options:
-
-=over 4
-
-=item * KeepCDATA => 1
-
-If set to 0 (default), CDATASections will be converted to regular text.
-
-=item * Document => $doc
-
-If undefined, start_document will extract it from Element or DocType (if set),
-otherwise it will create a new XML::DOM::Document.
-
-=item * Element => $elem
-
-If undefined, it is set to Document. This will be the insertion point (or parent)
-for the nodes defined by the following callbacks.
-
-=item * DocType => $doctype
-
-If undefined, start_document will extract it from Document (if possible).
-Otherwise it adds a new XML::DOM::DocumentType to the Document.
