Revision history for HTML::DOM

0.010   23 December, 2007
        New features:
        • HTML::DOM::Node’s trigger_event method now returns nothing.
          (It used to return the return value of the  default  event
          handler.)  As  a  side  effect,  this  fixes  a  few  bugs.
        • The classes for HTML tables and frames have been added.
        • HTML::DOM::Element now has a content_offset method.
        • HTML::DOM::Element::Form now has its reset method.
        • The DOM Level-2 core interfaces are now supported.
        • I’ve started work on CSS features. So far, elements have a
         ‘style’ method.
        • You can now access forms by using an HTML::DOM object as
          a hash ref.
        • A checkbox’s click method now toggles the checkbox’s state.
        Fixed bugs:
        • HTML::DOM::Element::Form’s submit method now
          returns nothing.
        • HTML::DOM::Element::Select’s blur and focus methods now
          return nothing.
        • HTML::DOM::Element::Button’s type method now works.
        • HTML::DOM::Element::Label’s htmlFor method now works.
        • Heading elements (h1..h6) are now blessed into the
          HTML::DOM::Element::Heading class,  so  the  align
          method works.
        • HTML::DOM::Element::Object’s useMap method now works.
        • HTML::DOM::Element::Applet’s codeBase method now works.
        • tbody elements are now inserted into the tree if a <tr>
          occurs directly within a <table>.
        • HTML::DOM::Interface now includes  HTML::DOM::TreeBuilder,
          which is used for the document’s <html> element while the
          HTML code is being parsed.
        • The as_text and as_HTML methods now work on the document’s
          <html> element during parsing.
        • The <html> element’s ‘version’ method now works dur-
          ing parsing.
        • getElementById and getElementsByTagName now stringify the
          name or ID  (in order to make  HTML::Element’s  look_down
          method happy).  These both used to return false negatives
          when passed objects with string overloading.
        • HTML::DOM::Element’s normalize method (which has been moved
          to HTML::DOM::Node) now actually does something.
        • HTML::DOM::Node’s cloneNode method used not  to  erase  the
          clone’s parentNode attribute unless the  cloning  was  deep.
          Nor did it erase the list of child nodes in a shallow clone,
          so those nodes would have multiple parents.
        • cloneNode now works with HTML elements (the attributes are
          now cloned).
        • HTML::DOM::CharacterData’s deleteData16  method  now  works
          properly, instead of getting offsets wrong and then convert-
          ing all the text into UTF-16.
        • HTML::DOM::Collection’s namedItem method used to return
          undef for form, img and map elements.
        • HTML::DOM::Collection::Elements’s namedItem method used to
          die if there were multiple form fields with the same  name.

        Changes/new features:
        *  You can do something with errors produced by event handlers
           by passing a coderef to the new event_handler method.  That
           coderef will be called for each error. (Before, such errors
           were ignored.)
        *  HTML::DOM::Interface has been modified, such that
          'Document' is no longer a separate interface--since there is
           no corresponding HTML::DOM module--,  but all  its  members
           are  now under HTMLDocument,  which inherits directly  from
           Node. Likewise, 'Element' has been merged into HTMLElement.
        *  HTML::DOM::Element::Select now has 'add' and
          'remove' methods.
        * 'Select' elements can now be used as array refs, so you can
           write $select->[0] instead of $select->options->[0].
        *  You can now assign undef to such an array element to delete
           it,  so  '$select->[0] = undef'  does  the  same  thing  as
          'shift @$select'. 'delete $select->[0]' also works.
        Bug fixes:
        * $form->action now works when the document has no base url
          (used to die)
        * HTML::DOM::Element::Select's type method now works.
        * HTML::DOM::Element::Select's  selectedIndex  method  and
          HTML::DOM::Element::Option's selected method should work
          reliably now.
        * HTML::DOM::Collection::Options is now listed by
          HTML::DOM::Interface.
        * HTML::DOM::Element::Input's click method now returns an
          empty list.
        * HTML::DOM's event_attr_handler is now actually useful. (It
          used to be ignored most of the time.)

0.008   5 October, 2007
        * New HTML::DOM::Interface module
        * Added type and value methods to HTML::DOM::Element::Button
        * Added the charset, coords and tabIndex methods to 
          HTML::DOM::Element::A.
        * HTML::DOM's createElement method now throws an 
          HTML::DOM::Exception.

0.007   29 September, 2007
        Two bug fixes:
        * The URL method no longer warns if there is no URL.
        * The previous release broke parsing of forms. (The rest of
          the document would be within the form element.) Now it
          should work.

0.006   27 September, 2007
      - The following interfaces have been implemented:
            HTMLFormElement
            HTMLSelectElement
            HTMLOptGroupElement
            HTMLOptionElement
            HTMLInputElement
            HTMLTextAreaElement
            HTMLButtonElement
            HTMLLabelElement
            HTMLFieldSetElement
            HTMLLegendElement
            HTMLUListElement
            HTMLOListElement
            HTMLDListElement
            HTMLDirectoryElement
            HTMLMenuElement
            HTMLLIElement
            HTMLDivElement
            HTMLParagraphElement
            HTMLHeadingElement
            HTMLQuoteElement
            HTMLPreElement
            HTMLBRElement
            HTMLBaseFontElement
            HTMLFontElement
            HTMLHRElement
            HTMLModElement
            HTMLAnchorElement
            HTMLImageElement
            HTMLObjectElement
            HTMLParamElement
            HTMLAppletElement
            HTMLMapElement
            HTMLAreaElement
            HTMLScriptElement
      - Some methods have also been added for compatibility with 
        WWW::Mechanize.
      - The 'open' method no longer stops the ownerDocument method
        from working properly.
      - Furthermore,  'open' is no longer anywhere near as powerful as
        it was; it used to obliterate the coderefs that were passed to
        event_attr_handler and default_event_handler.
      - &HTML::DOM::base has been added.
      - The parse and eof methods have been deleted, since write and
        close do the same thing.

0.005   26 August, 2007
        The HTMLCollection interface has now been implemented, and so
        have the attribute  methods  of  the  HTMLDocument  interface
        (Level 1). The HTMLHtmlElement, HTMLHeadElement,
        HTMLLinkElement, HTMLTitleElement, HTMLMetaElement,
        HTMLBaseElement, HTMLIsIndexElement, HTMLStyleElement and
        HTMLBodyElement interfaces (again, Level 1) have also been
        implemented.

0.004   22 July, 2007
        Fixed infinite recursion triggered by element handlers calling
        $dom_tree->write($html)  when  $html contains elements handled
        by the same handler. E.g.,
        <script>document.write('<script>...<\/script>')</script>

0.003   15 July, 2007
      - HTML::DOM::Text now has its nodeValue method, which I forgot
        about before. (Actually, I moved HTML::DOM::Comment's
        nodeValue to HTML::DOM::CharacterData.)
      - as_text and as_HTML have been overridden and now work.

0.002   9 July, 2007
        The basic mechanism for event handling has been implemented.
        The various different flavours of event objects still  need
        to be added.

0.001   27 June, 2007
        The first version. So far, most of the level-1 core DOM is
        implemented,  and a couple of HTML-specific  methods,  but
        that's all.
