Re: about zooming

2.        doc = rootNode.ownerDocument; It throws both at lines 4 and 13 , showing the following message "Exception: TypeError: doc has no properties". What is missing ? Apparently an owner document... where is rootNode coming from, exactly? Actually, this rootNode comes from here (in bold): ******************************************************************** <quoted> (from a firefox UI file)         //window.content.document is the rootnode         zoomer.zoom (window.content.document, scale); ******************************************************************* zoom: function(node, factor) {             createArrangedList (node);             czZoomElements(node, factor/100); ******************************************************************** Oh no, how dump I am :) ... the rootNode _is_ the on the top, so it _is_ ownerDocument , right :-[ ? But eventhough I got a "no support for Traversal problem", as following: <quoted> ... if (!rootNode.implementation.hasFeature("Traversal", 2.0) ) {             dump ( "A DOM implementation that supports traversal is required.");              return; } iterator = rootNode.createNodeIterator(rootNode, NodeFilter.SHOW_ALL, filteringRelevantNodes, true); ... </quoted> There is no traversal support available. So the iterator is not created. Can I do anything special to get support to it ? regards
