my simple svg document template looks like this: <?xml version="1.0" ?> <svg xmlns="http://www.w3.org/2000/svg"; xmlns:xlink="http://www.w3.org/1999/xlink";> </svg> this way it should work in any svg viewer. you dont need a doctype ;) > > Another one, clarity: You look at some code and you think you > perfectly know what it's doing.

Note the extra node 0 and the > concatenated old and new text of the tspan's. the reason for this behavior is that there are many node types in xml. there are: ELEMENT_NODE = 1; ATTRIBUTE_NODE = 2; TEXT_NODE = 3; CDATA_SECTION_NODE = 4; ENTITY_REFERENCE_NODE = 5; ENTITY_NODE = 6; PROCESSING_INSTRUCTION_NODE = 7; COMMENT_NODE = 8; DOCUMENT_NODE = 9; DOCUMENT_TYPE_NODE = 10; DOCUMENT_FRAGMENT_NODE = 11; NOTATION_NODE = 12; and childNodes() gets all nodeTypes,not only element nodes try this: for (i=0; i<len; i++) alert(nodes.item(i).nodeType) } in yor original example, and you ll get a sequence of altering 1 and 3 that means you are iterating over element nodes and text nodes. hope that helps Holger p.s.: the complete filemaylook something like this: <?xml version="1.0"?> <svg onload="replacetext(evt)" > <script><![CDATA[ function replacetext(evt) { svgns="http://www.w3.org/2000/svg"; nodes=window.svgDocument.getElementById("sampletext").getElementsByTagNameNS(svgns,"tspan") len=nodes.length; for (i=0; i<len; i++) nodes.item(i).firstChild.data="node "+i; } ]]></script> <text id="sampletext" y="20"> <!-- test --> <tspan x="5" dy="1em">line 1</tspan> <tspan x="5" dy="1em">line 2</tspan> <tspan x="5" dy="1em">line 3</tspan> </text> </svg> ----- To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ---- Yahoo!
