Marc, I think you are using svg name space as the default name space in the SVG document you are editing. Well I was doing that and when I added some new elements using DOM methods the output was a right SVG (XML document) but batik didn't recognize the new tags, so I defined the svg name espace: xsl:svgdcs in the document.
xmlns:svgdcs="http://www.w3.org/2000/svg"; set the name space in the java application: xPath.setNamespaceContext(new NamespaceContextProvider("svgdcs",SVG_NS)); and work with the namespace elements in the rest of the code: public void changeLocation(String nameLayer,XPath xPath,AbstractDocumentFragment svgFragment) throws XPathExpressionException{ Node position=(Node) xPath.evaluate("//svgdcs:[EMAIL PROTECTED]'"+nameLayer+"']",svgFragment,XPathConstants.NODE); position.getAttributes().getNamedItem("transform").setNodeValue("translate("+x+","+y+")"); } Best Regards Abraham On Oct 31, 2007 6:52 PM, Marc-Wayne M.
