Re: DOM APIs - XML to SVG parsing

Hi Jeff,

I don't have a problem getting the XML file and working with its
elements and strings. What is needed is a seamless way to take the xml
element string and plant it as an  svg element in the SVG document.
Similar to Adobe's parseXML() function.

Regards,
Francis
