XML/SVG SetAttribute Issue xlink:href 1

[hungerf5]

I'm working on code to generate SVG dynmically via the web. When I try to create an element to display one of the shapes in the <def> section of the SVG file I'm getting unexpected output.

Below I'm trying to create a node called <use> with the following attribute xlink:href.

svgElem = SvgXml.CreateElement("use", "[URL unfurl="true"]http://www.w3.org/2000/svg");[/URL]
svgElem.SetAttribute("xlink:href", "#" + sheetName);
RootNode.ChildNodes[1].FirstChild.AppendChild(svgElem);

XML Output

<?xml version="1.0" standalone="yes"?>
<svg width="800" height="600" xmlns="[URL unfurl="true"]http://www.w3.org/2000/svg">[/URL]
  <def>
    <rect id="13-81X76.5X3.5" x="0" y="0" widht="800" height="600" style="fill:none;stroke:rgb(0,0,255);stroke-width:.05" />
  </def>
  <g transform="translate(20, 585)">
    <g transform="scale(0.95, -0.95)">
      <use href="#13-81X76.5X3.5" />
    </g>
  </g>
</svg>

Notice the code is outputting:

<use href="#13-81X76.5X3.5" />

I expected to see:

<use xlink:href="#13-81X76.5X3.5" />

Why is this happening and how can I get the resluts necessary for the SVG to work properly?

I found a solution but I'm not sure I understand it?

Here code that get the results I'm looking for:

svgElem = SvgXml.CreateElement("use", "[URL unfurl="true"]http://www.w3.org/2000/svg");[/URL]
svgElem.SetAttributeNode("href", "[URL unfurl="true"]http://www.w3.org/1999/xlink");[/URL]
svgElem.Attributes["href"].Value = "#" + sheetName;
svgElem.Attributes["href"].Prefix = "xlink";
RootNode.ChildNodes[1].FirstChild.AppendChild(svgElem);

Here is the XML:

<?xml version="1.0" standalone="yes"?>
<svg width="800" height="600" xmlns="[URL unfurl="true"]http://www.w3.org/2000/svg">[/URL]
  <def>
    <rect id="13-81X76.5X3.5" x="0" y="0" widht="800" height="600" style="fill:none;stroke:rgb(0,0,255);stroke-width:.05" />
  </def>
  <g transform="translate(20, 585)">
    <g transform="scale(0.95, -0.95)">
      <use xlink:href="#13-81X76.5X3.5" xmlns:xlink="[URL unfurl="true"]http://www.w3.org/1999/xlink"[/URL] />
    </g>
  </g>
</svg>

Yeah it only took me half a day of goggling and piecing together bits of information from here ant there...

Ah, the joys of developing when you don't know what you’re doing...

How can I give myself a star?
