Similar to the question here...I have XML that looks like this:\[code\]<image overflow="visible" width="367" height="445" xlink:href="http://stackoverflow.com/questions/12460140/etcetcetc"...\[/code\]All I need to do is set the xlink:href value to something else.Code I've tried so far (just testing getting the 'xlink:href' value):\[code\]XDocument XD = XDocument.Load(Server.MapPath("/svg/") + file);XElement SVG_Element = XD.Root;foreach (var x in SVG_Element.Descendants("{http://www.w3.org/2000/svg}image")){ lblStatus.Text = "Value: " + x.Attribute("xlink:href");}\[/code\]But I get a runtime error: \[code\]The ':' character, hexadecimal value 0x3A, cannot be included in a name.\[/code\]The above code works when I replace \[code\]xlink:href\[/code\] with \[code\]width\[/code\] for example.
