SignXML.LoadXML failes with unknown transformation

EDN Admin · Jan 26, 2011

I am working with VS 2010 / .NET 4 to implement a simple XMLdSig verification. The signature is created by a webservice provider and out of my control. As far as I could examine, the structure of the signature is valid. Hours of googling gave my the impression
that xmlenc#256 may be a problem, but before that I even cannot load the XML document.
Can anyone help and tell me whats going wrong resp. where/how to find a solution?
Here is my code snippet:
DialogResult rc = oFDXML.ShowDialog();

<span style="color:blue if (rc!=DialogResult.OK)

{

<span style="color:blue return;

}

XmlDocument xdoc = <span style="color:blue new XmlDocument();

xdoc.PreserveWhitespace = <span style="color:blue true;

xdoc.Load(oFDXML.FileName);

XmlNamespaceManager ebMgr = <span style="color:blue new XmlNamespaceManager(xdoc.NameTable);

<span style="color:blue string PrefixURLeb = http:<span style="color:green //www.ebinterface.at/schema/3p0/;

<span style="color:blue string PrefixURLsig = http:<span style="color:green //www.w3.org/2000/09/xmldsig#;

ebMgr.AddNamespace(<span style="color:#a31515 "eb", PrefixURLeb);

ebMgr.AddNamespace(<span style="color:#a31515 "dsig", PrefixURLsig);

SignedXml sXdoc = <span style="color:blue new SignedXml(xdoc);

XmlNodeList nodelist = xdoc.GetElementsByTagName(<span style="color:#a31515 "dsig:Signature");

sXdoc.LoadXml((XmlElement)nodelist.Item(0));

<span style="color:blue if (sXdoc.CheckSignature())

{

MessageBox.Show(<span style="color:#a31515 "Signature OK");

}

<span style="color:blue else

{

MessageBox.Show(<span style="color:blue <?<span style="color:#a31515 xml <span style="color:red version<span style="color:blue =<span style="color:black "<span style="color:blue 1.0<span style="color:black " <span style="color:red encoding<span style="color:blue =<span style="color:black "<span style="color:blue UTF-8
