White spaces in XSLT file path when used with XsltCompiler.Compile(filename) throws the following exception:

“Invalid URI for stylesheet: ”.

But if you place the XSLT file in a path with no white-spaces, this succeeds.

Workaround:

xsltInput = processor.NewDocumentBuilder().Build(new Uri("file:///" + xsltPath)) // the xsltPath string must have escaped white space i.e. %20

Investigation:

The problem is in the open() method of the classUseWhenFilter class. Here we make a call to the URI class constructor on the systemID of the XSLT stylesheet. This will fail if the string contains spaces.
