 > Transforms a file system path into a URI with the file:// scheme. If the path is relative, it is first resolved against the current working directory. 


 


 So, on Windows, put this file as `C:\test dir\path-to-uri.xsl`  


  


 ~~~ 
 
 <?xml version="1.0" encoding="UTF-8"?> 
 
 <xsl:stylesheet exclude-result-prefixes="#all" version="2.0" xmlns:file="http://expath.org/ns/file" 
	 
	 xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
	 
	 <xsl:param as="xs:string" name="path" /> 
	 
	 <xsl:template name="main"> 
		 
		 <xsl:message select="'path=', $path" /> 
		 
		 <xsl:variable as="xs:anyURI" name="uri" select="file:path-to-uri($path)" /> 
		 
		 <xsl:message select="'uri=', $uri" /> 
		 
		 <xsl:sequence select="doc($uri)" /> 
	 
	 </xsl:template> 
 
 </xsl:stylesheet>

 and verify that it works with a very simple relative path: 


 


 ~~~ 
 
 C:\test dir>dir /b path-to-uri.xsl 
 
 path-to-uri.xsl 

 

 C:\test dir>java -cp saxon9ee.jar net.sf.saxon.Transform -it:main -t -xsl:path-to-uri.xsl path="path-to-uri.xsl"

 Looks good. 

 

 But `file:path-to-uri()` fails or returns unusable URI in the following cases:
