Question

I would like to know the file creation/modification date of the XML file currently being processed by my XSLT code.

I am processing an XML file and producing an HTML report. I’d like to include the date of the source XML file in the HTML report.

Note: I am using C# .NET 2008 and using the built-in XslCompiledTransform class. I have since found a solution (separate answer) using input from other answers here. Thanks!

After suggestions from Kaarel and Robert, I was able to reach the following solution:

Get the file modification date in C# and pass it to the XSLT processor as follows:

XmlTextWriter tw = new XmlTextWriter(htmlPath, null); tw.Formatting = Formatting.Indented; tw.Indentation = 4;  XsltArgumentList args = new XsltArgumentList(); FileInfo fi = new FileInfo(xmlPath); args.AddParam('FileDate', string.Empty,    fi.LastWriteTime.Date.ToShortDateString());  XslCompiledTransform xslt = new XslCompiledTransform(); xslt.Load(xsltPath); xslt.Transform(xmlPath, args, tw); tw.Close(); 

Then in the XSLT code, define and access that argument as a param as follows:

<xsl:param name='FileDate'/>  <xsl:text>Revision Date: </xsl:text> <xsl:value-of select='$FileDate'/>
