My application has a base XML file that gets transformed into browser friendly format, or into "Prince friendly" format. My code:
Dim strXmlFile As String = Server.MapPath("IntegratedView\ovIV-" & Request.QueryString("d") & ".xml")
Dim strXslFile As String = Server.MapPath("IntegratedView\VisionPrint.xslt")
' Load our XML file into the XmlDocument object.
Dim myXmlDoc As XmlDocument = New XmlDocument()
myXmlDoc.Load(strXmlFile)
' Load our XSL file into the XslTransform object.
Dim myXslDoc As XslCompiledTransform = New XslCompiledTransform()
myXslDoc.Load(strXslFile)
' Create a StringBuilder and then point a StringWriter at it.
' We'll use this to hold the output by the Transform method.
Dim myStringBuilder As StringBuilder = New StringBuilder()
Dim myStringWriter As StringWriter = New StringWriter(myStringBuilder)
' Transform the XML file using the XSL stylesheet
myXslDoc.Transform(myXmlDoc, Nothing, myStringWriter)
' Process the transformed XML thru Prince to create PDF
Dim xmlPrint As Prince = New Prince
xmlPrint.SetLog(Server.MapPath("VisionPrint.log"))
If xmlPrint.ConvertString(myStringWriter.ToString(), Response.OutputStream) Then
Response.ContentType = "application/pdf"
Else
Response.Write("<html><body><h2>Error generating PDF</h2></body></html>")
End If
I get no log, just the error. For verification, I removed the prince section and replaced with
Response.Write(myStringWriter.ToString())
The code ran. Did a view source, saved to disk, and ran that thru Prince application and it converted perfectly.
So, am I missing something really simple (I hope)??? :shock:
