specifying the encoding attribute explicitly

[John Hopper]

Hello,

Using code below to create an xml file, how do I specifiy utf-8 encoding in
the root element, ie create "<?xml version="1.0" encoding="utf-8"?>

Thanks!

-------------------------------------------

Dim xmlWriter As New
XmlTextWriter("C:\inetpub\wwwroot\rss2\20061019\te st.xml", Nothing)
xmlWriter.Formatting = Formatting.Indented

With xmlWriter
.WriteStartDocument()
.WriteStartElement("rss")
.WriteAttributeString("version", "2.0")
.WriteStartElement("channel")
.WriteElementString("title", "caseNumber" & ": " & "caseName")
.WriteElementString("link", "link")
.WriteElementString("description", "caseName")
.WriteElementString("lastBuildDate", Now.ToString("ddd, dd MMM
yyyy hh:mm:ss") & " GMT") '<<<<<<<<<<<<<<<<<<<<<<<<<<<
'.WriteElementString("pubDate", caseAdded.ToString("ddd, dd MMM
yyyy hh:mm:ss") & " GMT") 'Now())
.WriteStartElement("item")
.WriteElementString("title", "description")
.WriteStartElement("guid")
.WriteAttributeString("isPermaLink", Nothing, "false")
.WriteString(Guid.NewGuid.ToString)
.WriteEndElement()
' .WriteElementString("title", description)
.WriteElementString("description", "caseNumber")
.WriteElementString("link", "link")
'.WriteElementString("pubDate", dateModified & " 12:00:00 GMT")
'Now().ToString) <---------------------------change
.WriteElementString("pubDate", Now().ToString("ddd, dd MMM yyyy
hh:mm:ss") & " GMT")
.WriteEndElement() '<<<<<<<<<<<<<<<<<<<<<
.WriteEndElement()
.WriteEndElement()
.WriteEndDocument()
.Flush()
.Close()
End With
xmlWriter = Nothing

Hi John,

I don't think <?xml version="1.0" encoding="utf-8"?is actually
supposed to be part of your XML document. Doesn't this XML directive
automatically get created by whatever mechanism you are using to
transmit the XML?

Usually, this is set by the content-type property (MIME type) of
whatever is actually performing the transmission.

Also, using the code below, I can't open the resulting xml file in IE7.0 and
it won't validate at www.feedvalidator.org unless I open it first in notepad
and then save it back. I make no changes to the file, I simply open and then
close it using notepad and then it validates in both. The file (before
opening/saving in notepad) will work in various rss readers, however, without
any error. Any ideas? Thanks!

I see now that this can be declared as a parameter of the constructor.

Well, I know that MS Notepad processes carriage returns and line feeds
differently than MS WordPad. I've seen this in UNIX generated files
that are opened in Notepad - all the line breaks are lost and instead
display as unprintable characters. But, when you open the same file in
MS WordPad, the line breaks are processed correctly.

I suspect that notepad just writes an ASC(13) carriage return for each
line break rather than the line feed/carriage return ASC(13)ASC(10)
combination (or is it the other way around?). When you save your file
in MS Notepad, the line terminator that is compatible with your other
applications is substituted into each of your file's original line
terminators that aren't compatible with your other applications.

BTW it could also be that the sequence of the terminator characters is
causing the problem (ie 10 followed by 13 or 13 followed by 10)

See the documentation
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemXmlXmlTextWriterClassctorTopic3.asp>
you need to pass in the encoding e.g.
New XmlTextWriter("C:\inetpub\wwwroot\rss2\20061019\te st.xml",
System.Text.Encoding.UTF8)

you can also check this:

xmlWriter.WriteProcessingInstruction("xml", "version='1.0' encoding='UTF-8'");

In that case there is no need to use
xmlWriter.WriteStartDocument()
