LoadXML in XMLDocument

[César A. Fong Espinola]

Hi, a few weeks ago i have prepared a demo that consuming an rss. Our RSS
(www.todopocketpc.com/rss/rss.asp) would be our consumed rss. But when i try
to execute this code in .Net CF

Public Function obtenerRSS(ByVal pistrURL As String) As XmlDocument
Try
Dim xmldoc As New XmlDocument
Dim writer As XmlTextWriter = New XmlTextWriter(App_Path() & "rss.xml",
Nothing)
Dim request As HttpWebRequest = CType(WebRequest.Create(pistrURL),
HttpWebRequest)
request.ContentType = "text/xml"
Dim response As HttpWebResponse = CType(request.GetResponse,
HttpWebResponse)
xmldoc.Load(response.GetResponseStream())
writer.Formatting = Formatting.Indented
xmldoc.Save(writer)
response.Close()
writer.Close()
Return xmldoc
Catch e As System.Exception
MsgBox(e.ToString)
End Try
End Function
Returns me an error i notice this because our site has this encoding for
being a spanish web site is <?xml version="1.0" encoding="ISO-8859-1" ?>
For my test i have to create another page without the tag encoding and of
course i have to parse and omitted the accented characters and some signs.
is this a bug for .Net CF or do i have to use another method???

Thanks in advanced

Does your web page return correct encoding in the HTTP headers? I.e. does it
match the one in the xml document?

There is no iso-8859-1 codepage on CF/PPC. If you replace it with UTF-8 you
should be able to use western european characters seamlessly

Thanks Alex for your answer i try using all valid encoding for net cf -ppc
but anyone goes fine..i.e. UTF-8 doesn't support accented lowels... i.e. í
á é ú ó so it seems a limititation por net cf.. because it restricts all
spanish xml sites...

So i have to create my own rss reader without using xmldocument ..... :s

Any comments or do you know if this will be added in next CF service pack?

Thanks in advanced

I might have a solution for you...
If you replace the code in ObtenerRss with :

Dim response As HttpWebResponse = CType(request.GetResponse,
HttpWebResponse)

Dim rdr As StreamReader = New StreamReader(response.GetResponseStream(),
Encoding.GetEncoding(1252))

xmldoc.Load(New XmlTextReader(rdr))

it will load xml without an issue. The question is, how to find the
appropriate codepage. Your server (http://www.todopocketpc.com/rss/rss.asp)
does not return a valid charset in the response headers. This means, you
will need to read response into a byte buffer and use XmlReader to parse a
first PI out of it to get the encoding. Of course instead of parsing you can
just try several differnt codepages
