Replacing char

[anonymous]

Hello,

I need to replace this char  with another char.
However I am not able to acieve this. I tried this but it
doesnt work:

str = str.Replace(chr(asc(194)), "")

Can somebody help ?

The "replace" needs either two characters or two strings. In your case, try:

Dim c As Char = Chr(194)
str = str.Replace(c.ToString, "")

Or why not just str.replace("Â", "")?

I tried both versions, but it still doesnt work. The thing
is that I am reading the following rss
(http://pluralsight.com/blogs/dbox/Rss.aspx) and creating
the file with the description of the item. The file
contains only the description with the strange chars. Here
is my complete code:

Dim reader As New XmlTextReader
("http://pluralsight.com/blogs/dbox/Rss.aspx")
Dim xmlDoc As New XmlDocument

xmlDoc.Load(reader)

Dim nodes As XmlNodeList = xmlDoc.SelectNodes
("/rss/channel/item")
dim i as integer = 0

For Each node As XmlNode In nodes
Try
strPost = node("description").InnerXml
Dim c as char = Chr(194)
strPost = strPost.Replace("Â", "XX")
Dim fp As StreamWriter
dim strfile as string = Server.MapPath("xml_news//")
strfile = strfile & i.tostring()
strfile = strfile & ".asp"
fp = File.CreateText(strfile)
fp.WriteLine("<p>" & Server.HtmlDecode(strPost)
& "</p>")
fp.close()
Catch ex As Exception
Response.Write(ex.Message() & "<br>")
End Try
i = i + 1
Next

Thanks for any help.

I don't see any Âs in the feed? Is it really the character you want to
replace?
cheers,

Try my code and you will see that the asp page contains
this character.

I get exceptions when I run your code ("could not find a part of the path"),
but tracing through still don't see the  (e.g. strPost.IndexOf("Â") fails).
Is it possible you have a code page problem?

The A character only appear in the created file. Ofcourse
you need the change the path so that it works on your
system.

Please help.

My dumb mistake on the path. Looks like the source has some nonbreaking
spaces ( ascii 160), which the htmldecode is turning into asc 194. I'm
guessing you could do your replace *after* the decode, else replace on 160
*before* the decode. As to why that space is not encoded, whereas, say, the
<'s are correctly converted to < etc., I don't know. Not sure if that happens
on the rss end, or maybe in your textreader. Anyway, I'm not familiar with
grabbing a feed the way you're doing it, so can't offer much more. Hopefully
this will get you going.

Thanks man. That did the trick. I was replacing 194 before
encoding. Now I am replacing 160 before encoding and it
works like a charm. How did you know that it 160 before
encoding?

Thanks

P.S. There's a good article here you might find interesting:

Its a regular article about consuming rss. I do it the
same way. Thanks

I just looked at the 194's, then went back to those same positions in the
original and found the 160's by dumping the ascii values of those strings. I
had also guessed it might be something with &nbsp's, which is always a decent
bet when something looks ok on the screen but your code chokes on it. Have
fun.

Hey, wasn't regular to me--I learned all sorts of new things from your post,
thanks.
