Hi,

I receive XML document from input and I would like to read it several
times...
My declaration is
XmlTextReader XMLInputReader =
new XmlTextReader(fileImport.PostedFile.InputStream);

I am reading it like this

while (XMLInputReader.Read())
{
//code
}

After this loop I am at the end of XMLInputReader but I would like to be at
the beginning of that reader because I need to use that loop for reading
again...
How can I make it?

Thanks for your responses...

XmlTextReader is a fast forward only pull parser.
If you want to navigate back and forth then an XPathDocument
respectively an XPathNavigator created from that can help.

Martin, I will try to look at it...

still one more question... I tried to create another XMLTextReader object
and simply put the content of old one to this new one. But I need copy of
whole content. So in that case I can read from both readers from the
beginning. Could you advice how to make it?

Something like this:
XmlTextReader XMLInputReader =
new XmlTextReader(fileImport.PostedFile.InputStream);

XmlTextReader XMLInputReader2 = XMLInputReader;

but it should also work...

thanks

Isn't PostedFile.InputStream a reusable stream? Can't you just create
anothe reader the same way?
If no - read the whole PostedFile.InputStream content into temporary
MemoryStream and reuse it.
