XML as parameter to a method

Tushar

Is it possible to have a method that accepts XML document (including
processing instruction at top and the root node) as a parameter? Does this
parameter need to be defined as type string?

I have been given an XML structure to be used in a method call and I am not
sure if I should convert that into a C# struct to be used as a parameter
type and if so how. The specification says something like ... The input will
be an XML such as ...

<?xml ... ?>
<root>
<etc etc />
</root>

Please help.

Yes, except you can't have the ?xml? PI because there's only one of those allowed per document and the SOAP message is itself a document. You shouldn't need the PI if you think about it.
Does
this parameter need to be defined as type string?
Noooooo, definitely not. Your web method signature need simply be something to the effect of:

public void MyWebMethod([XmlElement("nameOfYourRootElement", Namespace="uri:somenamespaceuri")] XmlElement rootElement)
{
.... use rootElement here ...
}
I have been given an XML structure to be used in a method call and I
am not sure if I should convert that into a C# struct to be used as a
parameter type and if so how. The specification says something like
... The input will be an XML such as ...

<?xml ... ?>
<root>
<etc etc />
</root>

Well everything's ok except for the ?xml? PI. Whoever said that has to be the spec should be questioned about it because they should know that that particular PI isn't allowed to be defined twice and, when it is defined, it must be the first line of any XML document instance. Since the SOAP envelope itself is XML, it already contains this PI. Therefore it should not be needed on your parameter.

HTH,
Drew

One way to do this is to define the parameter as an encoded string. This
isn't optimal since the entire document will be byte encoded on the wire to
get around the angle brackets, etc. This equates to a CDATA region in an
XML schema. Not pretty, not recommended. If you really need to be able to
post an XML document, you might want to just handle the XML directly from
an HTTP filter or an XML data island within a web page.

I hope this helps

Hi Scott,

I only mention this kind of approach because it seems that your
requirements much more closely fit, from what little I know, a traditional
ASP page approach (or plain old HTTP).

Does this make sense?

Ahh. It was a technique for embedding XML islands within ASP pages and
having script on the client side process the XML. It basically had the
server putting XML into a span, and then the script on the client side
reading that XMl and using it to display dynamic content.
