Hi,
Does anyone know how to serialize an XPathNavigator object?
I have tried the following but it moans that the xpn does not have a parameterless
constructor.
XPathNavigator xpn = e.Source.Select SingleNode("/ns1:Invoice/ns1:InvoiceDeta il/ns1:Lines/ns1:Line/ns1:Matches/ns1:Match/ns1:SubLedger",
this.NamespaceM anager);
XmlSerializer x = new XmlSerializer(x pn.GetType());
StringWriter tw = new StringWriter();
x.Serialize(tw, xpn);
StringBuilder sbldr = tw.GetStringBui lder();
_tmpXML = sbldr.ToString( );
thanks very much
cheers

What are you actually trying to do? Persist the underlying xml? In which
case, .WriteSubtree(x mlWriter) may help.
If not, can you clarify your intent?
Marc
Or possibly just .OuterXml?
Hi Bruce,
You won't be able to serialize XPathNavigator directly because it's not marked as Serializable.
Why not just serialize the outer-xml of the particular node that you have selected in your example as a string?
If there are particular settings in the XPathNavigator that you want to retain you could create a class that encapsulates those
settings and mark it as [Serializable].

Hi Dave,
Thanks, I will give that a go.
In response to Marc: I need the actual object to be serialized as it is a
reference to a particular element within a repeating group and I have no
way of knowing which instance I am in. (this is using InfoPath 2007).
cheers
Bruce

XPathNavigat or xpn =

this.Namespace Manager);
XmlSerialize r x = new XmlSerializer(x pn.GetType());
StringWriter tw = new StringWriter();
x.Serialize(tw , xpn);
StringBuilde r sbldr = tw.GetStringBui lder();
_tmpXML = sbldr.ToString( );

Hi,
Is the compilation of XSLT, using XPathNavigator.Compile, only beneficial
when the returned XPathExpression is cached?
Next question, how do I cache the returned XPathExpression object? Should I
programmatically cache it or is it automatically cached when the Compile
method is called?
Thanks

Is there an easy way to get the schema's data type for a XPathNavigator value?
I need to be able to determine the data type for the xml value based off of

been able to figure out how to get the data type by reading through a
validating reader, but I can't seem to find an easy way to get this when
using XPath expressions.

Is there a way from an XPathNavigator object to get an xpath string that

return the same XPathNavigator?
In other words, I initially create an XPathNavigator for my entire xml
document. To get an XPathNavigator object who's root is a given node in the
original xml document, there is a unique xpath that will return that node.
The unique xpath could have,...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
