RE: XPathNavigator SetValue wipes out XmlType

Hi Noremac,

Please see following document:

#Modify XML Data using XPathNavigator
http://msdn2.microsoft.com/en-us/library/zx28tfx1(VS.80).aspx
Specifically, if the child elements or attributes of an element are
inserted, updated, or deleted, then the validity of the element becomes
unknown. This is represented by the Validity property of the element's
SchemaInfo property being set to NotKnown. Furthermore, this effect
cascades upwards recursively across the XML document, because the validity
of the element's parent element (and its parent element, and so on) also
becomes unknown.



When you changed the first element's attributes, its SchemaInfo.Validity
becomes NotKnown; and the XmlType will need Validity with Valid value to
return the correct type.

To fix this, you need to call XmlDocument.Validate again after you changed
the element's attributes.


Hope this helps.


Sincerely,
Walter Wang (wawang@xxxxxxxxxxxxxxxxxxxx, remove 'online.')
