Hi,
I am having some problems with the XmlTextReader class.
In the code [1] below, I have two Methods 'Run' and 'GetXml' apart from the
Main.
The 'GetXml' Method reads an xml file [3], read a couple of nodes from the
xml and returns the XmlTextReader object.
The returned XmlTextReader object is then passed to the Run Method, which
also does the same iteration over the nodes.
See the source [1]
The confusion begins when I saw the output [2] which demonstrate that the
XmlTextReader object in the 'Run' Method
starts reading from where the XmlTextReader object left in the 'GetXml'
Method.
Is there any way I can reset the state of the XmlTextReader object in the
'Run' Method?
Or some other solutions may be:
a) I have to read the xml file again in the 'Run' Method?
b) XmlDocument should be used instead of XmlTextReader in the 'GetXml'
Method?
-maybe there is something very simple that I am missing here
