Problem getting node

I'm having a problem in by 2005 application. When i try to get a node 
from my app.config file the node come back with "nothing". The xmldocment 
loads OK, but I can't retrive a node. The app.config file is listed below 
and the code is listed below that, the line with "-->>" is where i try to 
get the node. Can anyone see where I'm going wrong.

A dump of the xmlDocument is listed below the code.

Note: "MyKey" is set to "Reports"


App.config file
<?xml version="1.0"?>
<configuration xmlns="">
    <add name="My.MySettings.DataConnectionString" 
Source=C:\Ingredients_Data.mdb" providerName="System.Data.OleDb" />
    <add key="Reports" value="C:\current\Reports.xls" />

Hi John

The problem I believe lies in the fact that your XML falls under the
default namespace

And your xpath expression is not namespace aware.

That is why your Xpath expression doesn't work as you hope - i.e
XmlNode =
& MyKey & """]")

i.e this always sets XmlNode to null

A quick work around would be to remove the namespace from your Xml to
get your code rolling and xpath working.

- however as has been quoted elsewhere on this group
"Changing the XML to remove xmlns is usually not the right way to solve
the problem but rather an attempt to circumvent the problem."

For more info on namespaces & xpath in .NET read:

Getting Type to Take the Shape of Circles, Autoshapes
I am trying to get type (say a paragraph or two of 9-point type) to take the inside shape of a circle, oval, or other Autoshape. It seems that I was easily able to do this a couple of years ago. I recently added CenoPDF to Microsoft programs and I am wondering if this somehow took away my ability to do this, though CenoPDF has nothing to do with what I am trying to do as related to this question. At present, the type will only take a square or rectangular shape in a circle or other Autoshape. Thanks for any help anyone can give!!! See if the Word Art function is what you us...
