NAnt issue - unsuccessful in using xpath expression with xmlpoke

[chrisjaycomer]

I have successfully setup numerous xmlpoke statements within an Nant
script but this specific situation I cannot figure out. I am including

a section of the xml code I am trying to access and update using an
xmlpoke statement. No matter what I try I continue to get "
[xmlpoke] No matching nodes were found with XPath
expression '/log
gingDistributor Configuration/xmlSerializerSe ction/enterpriseLibra ry.logging**Dis tributorSetting s'.

Below is the error message, xml file I am trying to modify and the
corresponding xmlpoke expression which fails.
Error Message

There is a default namespace, that's why the xpath returns nothing.

Tasos thank you for your reply.

Actually I may have not been clear enough in my original posting. What
I ultimately want to alter is the filename attribute under the sink
element as posted below. Is this something you could help me with?

<sink xsi:type="FlatF ileSinkData" name="Flat File Sink"
fileName="LPM_l og.txt" header="" footer="" />

<enterpriseLibr ary.loggingDist ributorSettings defines a default xmlns
thats why the xpath query does not return a node.

What you should do is to create an xpath query based on the local name
of the node you are searching (as I dunno any way you could specify a
default namespace).

I had the same issue (code wise) with the configuration files of the MS
App Blocks and I used string replace :) .
