Well, I've never used xmlpeek - but I do develop XSLT stylesheets, so I
understand XPATH expressions.

The XPATCH expression "/parameters/parameter/name" is working correctly
- both of the parameters are matching.
You need to add some kind of predicate to your XPATH expression to only
match one parameter.
One way is to match based on index, something like this:
> <xmlpeek verbose="false" file="${DB.DBFilePath}"
> xpath="/parameters/parameter[1]/name"
> property="DB.DataFilePath" />
However, this will fail if the your XML file is changed, as it's hard
coded to retrieve the first parameter, no matter it's name.
This might be better:
> <xmlpeek verbose="false" file="${DB.DBFilePath}"
> xpath="/parameters/parameter[name = 'DATA_FILE_DIR']/value" >
> property="DB.DataFilePath" />
Ie: Give me the Value of the Parameter with name 'DATA_FILE_DIR'.
Caveats:
(i) These examples are written of the cuff, so to speak, so they're
completely untested.
(ii) I normally write XSLT for the Apache Xalan XSLT processor; there
may be some differences between it and the MSXML processor used by NAnt.
Hope this helps,
Bevan.
