NAnt task example – XmlPokeExtendedTask

NAnt has a XmlPoke task, which is good, but unfortunately it does not create the node if it does not already exists. I have created my XmlPokeExtendedTask which would create xml node with and the spcified attribute for me.

For example

/configuration/appSettings/add[@key='Some.Setting']/@value,10 /configuration/appSettings/add[@key='Some.Setting2']/@value,Low

the ouput XML will contains the following:

<configuration> <appsettings> <add key=”Some.Setting” value=”10″> <add key=”Some.Setting2″ value=”Low”> </appsettings> </confugration>

Here is the assembly and an example. Simply putting the dll into the NAnt folder would work because NAnt automatically include assemblies that are named *Tasks.dll.

NAnt task example – Update database

NAnt is a .Net build tool (which obviously similar to Ant). We have been using NAnt to create and deploy patches and I have been creating my own NAnt tasks to do the job. Recently I am thinking of enhancing the script that I have written couple of years ago.

Each user defined task has a TaskName, maybe some TaskAttribute too, and override ExecuteTask method. Let me just post an example of user defined task here.
