[Xmltask-users] Conditional insert based on xpath

[Cool T. B. <tec...@ya...>]

Hi,
   I am currently using <insert> task for deploying my webapp. However sometimes, the context is inserted more than once and I have to perform conditional insert in target. Before inserting, I have to check whether path="/Server/Service/Engine/Host/Context[@path='/doceng'] exists or not. If exists then dont insert otherwise insert. I was looking into "if" subtask but could not able to find any examples. Please find my code below and would appreciate your help.

<target name="deploy_local">
		<echo message="(INFO): Please ensure that server is down, while deploying to localhost"/>
		<xmltask source="${tomcat.home}/conf/server.xml" dest="${tomcat.home}/conf/server.xml">
			<insert path="/Server/Service/Engine/Host/text()[1]" position="before">
				<![CDATA[
					<Context path="/doceng" reloadable="true" docBase="${docBase}">
			           <Resource name="jdbc/docengdb" auth="Container"
			              	type="javax.sql.DataSource" 
							driverClassName="${driverclassName}"
			              	url="${dburl}" 
						  	username="${dbusername}" 
							password="${dbpassword}" 
							maxActive="${maxactive}" 
							maxIdle="${maxidle}"
			              	maxWait="${maxwait}"/> 
					</Context>
				]]>
			</insert> 
		</xmltask>
	</target>
