What's the regular expression to grab a block of XML between two elements that's contents span multiple lines?

I have the following XML configuration in a pom.xml that's used by Maven.

            <plugin>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.0.2</version>
                <configuration>
                    <dependentWarExcludes>
                        **/hibernate.cfg.xml,**/sql-map-config.xml,**/web.xml,WEB-INF/classes/META-INF/**
                    </dependentWarExcludes>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.appfuse</groupId>
                <artifactId>maven-warpath-plugin</artifactId>
                <version>1.0-m5-SNAPSHOT</version>
                <extensions>true</extensions>
                <executions>
                    <execution>
                        <goals>
                            <goal>add-classes</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <warpathExcludes>
                        applicationContext-resources.xml,ApplicationResources*.properties,ehcache.xml,
                        hibernate.cfg.xml,jdbc.properties,log4j.xml,mail.properties,**/persistence.xml,
                        sql-map-config.xml
                    </warpathExcludes>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>appfuse-maven-plugin</artifactId>
                <version>${appfuse.version}</version>
                <configuration>
                    <genericCore>${amp.genericCore}</genericCore>
                    <fullSource>${amp.fullSource}</fullSource>
                </configuration>
            </plugin>

I'm writing a custom program to parse this file and remove the <plugin> block for the "maven-warpath-plugin".  

The following regular expression works, but it grabs all the XML until the last "</plugin>" in the file - rather than just the next one.

<artifactId>maven-warpath-plugin</artifactId>(?s:.)*</plugin>

Any ideas how to change it so it doesn't match the last one, just the next one?  Also, I'd like to capture the XML preceding the <artifactId> referenced in the pattern above?

I'm using Java and Ant's ReplaceRegexp Task (http://ant.apache.org/manual/OptionalTasks/replaceregexp.html) to do the find/replace logic.

Thanks,

Matt
