title: Liquibase - Rolling back a set of changesets
body: <p>We do database releases which are made up of a group of change sets and our database change logs are organised in the following way</p>
  
  <pre><code>   MasterChangeLog.xml
  
             ---&gt; Release0001.XML
                      ---&gt; AddCustomerTable.XML
                      ---&gt; AddOrderTable.XML
  
             ---&gt; Release0002.XML
                      ---&gt; AddNewColumnsToCustomerTable.XML
                      ---&gt; AlterOrderTableXML
  
             ---&gt; Release0003.XML
                      ---&gt; AddPreferedCustomerTable.XML
  </code></pre>
  
  <p>I would like to know how I would go about rolling back a set of change sets. I was hoping that I could use tagDatabase with the release number (Release001, Release002 or Release003) and just roll back using the tag</p>
  
  <p>I would expect to be able to do something like this if I wanted to rollback all change to Release001</p>
  
  <pre><code>java -jar "liquibase.jar" --changeLogFile="MasterChangeLog.xml" Rollback "Release0002"
  </code></pre>
  
  <p>Could you please tell me how I would go about getting this to work with Liquibase?</p>
  
  <p>Thanks</p>
