xmltask provides the facility for automatically editing XML files as part of an Ant build. Unlike the standard filter task provided with Ant, it is XML-sensitive, but doesn't require you to define XSLTs.

Uses include:

• modifying configuration files for applications during builds
• inserting/removing information for J2EE deployment descriptors
• dynamically building Ant build.xml files during builds
• building and maintaining websites built with XHTML
• driving Ant via a meta build.xml to abstract out build processes
