| |
| <p> |
| DVSL (Declarative Velocity Style Language) is a tool modeled after |
| XSLT and is intended for general XML transformations using the |
| Velocity Template Language as the templating language for the |
| transformations. The key |
| differences are that it |
| incorporates easy access to Java objects and allows you to use |
| the Velocity template language and it's features for expressing the |
| transformation templates. |
| </p> |
| |
| <strong> Similarities to XSLT</strong> |
| |
| <p> |
| DVSL steals two of the best features of XSLT: |
| </p> |
| |
| <ul> |
| <li> |
| It uses a declarative syntax like XSLT. |
| </li> |
| <li> |
| Document control and selection is based on XPath. |
| </li> |
| </ul> |
| |
| <strong>Differences From XSLT</strong> |
| |
| <p> |
| DVSL differs from XSLT in a few ways |
| </p> |
| |
| <ul> |
| <li> |
| DVSL's template language is Velocity, so conventional Velocity syntax is |
| used to get and set data, to perform looping and flow control, etc. All |
| features of VTL are available. |
| </li> |
| <li> |
| Because DVSL is based on Velocity, it offers a very tight binding to |
| Java objects. This means that it's easy to access other data sources |
| from within the DVSL stylesheet, using conventional method call syntax, |
| allowing you to integrate, collect, and |
| transform with and to outside data like databases, calculation libraries, etc |
| </li> |
| </ul> |

| DVSL is now mature and usable in production environments. |
