Transforming Messages with XSLT Filters

You can apply XSLT transformation rules to a web service end point. This enables fine-grained control of web service requests and responses. You can apply multiple XSLT rules to a web service end point method, and you can configure the order in which you apply the transformations.

You can apply transformation rule to a SOAP request or response.

Before revising an application to apply transformation rules, evaluate the pros and cons of doing so: Applying XSLT can lengthen processing time for a web service. In other cases, XSLT makes sense, for example if a web service is exposed to partners with different XML data exchange formats or different security requirements. In such cases, transformation rules can act as a proxy for the web service and be advantageous.

To add a transformation rule to apply to a web service operation with Admin Console, select Web Services > web-service-name | Transformation. Click Add. Admin Console displays a list of transformation rules available for the web service endpoint. To add a new transformation rule, click Add, and then browse to the location of the XSLT file that contains the transformation rule.

To enable a transformation rule, in the Transformation Rules page select the check box corresponding to the rule, then click Enable. To disable the a rule, click Disable.

If you add multiple transformation rules for a web service endpoint, the transformation rules are applied in the order in which they are added.

To remove a transformation rule, in the Transformation Rules page select the check box corresponding to the rule, then click Remove. This removes the transformation rule from the list and removes the corresponding XSLT file.

Additionally, you can create, delete, and list transformation rules with the following asadmin commands:

• create-transformation-rule(1)

• delete-transformation-rule(1)

• list-transformation-rules(1)
