To be clear for others reading, we don't call that a module descriptor, but a resolution report. A module descriptor cointains metadata about a module (usually an ivy file or a pom), while the resolution report contains much more information about how the resolution of dependencies of a module configuration has been performed. to extract information about the complete list of dependencies, both > names and versions, for an internal process that requires them in a > simple text file.

The search attribute only indicates if the module required a look up in the repository to find it or not. This is usually the case either if your use a dynamic version (latest.integraiton for instance). According to the file extract you provide below, I'd say this is a bug in Ivy, you shouldn't have twice the same revision. I think we end up with twice the revision because during dependency resolution we end up with an IvyNode for this module revision being referenced twice in the nodes map: one for 4.2.0.20071030042610, and one for latest.integration. But we should do a better work when generating the xml, to output this IvyNode only once. So the best is not to solve the problem in your XSLT but in Ivy. Could you open a bug in JIRA?
