Techniques for matching services of a first server with a second server include storing for a translator process transformation rules. The transformation rules transform between hierarchical elements of messages formatted for the first server and hierarchical elements of messages formatted for the second server. When a first message formatted for a particular server of the first server and the second server is received at the translator process, it is determined whether a first element in the first message is associated, in a cache of elements already transformed, with a second element for a second message formatted for a different server. If it is determined that the first element is not associated with the second element in the cache, then the second element is generated using a first rule of the transformation rules. The cache saves substantial processing in messages formatted with a markup language.
