XML- Appln parsing vs Translator/Mapper

By r_balaji ·
We are trying to figure out an XML architecture for our IBM mainframe applications. Most of them are in COBOL. We are planning to do these programs in Java in the long term. The first problem we have is in finding parsers for COBOL. The other problem is in understanding XML implementations. What are the advantages of parsing XML in programs (either Java or COBOL) as opposed to tranforming them to flat file formats using a middleware product like Mercator/MessageBroker/MQ Integrator ?

Any XMLimplementation experience would be good feedback.

XML- Appln parsing vs Translator/Mapper

Hi,

We are also looking at the same thing but we do not believe that parsing at the program-level is a sound choice because it creates dependencies and raise the Total Cost of Ownership too much for these legacy systems, which are quite sensitiveto any kind of modifications.

A message broker approach seems more appropriate (e.g. SagaVista, MQSI, etc.) since we not only translate, but we could also transform the data elements into something more relevant than plain XML translation. The transformation phase could also produced XML output and then be reused with any XML-compliant applications, on any platform.

As for COBOL parser, I personnaly don't believe that they will eventually exist. Better bet on installing Java support under the mainframe and then use a Java-based parser.

Hope this help a little bit.
