Given XML’s popularity as data transfer protocol, many systems in middle and back office space uses XML messages to transfer trade details, for example Bookings, Settlement, and Confirmation system uses it as a data exchange protocol. Since each of this system performs some normalization, enrichment and transform on incoming trade message, they use XSLT for those transformation. XSLT is rich, powerful and given it’s support in Java and several other programming language, it comes natural choice of XML transformation. What you need to is to write XSL files, also known as XML style sheet to specify your transformation rule and than XSLT engine will transform each incoming XML documents as per your XSL file. Though, XSLT is rich, it’s can also be very complex for Java programmers, who are used to procedural style of coding, as XSLT uses recursion a lot.

By using SED you can edit files even without opening it, which is much quicker way to find and replace something in file, than first opening that file in VI Editor and then changing it. In this SED command tutorial we will see some practical examples of SED command in UNIX based systems e.g. Linux. I must say having a good grip on find, grep, sort, vi editor and SED can take you next level of UNIX and Linux working experience. These are very powerful UNIX command and helps with lot of different tasks in server. By the way we will use following text file for our SED common example. As I have said before, best way to learn any UNIX command is to use them in your day to day task, and a good example is a good start. This file contains details of some popular android and iPhone smartphones, e.g. Model, company, price etc, separated by colon. You can also use any CSV file for this example.
