XSLT stands for XML style sheet transformation and it as XML technology used to transform one XML into another XML or HTML format. XML and XSLT interview questions are commonly asked to Java developers, who happen to use XML in there project and mentioned XSLT as key skill in there resume. 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. So if you are a Java programmer, who have used XSLT or going for a Job interview, where XSLT is a key skill, you better be prepare with some popular XSLT interview questions, In this article, I am sharing my list of XSLT questions, which is collected from internet, friends and colleagues and frequently asked as part of XML Interview questions.
