Hi,
I am SCJP and going to USA on H1 visa. Somebody told me to learn the XML as it is going to be very popular in USA. Can anybody confirm me about this?
I am new to XML and I have 1/2 months before joing my new job in USA. How much time I need to learn XML and what is the practical assignment I should do?
Bye
Noor

Yes, I have seen XML used a lot here in the USA. In fact, in three different jobs in the last 2 1/2 years I have used XML at least to a certain extent. However, how XML is used varies widely. Some places use XML to transfer data between different applications, some use it for their document management and presentation systems, etc. Therefore it is not easy to tell you what you should learn. However, the basic concepts of XML are quite trivial, there really isn't much to it; it is simply a convenient, platform-independent and human-readable way to represent hierarchical data. I would advise you to take a look at the structure of XML documents as well as DTDs (and possibly XML Schema, but I haven't seen this used yet, and you can always learn it later if you do need it). If you are specifically looking for a Java job, you might also want to check out DOM and SAX parsers. You can probably skip XSLT for now and learn it if you need it later.
A good book to learn about XML (particularly in the context of Java, but it also covers general XML) is "Java and XML" from Brett McLaughlin. Reading the first few chapters should not take more than a day or two and give you a good overview.
