دانلود کتاب Sams Teach Yourself XML in 21 Days

I've been in a process of trying to learn XML for quite awhile, and the books to be found on this topic have been frustrating. I'm trying to learn something new, but find difficulty learning from book after book that has so many mistakes. I'm able to learn just enough to realize the mistakes in the book, why something isn't working, and then troubleshoot the XML document I'm putting together.Learning XML is nothing, but producing a VALID document through a Document Type Definition that you must write yourself is harder. You're then learning that process too. Plus..XSL and XSLT..so that the documents are Web usable.I found Sam's Teach Yourself XML in 21 days better than most books I've worked with so far. The book was helpful. I also appreciated the links offered for great software, one of them being Architag XRay for transformations. It beats using Saxon at a command line.If you want to learn XML, this book can help you with some basics. A better book is Real World XML by Steven Holzner.
