Q: – What Is XML?
XML is a way to represent structured data. Just like HTML, XML uses tags to enclose each piece of data. Unlike HTML, however, with XML you pick the names for each tag so that they are appropriate for your own dataset. One big advantage of XML is that the data contained in XML files is “self-describing,” because each data element is enclosed in HTML-like tags that give contextual clues about the data.
Q: – What Is XSL?
The eXtensible Stylesheet Language (XSL) is used to transform XML files into HTML, new and differently formatted XML files, text files, or other formats.
