Ten Predictions for XML in 2007 71

An anonymous reader writes "2007 is shaping up to be the most exciting year since the community drove off the XML highway into the Web services swamp half a decade ago. XQuery, Atom, Atom Publishing Protocol (APP), XProc, and GRRDL are all promising new power. Some slightly older technologies like XForms and XSLT are having new life breathed into them. 2007 will be a very good year to work with XML."

      There's one reason I like JSON way more than XML, and its name is RSI.

      If you're getting RSI from XML, you're not doing it right. Use a tool! Anyway, the real reason to use JSON instead of XML is cross-site security restrictions. You can't make an XmlHTTPRequest call from one domain to another, but you can add a <script /> tag with a src pointing somewhere else.

        So, you're saying that in order to use a markup language whose primary design goal was to be easy for human beings to work with, I should invest in buying and learning at tool? Never mind that I have never even seen a decent XML editor.

        Sorry, but XML is just bad design: it's badly designed for machines, and it's badly designed for humans. Using tools to deal with it may be a workaround, but it's certainly not "doing it right".

        In fact, the best compromise is probably simply not to write code in XML, but pick one of the better alternative formats and convert to XML after editing.

          No, I'm saying that you should rarely have to edit XML directly yourself. For the times that you do, use a nice programmer's editor like PSPad or Visual Studio that will automatically add close tags (cut your typing in half!). The rest of the time, you should be generating your XML programmatically from some other data source.

          In fact, the best compromise is probably simply not to write code in XML, but pick one of the better alternative formats and convert to XML after editing.

          Since when is XML "code"? Writing an XSL/T to apply to an XML file may be code-like, but in general XML should be a data format that you pass around between applications, not something you "code" yourself.

            May I suggest JEdit [jedit.org]? It supports XML out-of-the-box and is open source and runs anywhere and is a great* editor by any measure. If after having your XML closing tags auto-completed, indented, and validated effortlessly in this editor leaves XML still too much work for you, then I hope you never use anything beyond Vi, APL, and LaTex.**

          Well said. A good example is RELAX NG [wikipedia.org]: write the source in the compact syntax [relaxng.org] and convert it to XML when/if you need it.

          A simple compact syntax example:

          start = element title { text }*

          The equivalent XML (and the RELAX NG XML format is considered much better than, e.g., W3C XML Schema):

          <grammar xmlns="http://relaxng.org/ns/structure/1.0">
          _ <start>
          _ _ <zeroOrMore>
          _ _ _ <element name="title">
          _ _ _ _ <text/>
          _ _ _ </element>
          _ _ </zeroOrMore>
          _ </start>
          </grammar>

          (Please ignore the underscores.)

          Remember people: XML may be good for data interchange between different applications because every language ever created by the gods has an XML parser, but don't use it for anything else.

          XML is not meant to be easy to "work" with as such, it's meant to be human understandable for things like debugging and development.

            This was out of the XML creators' hands, since the basic syntax was created by the SGML designers, and they designed the syntax with the intent that it be easy to use for humans. Of course, they were wrong.

            In any case, the fact remains that XML is a lousy language for humans and it's a lousy language for computers.

          XML files are NOT "Code", but a methodology of laying out data in a hierarchical [wikipedia.org] format. The human brain structures data in a hierarchical format.

Another thing you can do is think about XML with your brain, but your brain is also a tool.

      You're typing any of this stuff by hand? You're kidding right?

      JSON and XML are appropriate as a wire protocol for app 2 app communication. JSON is appropriate only when the receiving application is written in java script. There are only two scenarios that I can think off right off the bat that I might hand type XML. One is a configuration file (e.g. WEB-INF\web.xml) and the other is a GRDDL [w3.org] style personal vanity site which isn't going to be that much more typing than HTML.

          If they are advertising a job that indicates "Experience with XML", they are going to get shit for replies.

If the company actually wants DOM, XPath, and XSL, they need to say "Experience with XML; experience with XPath, DOM, and XSL a plus" or something of that nature.

      SOAP is typed. XML-RPC isn't. So SOAP is easier to work with in conjunction with stub generators in statically typed languages. Dynamically typed languages are better off with XML-RPC.

      A better comparison is - Is SOAP any better than CORBA for what SOAP is being used for. It was initially sold with the "port 80" and "easier to debug than a binary protocol" arguments. Those don't hold much water any longer. Further, SOAP added a ton of extensions obliterating any ease of use promises, a trap that CORBA itself fell into. Heck, even the basic WSDL spec turned out to be difficult enough that stub generators aren't available for most languages. Python recently got one last week, but dynamic languages mostly went without.

      If all that one does is typed stateless procedural calls, CORBA is hardly anymore complex than SOAP and heck of a lot more efficient than SOAP.
