Is Learning XML useful to a web developer?
821392
XML is useful in several ways to a web developer.\n\nFirst of all, by learning its syntax rules and coding XHTML instead of HTML you can achieve faster page rendering on the client side -- XHTML is much more picky than HTML, which makes the code more consistent for the browser and faster to load.\n\nSecondly, XML can be used in the back end as a general purpose and very flexible storage medium. Since it is a developed standard, all the languages you care to use these days support it. PHP, Python, the C family, Perl, Java and Ruby are all happy to use XML data. This way you may have special purpose scripts for administration or garbage collection written in a different language but using the same data files. (Of course, you can also store the information in a relational database; XML works better than a relational system if the data schema in each record might be different.)\n\nLastly, familiarity with XML will help with transitioning to making AJAX-enabled dynamic page designs, with nice features like fields that auto-complete with guesses and page designs that can update at any time -- not just when a page reloads.

XML (Extensible Markup Language) is a subset of SGML (Standard Generalized Markup language.)  XML helps data be served, received, and processed on the web because XML describes data in a very specific, ordered, and hierarchical way.  XML is described and maintained by the W3C (the same organization that defines HTML) and is now in version 1.1.  You can read more about XML at \nhttp://www.w3.org/TR/xml11/\n\nHere's an example of a snippet of xml\n\n<library>\n  <book>\n  <title>Green Eggs and Ham</title>\n  <author>Dr. Seuss</author>\n  <pages>28</pages>\n  </book>\n  <book>\n  <title>Dune</title>\n  <author>Frank Herbert</author>\n  <pages>779</pages>\n  </book>\n</library>\n\n\nFor more info on RSS, I'd read "What is RSS" from Xml.com authored by Mark Pilgrim ( http://www.xml.com/pub/a/2002/12/18/dive-into-xml.html )

So many possibilities...\n\nWhile pursuing development will always provide some benefit, I would encourage you to stick with areas where you're already strong, and just learn development as a means to enhance your content options.  I personally believe there will always be opportunities for experienced designers, although the format may develop more over time.  The bubble is still recovering, but its fairly obvious that the web is here to stay, web applications are on the forseeable horizon and will it likely will evolve into something better over the next few years.\n\nHave you looked at Microsoft Expression yet?  I'm not sure if there are any competitors for it, but I feel that it is a good step in the right direction.  As content delivery becomes ubiquitous more applications that focus on a variety of content delivery options (instead of just a web browser) will become the norm.  This is where the design experience will pay off.  As web applications become more pervasive for the consumer, there will be a greater need for experienced designers to present it well.\n\nDon't give up the ghost yet.  I would wager that the "bubble burst" was just a twitch in the growing pains of the Internet.  The best is yet to come...:).

I agree with #1 and will expand...\n\nYour portfolio is likely to get you the job or project before   any certification will. Degrees and certifications for Web development are relatively new, and most very good developers learned the trade before certifications were available.

Javascript is a good language to learn if you are going to be any web development, especially with AJAX becoming such a strong part of the web, but you should not expect to learn javascript alone and be able to do a whole lot.  \n\nIf you are going to do web development, you really need to couple javascript with a server-side language like ASP, JSP, or PHP.  That's where the real stuff happens.  Javascript can only do so much.

XML was designed to describe data and to focus on what data is.\nHTML was designed to display data and to focus on how data looks.\n\nThis is the Simple difference ...

XMLHTTP: Super Glue for the Web\nBy Kyle Patrick \nIntroduction\nMost ASP developers have at least fiddled with the new XML support that Microsoft has shipped with their latest browsers. Hopefully, some of you have found clever ways to use Extensible Markup Language (XML) to enrich your Web sites. Yet, using only XMLDOM might give one the feeling that something is missing. After all, XML is meant to be used as a data representation and exchange format on the Web, and while it can be used quite satisfactorily to represent data, developers are still forced to rely on Common Gateway Interface (CGI) for data exchange between the browser and server. CGI, of course, offers absolutely no freedom in the form of communication, so it is fairly useless to use with XML. Luckily, Microsoft has provided a much better method to transfer XML, which has gone largely unnoticed. \nIn the suite of objects that Microsoft packaged with their MSXML parser, perhaps none are more useful or more ignored than the XMLHTTPConnection object. In a very simple sense, it allows one to open an HTTP connection to a server, send some data, and get some data back, all in a few lines of script or code. The data exchanged through the XMLHTTP object is usually XML, but this is not a requirement. \n \nDown to Business\nThe standard model for this type of interaction would be for the client to send a string of XML text to the server, the server loads the string into an XMLDOM object and parses it, then returns either HTML for the client to display, or another XML string for the client to load into an object and interact with. This serves as an effective form of information transfer, especially when used with Dynamic Hypertext Markup Language (DHTML) to allow dynamic display of the returned information. For example, (this will only work with Internet Explorer 5.0 on the client and server):

Web Design is a very broad subject. It is very much worth learning as a skill to have but in order to be of value in the industry you need to learn a fair bit. \n\nConsider the page design and layout just one part of it. You will need to think about what coding langauges you wish to learn, HTML, PHP etc. \n\nIf you want to create scripts to automate things then you may need to learn Perl, ASP. \n\nIt is very rewarding to create a site and get it functioning correctly on your own accord so even if it's going to be a hobby I would say yes, give it a go.\n\nThe 'for dummies' books are great to get started.

get the ORielly book XML & Java. Its really amazing and in depth. Lots of places you can download the EBook as well

XML is not a programming language, but more like a technique for structuring and describing what data is. All data can be structured in XML. Here is an example below...\n\n<?xml version="1.0" encoding="ISO-8859-1" ?> \n<CAR>\n<WHEELS>4</WHEELS>\n<COLOR type="metallic">Pink</COLOR>\n</CAR>\n\nThis describes a metalic pink car with 4 wheels. Given this, XML is for data that could be part of a document. \n\nXHTML is standard HTML that follows the rules of XML. XML is designed in a way to be very structured. HTML is not. XHTML is just "eXtensible" HTML that follows the XML ways and allows you to define your own tags (like we did with car in the example above.\n\nI have included some links to help you get started on understanding it better... I also recommend you pick up a book like XML from Visual Blueprints. I have included a link to that as well. \n\nGood luck!

XML is an extensible way to format files for parsing. It's just a file format. So, unless you're using it for something specific, I'd say it has no impact at all.

Sorry, but if you want to use web services, it is your obligation to understand and obey all the rules stated in the terms of service. I have found most of them pretty easy to understand if you just take the time to read them, which can be very important to do.

When it comes to langauages (like php or html) dont think in terms of good or bad. Think in terms of functionality. You need to look up the uses and environments for php and html ... in otherwords do you hoemwork yourself!

Yes, it's good to learn them. Because any Tom, Dick and Harry can download and learn them they're alot more diverse and alot more people know them. That puts you at a disadvantage if you DON'T know them. Keep your ABAP skills sharp, but learn JDeveloper or J2EE as well. It'll keep you competetive on the market, and give you a new look at programming.

presumably a language with inherent XML support\n\nI would steer clear of .net since its idea of XML is non-standard (ms specific in most areas)\n\njava 1.5 fully supports XML parsing and generation, the real advantage here is its cross platform support\n\nRuby is said to be make the most logical sense syntactically , so I would suggest this language. If portability isn't an issue.\n\nPHP's latest incarnation is said to be very powerful, however I don't see any distinct advantages in using it

wont cost much if your willing to learn HTML
