    How to create an XML file

    Preliminary information

    Prima di enter the dettaglio della procedura su how to create an XML file, I think it is important to explain to you what it is, what it is for and what its basic structure is.

    Well, XML is not a programming language (since it is not based on flows of linked actions, nor on a basic algorithm), but a metalanguage for defining markup languages. This last category of languages, does nothing but mark a series of elements and specify their order of appearance: this means that the user must follow a certain "schema" to create an XML file, in order to be able to define and check the meaning of the various elements.

    XML files are widely used in databases, as they allow you to store a large amount of data, which can be extracted with a few instructions. The syntax is rigorous, but at the same time it is a “flexible” metalanguage, since it allows to be read and understood instantly by a human user without having to go through specific software, and can be used in countless ways.

    The basic syntax is to insert a start tag indicating the version of XML in use and the encoding used to interpret the data ( ), while subsequently all the tags that make up the instructions must be inserted. XML data is represented through a start marker, an content it's a end marker. The names of the tags / markers can also be “invented” according to the user's needs.

    To give a concrete example, let's imagine having to "save" the last two articles published on The start marker will then be , while that of the end will be (The symbol / closes a tag / marker, in the same way it does in HTML). The content will obviously be the link to the articles and each of them will have a start marker in turn (in this case ), content (in this case, the name expressed as a parameter and the link to the article expressed as a separate tag) and end ( ). Our final code it will then be the following (as you can see, the tags are spaced from each other through the button Tab keyboard).

    In short, as you may have already understood, it is an intuitive and relatively simple metalanguage to use in less demanding cases.

    Programs for creating XML files

    Given the "power" and "flexibility" of XML files, many programs, such as the Microsoft Office suite, allow you to export data to files with this extension. Below you will find all the details of the case. If you have not yet installed the Office suite programs, you can do so by consulting my guide on how to download Office for free (all the Microsoft suite programs mentioned are included in the Office 365 package).

Xml from the appropriate list and press the button Save, present on the right.

    I remind you, however, that Word could add more information to the file: for this reason, if you care about the purity of the code, I suggest you use other tools dedicated to programming, such as the tool I described in the chapter on how to create files. XML online.

    How to create XML files with programming languages

    How do you say? Are you studying i programming languages and would you like a hand to create an XML file using a specific language of your interest? Don't worry: I'll tell you how to do it right away.

    Create an XML file in VB6

    If you use the programming language Visual Basic 6 and you want to create an XML file and create it on disk, all you have to do is take advantage of these indications.

    The first thing to do is to create all objects related to your XML file (eg. Articles, article e Link, citing the example given above). The function to do this is called createElement ("Name"). After that, you have to create the various attributes and set their node value via the function createAttribute ("Name") and the element nodeValue.

    Finally, after setting everything up correctly, you can save the XML file to disk, via the save function ("output-addressfilename.xml").
