At the moment, however, we are dealing only with Database Engines, which one to load and build, and the first child tag is. The root tag is going to have child tags which identify various configuration data. We start with defining the root tag and name it because that's what our XML file is all about. The next thing to do is to define the tags, or the words, describing our configuration data in a way that allows us to extend configuration files in the future, whenever this may be required. An XML parser will fail to process an XML file correctly unless this specification is met. The tag is required due to the XML file specification. The first thing an XML file must contain is the tag identifying the XML version used in a file. This is also the case for our small configuration file project. Xml notepad deutsch software#There are a couple of tools available already to edit XML documents - one is Microsoft's XML Notepad (), another more sophisticated one is XMLSPY ().Īs always, the design stage is the most time consuming part of the software development process. You are always on the safe side with XML.įurthermore, because XML is already a well accepted standard, you can expect more and more tools to become available over time which ease the editing, parsing and data-exchange of information based on XML. As a matter of fact, whenever you need a file format to exchange data or to store configuration data - simply start drafting your own XML document. XML files can be used anytime you have to store information outside a database, or when you have to exchange information between applications. It is flexible enough to manage data of high complexity that can be stored in an ASCII compliant file format. The tag names define the allowed words (grammar) for a data structure.Īs you can see, XML is a pretty simple file format. The opening tag defines the meaning (semantic) of embedded information and the closing tag defines the end of data. has a child tag, has child tags, , and so forth. They contain information that can be represented as a tree, or as a parent/child hierarchy. This example demonstrates how data is organized in XML files. Xml notepad deutsch code#The following XML code illustrates a simple, well-formed XML document used to describe the data structure for a customer address: This is the only tag that has no closing pendant. The second rule requires all XML files to begin with an tag which identifies the file as being an XML file and includes version information. This means that textual content in a file must be embedded in an opening and closing tag. The first rule is that all XML files must be "well-formed". Since XML is a mark-up language, similar to HTML, there are some rules to comply with. As a matter of fact, XML is a meta-language that allows you to define your own language to describe documents, or data structures, and that is what makes XML the file format of choice for managing configuration data. in XML you can define the names for tags and their meaning, the context in which they may appear, and you can define attributes for tags and their meaning. With these "definition of terms", the XML definition above is much better to understand: XML allows you to define your own grammar for mark-up, i.e. For example, is a string defining the HTML tag whose ALIGN attribute has the value "RIGHT". is a tag existing in all HTML documents, for example.Īn attribute is part of a tag and defines additional information for mark-up. However, they are visible in an ASCII or HEX editor.Ī tag is a word enclosed in an opening and closing delimiter. The markers are invisible when the text is displayed or printed. For example, italic or bold markers are included in a text but do not contribute to its contents. This term describes all characters in a text that define how text is displayed or printed. The semantic of the words "Deutsch" and "German" is identical, depending on the language. "Deutsch" is not part of the English language, it is part of the German language. This term describes the meaning of the words allowed in a language. This term describes the words allowed in a language and how or where they may appear in a sentence. There are some terms that need an explanation: However, don't be disappointed if it doesn't tell much to you. XML enables you to define a grammar for marking up documents in terms of semantic tags and their attributes. To answer this questions, we will start with a definition found in one of the numerous books presenting XML introductions: ![]()
