XML works by saving and sending information. It acts as a container for data processed by second programming language like PHP or HTML. XML enables document's author to divide formation from design and to make web page that is organized and dynamic. The official formation of XML document takes some practice to understand. One problem that beginner face often is process for line feeds or line space.

· Define root element for XML tree structure. Tree structure works to organize data presented on a page. The first line is root element. For example, a tool catalog may list types of screwdrivers. As screwdrivers are always tools, the root element may begin as tool.
· Next line will be Kids part. Kids part is offshoot of root. Using tool, child element may be screwdriver.
· Enter attributes to specify each kids part. In XML, an attribute mentions Kids element. An attribute for screwdriver may say: "A long tool with a plastic handle. A screwdriver turns a screw."
· Entry "\n" to add line spaces. To decide every line breaks, add line return character, or line space. Correct format for line space is \n.
