Sample text

The server-side file will query the database, receive the records, and generate the XML structure. It will either return a stream of XML-formatted information or save a physical XML document. To use this approach, you’ll need to have a web server capable of processing the server-side language. This might be Internet Information Server (IIS), Apache, or ColdFusion. You’ll also need to use a database like Access, MySQL, SQL Server, or Oracle to store the information. NET, PHP, and ColdFusion. We’ll generate an XML stream similar in structure to the resource file ]``naoo* tih from a database.

My intention is to provide a walk-through, rather than a complete tutorial. The aim here is not to make you an expert in each server-side language, but rather to give you a brief introduction to show you how to generate XML in this manner. If you need to carry out this task on a regular basis, you might want to further develop your skills in this area. You can use any database to provide the content. To make the example simpler, I’ll use an Access database for all three examples. It contains a single table called ldkja>kkg, made up of E@, _kjp]_pj]ia, ]``naoo, and ldkja fields.

You can use the unqualified versions of these attribute names. So, h]jc, ol]_a, hejg, and ]ppne^qpa would be fine. Structuring attributes as elements You can rewrite attributes as nested elements, as follows: 8_kjp]_pe`9-: 8j]ia:O]oF]_k^o8+j]ia: 8+_kjp]_p: The preceding XML fragment could also be written in this way: 8_kjp]_p: 8e`:-8+e`: 8j]ia:O]oF]_k^o8+j]ia: 8+_kjp]_p: There is no one right way to structure elements and attributes. The method you choose depends on your data. The way you’re going to process the XML document might also influence your choices.
