XML learning: How to apply the XML language

First, you must understand that XML is designed to store data, carry data, and exchange data. it is not designed to display data. XML can use XML to store data separately from HTML files. When XML is not applied, H must first understand that XML is designed to store data, carry data, and exchange data. it is not designed to display data.

　　XML can separate data from HTML

XML allows you to store data outside HTML files. When XML is not applied, HTML is used to display data. data must be stored in HTML files. When XML is applied, the data can be stored in different XML documents. This method allows you to focus on the display and layout of data in the application HTML, and ensure that data correction does not cause HTML files to be corrected as well. In this way, the page can be easily protected. XML data can also be stored in the HTML page in the form of "data Island. You can still focus on applying HTML pattern and displaying data.

　　XML for data exchange

With XML, we can exchange data between incompatible systems. In real life, the number of data stored in the computer system and database system occupies N ^ N forms. for developers, the most time-consuming is to exchange data between systems on the network. Converting data to XML format storage will greatly reduce the complexity of data exchange and allow different programs to read the data.

　　XML and B2B

XML can be used to exchange financial information on the network. In the near future, we can see a lot about XMl and B2B (Business To Business. XML is becoming an important language used to exchange financial information between trading systems across networks. Many complete XML-based exploitation programs related to B2B are under development.

　　XML can be used to share data

Using XML, plain text files can be used to share data. Since XML data is stored in plain text format, XML provides a data sharing method unrelated to software and hardware. In this way, it becomes simple to create a data file that can be read by different exploitation programs. Similarly, it is much easier for us to control the system at the provincial level, upgrade servers, upgrade exploitation programs, and update browsers.

　　XML can be used to store data.

XML can be used to store data in plain text files. A large amount of data can be stored in XML files or databases. A program can read, write, and store data. a general program can display data.

　　XML can make full use of data

Application XML, your data can be applied by more users. Since XML is irrelevant to software, hardware, and utilization programs, it can make your data available to more users and devices, not just HTML-based browsers. Other clients and applications can process your XML documents as data sources. just as they look at the database, your data can be processed by various "browsers, it is convenient for some people, such as the blind or the disabled.

　　XML can be used to create a new language

XML is the mother of WAP and WML languages. The Wireless Markup Language (WML) identifies an Internet program running on a handheld device (such as a mobile phone.

　　Future

If the developer has a hunch, all future exploitation programs should use XML to store data. In the future, the word processors, spreadsheet software, and databases we will use should be able to read data from each other in a plain text format, without the need for a transformation process. We can only expect Microsoft and other software developers to agree with this. // In fact, Microsoft is vigorously developing XML utilization.
