designed to display data and concentrate on the Data appearance. XML is designed to describe data and concentrate on data content.
3. Similar to HTML, XML does not perform any operations. Although the XML tag can be used to describe the structure of an item such as an order
definition (DTD. If a document complies with a schema, this document is schema valid ).
Relationship between HTML and XML
1. In fact, there is no inevitable link between HTML and XML. XML is not to replace HTML. In fact,
to store more data at the beginning. after all, you will never know which data may be useful.
After storing data in a database or similar data storage, you can create a report. Creating a report may be simple. you only need to run several basic SQL queries on the database to view the number of times a data appears. Alternatively, creating a report may be a very complex Web user interface, it is designed to allow users to gain insight into data and discover relationships between data.

Therefore, IE does not support XHTML I don't know what to do, but IE does not fully support CSS is true, but, but CSS is performance, performance and structure is irrelevant.
I. Introduction to XML Technology
XML (extensible Markup Language?? Extensible Markup Language is an extensible source markup language that can be used to define other languages.
It is a simplified subset of SGML, which is designed specifically for the web environment, which means that it must handle data-oriented (rather than publishing-oriented), short-lived (and actually dynamically generated) informat

Limitations of XML
Currently, the content data for many Web sites are stored in a database or data file. For Web program developers, if you want to extract useful information from a database, the traditional approach is to write scripts on the server side (such as VBScript, JavaScript, CGI, ASP, Perl, and so on) and get records by executing SQL queries against the database. The query results are then or

XML vs. HTML:
Two words: 1,xml is designed to describe the data, the focus is: what is the data, how to store the data. 2,html is designed to display
intrinsic markup.2. HTML tags are predefined; XML tags are free, customizable, and extensible.(iii), different functions:1. HTML is used to display data, XML is used to describe the data, storing data, so it can be used as a persistent medium!

1. CSS is the partner of HTML.
In the coding process, HTML plays a different role: HTML is responsible for the specific content (structure) of the webpage, while CSS modifies the form (layout) of the webpage ).
CSS has a superior feature, that is, it can centrally manage the page layout. That is to say, you do not need to use the style attribute in each label
