Converting HTML to XHTML

您可以将现有的 HTML 网站转换为 XHTML 网站。

You can convert your existing HTML website into XHTML website.

让我们回顾一些重要的步骤。要转换现有的文档，您必须首先决定要遵守哪个 DTD，并在文档顶部包括文档类型定义。

Let us go through some important steps. To convert your existing document, you must first decide which DTD you are going to adhere to, and include document type definition at the top of the document.

  1. Make sure you have all other required elements. These include a root element <html> that indicates an XML namespace, a <head> element, a <title> element contained within the <head> element, and a <body> element.

  2. Convert all element keywords and attribute names to lowercase.

  3. Ensure that all attributes are in a name="value" format.

  4. Make sure that all container elements have closing tags.

  5. Place a forward slash inside all standalone elements. For example, rewrite all <br> elements as <br />.

  6. Designate client-side script code and style sheet code as CDATA sections.
