XQuery HTML Format
In XQuery, you can use the XML output method to create or transform XML data, including HTML documents, in a structured way. XQuery allows you to generate HTML content by constructing XML elements and attributes within the query. Once you’ve created the XML representation of the HTML content, you can output it as HTML using the appropriate serialization options.
Here’s a basic example of using XQuery to generate an HTML document:
let $title := "Welcome to My Website"
let $content := "This is the content of my page."
return
<html>
<head>
<title>{$title}</title>
</head>
<body>
<p>{$content}</p>
</body>
</html>This XQuery generates the following HTML output:
<html>
<head>
<title>Welcome to My Website</title>
</head>
<body>
<p>This is the content of my page.</p>
</body>
</html>In this example, we construct an HTML document using XML element literals and XQuery variables ($title and $content). The curly braces {} are used for embedding XQuery expressions within the XML content.
To output the HTML document as formatted HTML, you need to set the serialization method to “html” in XQuery. This can be done using the declare statement at the beginning of your XQuery:
declare option output:method "html";With this declaration, the output will be properly formatted as an HTML document when you execute the XQuery.
Keep in mind that XQuery is not primarily designed for generating HTML content, and its HTML generation capabilities are limited compared to dedicated templating languages like XSLT or JavaScript frameworks like React or Vue.js. However, for simple HTML generation or transforming XML to HTML, XQuery can be a convenient option, especially when you’re already working with XML data. For more complex HTML generation tasks, it’s recommended to use a dedicated HTML templating tool.
