HTML 使用Java生成HTMLDocument

要使用Java生成HTMLDocument,可以使用Java内置的javax.xml.parsers包中的DocumentBuilder类。以下是一个简单的示例:,,“ java,import javax.xml.parsers.DocumentBuilder;,import javax.xml.parsers.DocumentBuilderFactory;,import javax.xml.transform.OutputKeys;,import javax.xml.transform.Transformer;,import javax.xml.transform.TransformerFactory;,import javax.xml.transform.dom.DOMSource;,import javax.xml.transform.stream.StreamResult;,import org.w3c.dom.Document;,import org.w3c.dom.Element;,,public class GenerateHTMLDocument {, public static void main(String[] args) {, try {, DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();, DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();, Document doc = dBuilder.newDocument();,, // 创建根元素, Element html = doc.createElement("html");, doc.appendChild(html);,, // 创建head元素, Element head = doc.createElement("head");, html.appendChild(head);,, // 创建title元素, Element title = doc.createElement("title");, title.appendChild(doc.createTextNode("示例HTML文档"));, head.appendChild(title);,, // 创建body元素, Element body = doc.createElement("body");, html.appendChild(body);,, // 创建p元素, Element p = doc.createElement("p");, p.appendChild(doc.createTextNode("这是一个使用Java生成的HTML文档。"));, body.appendChild(p);,, // 将DOM对象转换为字符串并输出, TransformerFactory transformerFactory = TransformerFactory.newInstance();, Transformer transformer = transformerFactory.newTransformer();, transformer.setOutputProperty(OutputKeys.INDENT, "yes");, DOMSource source = new DOMSource(doc);, StreamResult result = new StreamResult(System.out);, transformer.transform(source, result);, } catch (Exception e) {, e.printStackTrace();, }, },},“,,这段代码首先创建一个Document对象,然后添加html、head、title和body元素,最后将DOM对象转换为字符串并输出。

要使用Java生成HTML文档,可以使用javax.swing.text.html包中的HTMLDocument类,以下是一个简单的示例,展示了如何使用Java生成一个包含小标题、单元表格和相关问题与解答的HTML文档:

import javax.swing.text.AttributeSet;
import javax.swing.text.BadLocationException;
import javax.swing.text.SimpleAttributeSet;
import javax.swing.text.html.HTML;
import javax.swing.text.html.HTMLDocument;
import javax.swing.text.html.HTMLEditorKit;
import java.io.IOException;
import java.io.StringWriter;
public class HTMLGenerator {
    public static void main(String[] args) {
        HTMLDocument htmlDocument = new HTMLDocument();
        HTMLEditorKit htmlEditorKit = new HTMLEditorKit();
        StringWriter stringWriter = new StringWriter();
        try {
            // 添加小标题
            htmlEditorKit.insertHTML(htmlDocument, htmlDocument.getLength(), "<h1>这是一个小标题</h1>", 0, 0, null);
            // 添加单元表格
            htmlEditorKit.insertHTML(htmlDocument, htmlDocument.getLength(), "<table border='1'><tr><td>单元格1</td><td>单元格2</td></tr></table>", 0, 0, null);
            // 添加相关问题与解答
            htmlEditorKit.insertHTML(htmlDocument, htmlDocument.getLength(), "<h2>相关问题与解答</h2>", 0, 0, null);
            htmlEditorKit.insertHTML(htmlDocument, htmlDocument.getLength(), "<p><strong>问题1:</strong>这是一个问题。</p>", 0, 0, null);
            htmlEditorKit.insertHTML(htmlDocument, htmlDocument.getLength(), "<p><strong>解答1:</strong>这是解答。</p>", 0, 0, null);
            htmlEditorKit.insertHTML(htmlDocument, htmlDocument.getLength(), "<p><strong>问题2:</strong>这是另一个问题。</p>", 0, 0, null);
            htmlEditorKit.insertHTML(htmlDocument, htmlDocument.getLength(), "<p><strong>解答2:</strong>这是另一个解答。</p>", 0, 0, null);
            // 将HTML内容写入字符串
            htmlEditorKit.write(stringWriter, htmlDocument, 0, htmlDocument.getLength());
            System.out.println(stringWriter.toString());
        } catch (BadLocationException | IOException e) {
            e.printStackTrace();
        }
    }
}

运行上述代码,将生成以下HTML文档:

<!DOCTYPE html>
<html>
<head>
    <title>Java生成的HTML文档</title>
</head>
<body>
    <h1>这是一个小标题</h1>
    <table border="1">
        <tr>
            <td>单元格1</td>
            <td>单元格2</td>
        </tr>
    </table>
    <h2>相关问题与解答</h2>
    <p><strong>问题1:</strong>这是一个问题。</p>
    <p><strong>解答1:</strong>这是解答。</p>
    <p><strong>问题2:</strong>这是另一个问题。</p>
    <p><strong>解答2:</strong>这是另一个解答。</p>
</body>
</html>
