java doc文件转xml并生成文件兼容特殊符号代码示例

以下是一个示例代码，可以将JavaDoc转换为XML，并且可以处理特殊字符：

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;

public class JavaDocToXmlConverter {
    public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {
        // read the input file
        File inputFile = new File("input.html");
        BufferedReader reader = new BufferedReader(new FileReader(inputFile));
        StringBuilder sb = new StringBuilder();
        String line;
        while ((line = reader.readLine()) != null) {
            sb.append(line);
        }
        reader.close();

        // replace special characters
        String input = sb.toString();
        input = input.replaceAll("&", "&");
        input = input.replaceAll("<", "&lt;");
        input = input.replaceAll(">", "&gt;");
        input = input.replaceAll("'", "&apos;");
        input = input.replaceAll("\"", "&quot;");

        // convert to xml
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document doc = builder.newDocument();
        Element root = doc.createElement("javadoc");
        doc.appendChild(root);

        Element body = doc.createElement("body");
        root.appendChild(body);

        body.appendChild(doc.createCDATASection(input));

        // write output file
        FileWriter writer = new FileWriter("output.xml");
        writer.write(docToString(doc));
        writer.close();
    }

    private static String docToString(Document doc) {
        String result = "";
        try {
            TransformerFactory tf = TransformerFactory.newInstance();
            Transformer transformer = tf.newTransformer();
            transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
            StringWriter writer = new StringWriter();
            transformer.transform(new DOMSource(doc), new StreamResult(writer));
            result = writer.getBuffer().toString();
        } catch (TransformerException ex) {
            ex.printStackTrace();
        }
        return result;
    }
}

该代码使用Java自带的XML DOM库，将JavaDoc文档解析为XML，并将特殊字符转换为XML实体。输出的XML文件中包含CDATA部分，其中包含原始的JavaDoc文本。最后，将XML文档转换为字符串，并将其写入输出文件。
