word to html java

With the development of the Internet, HTML has become the basic language for web development. In daily work, if you need to convert a Word document into HTML format, you can use the Java programming language to achieve this. In this article, we will explain how to convert a Word document to HTML using Java.

1. Understand the structure of Word document

Before converting Word document to HTML, we need to understand the structure of Word document. A Word document is not essentially a plain text file, but a structured file composed of XML tags. XML is a markup language that defines relationships between individual document elements. A Word document is a complex XML file that contains text content, format, style and other information.

Therefore, the main task of converting a Word document to HTML is to parse the XML structure of the Word document and convert it into HTML tags.

2. Use Java native methods to convert Word documents

In Java, we can use native methods to convert Word documents to HTML. Java provides a set of classes in the javax.xml.transform and javax.xml.transform.stream packages that can implement XML to HTML conversion.

First, we need to get the input stream of the Word document. This can be achieved using the FileInputStrem class in Java:

FileInputStream fileInputStream = new FileInputStream("Word文档路径");

Next, we can use the POIXMLDocument class to convert the input stream into a XWPFdocument object, To obtain the XML content of the Word document:

XWPFdocument xwpfdocument = new XWPFDocument(fileInputStream);
String rawXml = xwpfdocument.getDocument().getBody().getXHTML();

Finally, we can use the Transformer class to convert the XML content into an HTML file:

FileOutputStream fileOutputStream = new FileOutputStream("HTML文件路径");
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
StreamSource streamSource = new StreamSource(new StringReader(rawXml));
StreamResult streamResult = new StreamResult(fileOutputStream);
transformer.transform(streamSource, streamResult);

In the above code, we use # The ##TransformerFactory class creates a Transformer object that is used to convert XML content into an HTML file. The StreamSource class represents the input XML data stream, and the StreamResult class represents the output stream.

3. Use third-party libraries to convert Word to HTML

In actual development, we can also use third-party libraries to convert Word documents to HTML. These libraries usually provide more convenient APIs that can simplify our code. The following is a sample code that uses the

poi-ooxml and jodconverter libraries to convert Word to HTML:

File inputFile = new File("Word文档路径");
File outputFile = new File("HTML文件路径");

// 创建连接管理器
LocalOfficeManager manager = LocalOfficeManager.builder().officeHome("OpenOffice安装目录").install().build();
manager.start();

// 将 Word 文档转换为 HTML 文件
DocumentConverter converter = LocalConverter.builder().officeManager(manager).build();
converter.convert(inputFile).to(outputFile).execute();

// 关闭连接管理器
manager.stop();

In the above code, we use the

LocalOfficeManager class Created a connection manager for connecting to local OpenOffice. DocumentConverter is used to perform file conversion. We only need to call the convert function and specify the input and output files to convert the Word document into an HTML file.

When using third-party libraries, we need to pay attention to the version of the library and the corresponding OpenOffice version. This is because the underlying third-party library depends on OpenOffice and needs to be configured accordingly according to the version of OpenOffice.

4. Summary

This article introduces how to use the Java programming language to convert Word documents into HTML format. We can use Java's native methods or use the functions of third-party libraries to achieve this conversion. Regardless of the approach, we need to understand the structure of the Word document in order to be able to parse the XML structure of the Word document through Java programming.
