How Java Transforms XML Files into HTML or Other Formats Using XSLT Expressions
Transforming XML files into HTML or other formats using XSLT expressions in Java can be achieved through the following steps:
1. Import Dependency: Add the following Maven dependencies to the pom.xml file (you can also manually download the jar file to import the project):
<dependency>
<groupId>javax.xml</groupId>
<artifactId>jaxp-api</artifactId>
<version>1.4.5</version>
</dependency>
2. Create an XSLT converter: Create a TransformerFactory object using the TransformerFactory class in the javax. xml. transform package, and then use this object to create a Transformer object. TransformerFactory is Thread safety, so it can be reused throughout the application.
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();
3. Define an XSLT stylesheet: Create an XSLT stylesheet file that contains conversion rules for converting XML into HTML or other formats. The following is a simple example of an XSLT-style representation that converts the name element in XML into an HTML h1 title:
<!-- test.xslt -->
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<head>
<title>XML to HTML Conversion</title>
</head>
<body>
<h1>
<xsl:value-of select="name"/>
</h1>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
4. Perform conversion: Use the Transformer object to convert the XML file to an XSLT stylesheet file, and save the results to the target file.
import javax.xml.transform.Source;
import javax.xml.transform.Result;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.stream.StreamResult;
import java.io.File;
File xmlFile = new File("input.xml");
File xsltFile = new File("test.xslt");
File outputFile = new File("output.html");
Source xmlSource = new StreamSource(xmlFile);
Source xsltSource = new StreamSource(xsltFile);
Result outputResult = new StreamResult(outputFile);
transformer.transform(xmlSource, outputResult);
The above code assumes an input XML file called "input. xml", which contains a name element. The converted results will be saved in an HTML file called "output. html".
It should be noted that the above example code is only a simple demonstration. If you need to handle more complex XML and XSLT transformations, please refer to relevant documents and tutorials.
