How to convert XML to HTML using XSLT in Java

Question

I want to convert XML file into HTML file with help of XSLT. But I am getting an error i.e.

javax.xml.transform.TransformerException: javax.xml.transform.TransformerException: com.sun.org.apache.xml.internal.utils.WrappedRuntimeException: Invalid byte 1 of 1-byte UTF-8 sequence.

XML file

<?xml version="1.0"?>
<Company>
    <Info>
            <EmpId>1</EmpId>
            <EmpName>John</EmpName>
            <Age>25</Age>
          <Salary>20000</Salary>
   </Info>
    <Info>
            <EmpId>2</EmpId>
            <EmpName>Tony</EmpName>
            <Age>27</Age>
            <Salary>23000</Salary>
    </Info>
    <Info>
            <EmpId>3</EmpId>
            <EmpName>Eithen</EmpName>
            <Age>29</Age>
            <Salary>25000</Salary>
    </Info>
</Company>

XSL file

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
   <xsl:template match="/">
      <html>
         <body>
            <h1>Company Details</h1>
            <table border="1">
               <tr>
                  <th>EmpId</th>
                  <th>EmpName</th>
                  <th>Age</th>
                  <th>Salary</th>
               </tr>
               <xsl:for-each select="Company/Info">
                  <tr>
                     <td>
                        <xsl:value-of select="EmpId" />
                     </td>
                     <td>
                        <xsl:value-of select="EmpName" />
                     </td>
                     <td>
                        <xsl:value-of select="Age" />
                     </td>
                     <td>
                        <xsl:value-of select="Salary" />
                     </td>
                  </tr>
               </xsl:for-each>
            </table>
         </body>
      </html>
   </xsl:template>
</xsl:stylesheet>

Java Code

public class TransInfoHtml 
{
public static void main(String args[])
{
try {
        TransformerFactory tFactory=TransformerFactory.newInstance();

        Source xslDoc=new StreamSource("files/NewStylesheet.xsl");
        Source xmlDoc=new StreamSource("D:/Demo.xml");

        String outputFileName="CompanyInfo.html";

        OutputStream htmlFile=new FileOutputStream(outputFileName);
        Transformer trasform=tFactory.newTransformer(xslDoc);
        trasform.transform(xmlDoc, new StreamResult(htmlFile));
    } 
    catch (FileNotFoundException e) 
    {
        e.printStackTrace();
    }
    catch (TransformerConfigurationException e) 
    {
        e.printStackTrace();
    }
    catch (TransformerFactoryConfigurationError e) 
    {
        e.printStackTrace();
    }
    catch (TransformerException e) 
    {
        e.printStackTrace();
    }
}
}

To me, this looks like an encoding problem. Try to ensure that the files are encoded correctly in all cases.

For example, add encoding="UTF-8" to your XML and XSLT file. But note that this is only a declaration - it does not change the characters themselves.

Also, you could copy your XML content into a simple editor and save it explicitly as UTF-8. For instance, if you are using windows, copy the content into notepad, hit "Save as...". In the file dialog, you can choose "UTF-8" from a drop-down.

Your code works fine. In the question stylesheet node was not closed.

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
   <xsl:template match="/">
    ---
   </xsl:template>
</xsl:stylesheet>

Also check the xsl path properly or test by

Source xslDoc=new StreamSource("D:/NewStylesheet.xsl");`

UTF-8 error is resolved. Now it's showing ERROR: 'com.sun.org.apache.xml.internal.utils.WrappedRuntimeException: The entity name must immediately follow the '&' in the entity reference. I checked XML file. It doesn't contain special characters and hierarchy of all tags is proper.plese help

For the special case of convert XHTML pages to HTML, we can use the HTMLWriter from the dom4j API.

@Test
public void givenXHTML_whenWrite_thenGetHTML() throws Exception {
    String xml = "<?xml version='1.0' encoding='UTF-8' ?>" +
      "<html> <body><![CDATA[First&nbsp;test]]> " +
      "<img alt=\"W3C\" height=\"48\" width=\"72\" src=\"http://www.w3.org/Icons/w3c_home\" />" +
      "</body> </html>";
    Document document = DocumentHelper.parseText(xml);
    StringWriter buffer = new StringWriter();
    HTMLWriter writer = new HTMLWriter(buffer);
    String expects = "\n<html>\n" +
      "  <body>First&nbsp;test\n    "
      + "<img alt=\"W3C\" height=\"48\" width=\"72\" src=\"http://www.w3.org/Icons/w3c_home\">\n  "
      + "</body>\n" + "</html>\n";

    writer.write(document);
    String output = buffer.toString();

    assertThat(output).isEqualTo(expects);
}
