Examples

Using importStylesheet()

This example shows how importStylesheet() loads an XSLT stylesheet into an XSLTProcessor for use in transforming XML data.

HTML

html

<div id="result"></div>

JavaScript

const xmlString = `
<items>
  <item>Item 1</item>
  <item>Item 2</item>
</items>
`;

const xsltString = `
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/">
    <ul>
      <xsl:for-each select="items/item">
        <li><xsl:value-of select="."/></li>
      </xsl:for-each>
    </ul>
  </xsl:template>
</xsl:stylesheet>
`;

const parser = new DOMParser();
const xmlDoc = parser.parseFromString(xmlString, "application/xml");
const xsltDoc = parser.parseFromString(xsltString, "application/xml");

const xsltProcessor = new XSLTProcessor();

// Import the XSLT stylesheet into the XSLTProcessor
xsltProcessor.importStylesheet(xsltDoc);

// Perform the transformation from XML to HTML
const resultFragment = xsltProcessor.transformToFragment(xmlDoc, document);

// Display the transformed result in the page
document.getElementById("result").appendChild(resultFragment);
