XSLTProcessor: transformToDocument() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The transformToDocument() method of the XSLTProcessor interface transforms the provided Node source to a Document using the XSLT stylesheet associated with XSLTProcessor.

Syntax

js
transformToDocument(source)

Parameters

source

The Node source to apply the XSLT stylesheet to.

Return value

A Document. The actual interface depends on the output method of the stylesheet:

Output method Result interface
html HTMLDocument
xml XMLDocument
text XMLDocument with a single root element <transformiix:result> with the text as a child

Examples

Using transformToDocument()

This example demonstrates how to use transformToDocument() to transform an XML document using XSLT, resulting in a new XML document structure.

HTML

html
<pre id="result"></pre>

JavaScript

js
const xmlString = `
<books>
  <book>
    <title>Book 1</title>
    <author>Author 1</author>
  </book>
  <book>
    <title>Book 2</title>
    <author>Author 2</author>
  </book>
</books>
`;

const xsltString = `
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes"/>
  <xsl:template match="/">
    <catalog>
      <xsl:for-each select="books/book">
        <item>
          <name><xsl:value-of select="title"/></name>
          <writer><xsl:value-of select="author"/></writer>
        </item>
      </xsl:for-each>
    </catalog>
  </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();
xsltProcessor.importStylesheet(xsltDoc);

// Perform the transformation, returning the result as a new XML document
const resultDoc = xsltProcessor.transformToDocument(xmlDoc);

// Serialize the result document to a string
const serializer = new XMLSerializer();
const resultString = serializer.serializeToString(resultDoc);

// Display the transformed XML in the page
document.getElementById("result").textContent = resultString;
