XSLTProcessor: setParameter() method
Deprecated
Avoid using this feature in new projects. XSLT is a candidate for removal from browsers because browser implementations are highly susceptible to memory safety vulnerabilities. This feature may be a candidate for removal from web standards or browsers.
The setParameter() method of the XSLTProcessor interface sets the value of a parameter (<xsl:param>) in the stylesheet imported in the processor.
Syntax
setParameter(namespaceURI, localName, value)
Parameters
namespaceURI-
The namespace associated with the parameter name. A "null" value is treated the same as the empty string (
""). localName-
The name of the parameter in the associated namespace.
value-
The value of the parameter.
Note: Firefox supports any kind of parameter. Chrome, Edge and Safari only support string parameters.
Return value
None (undefined).
Examples
Using setParameter()
This example demonstrates how to pass parameters from JavaScript to an XSLT stylesheet using setParameter(), allowing for dynamic modification of the transformation output based on these parameters.
HTML
<div id="result"></div>
JavaScript
const xmlString = `
<items>
<item>Item 1</item>
<item>Item 2</item>
<item>Item 3</item>
</items>
`;
const xsltString = `
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="showItems" select="'yes'"/>
<xsl:param name="highlightColor" select="'yellow'"/>
<xsl:template match="/">
<ul>
<xsl:if test="$showItems = 'yes'">
<xsl:for-each select="items/item">
<li style="background-color: {$highlightColor};">
<xsl:value-of select="."/>
</li>
</xsl:for-each>
</xsl:if>
</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();
xsltProcessor.importStylesheet(xsltDoc);
xsltProcessor.setParameter(null, "showItems", "yes");
xsltProcessor.setParameter(null, "highlightColor", "lightblue");
// 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);
