Package Exports

xsltjs

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (xsltjs) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

XSLTjs

An XSLT 1.0+ implementation written entirely in JavaScript.

Introduction

This is a partial implementation of XSLT 1.0 and XSLT 2.0. Among its features:

Pure 100% JavaScript implementation requiring no C++, C#, or Java binding
Support for XML namespaces
Support for include/import
Support for XSL-T functions
Drop-in compatibility with xslt4node

XSLT elements supported

<xsl:apply-templates>
<xsl:attribute>
<xsl:call-template>
<xsl:choose>
<xsl:comment>
<xsl:copy>
<xsl:copy-of>
<xsl:decimal-format>
<xsl:element>
<xsl:for-each>
<xsl:function>
<xsl:if>
<xsl:import>
<xsl:include>
<xsl:otherwise>
<xsl:output>
<xsl:param>
<xsl:processing-instruction>
<xsl:sort>
<xsl:stylesheet>
<xsl:transform>
<xsl:template>
<xsl:text>
<xsl:value-of>
<xsl:variable>
<xsl:when>
<xsl:with-param>

XSLT XPath functions supported (beyond those from the XPath module)

function-available()
current()
document()
format-number()
replace()
lower-case()
upper-case()
matches()
generateId()

Acknowledgements

XSLTjs is based on AJAXSLT, originally developed by Steffen Meschkat at Google. That version was developed around 2005 as a stopgap solution for "fat web pages" at a time when XSLT processors weren't found in all web browsers.

This version is a substantial reworking of that original work for use in Node.js (other uses will need accommodation). Below is a partial list of enhancements:

Substantial rewrite to ES2015 standards
Fomatting of JavaScript to SemiStandard.
Replacement of internal implementations of XML DOM and XPath with XmlDOM and XPath modules available from NPM.
Support for namespaces
Support for extended (but still partial) set of XSLT functions used with XPath expressions.
Support for extended set of XSLT elements.
Drop-in compatibility with xslt4node.

At this point, features are being added as needed on our projects. Contributions are always welcome.

Installation

npm install XSLTjs --save

Usage example

  const transformSpec = {
    source: inputXML|inputDoc,
    xsltPath: transformPath, // Optional
    xslt: transformXML|transformDoc, // Optional
    result: string|function,
    params: {
      'docName': 'My Document',
      'docDate': 'February 24, 2019'
    }
  };
  XSLT.transform(transformSpec, (errorMessage, resultXML) => {
    if (errorMessage) {
      throw new Error(error);
    } else if (resultXML) {
      ...
    }
  });
