How to Use xsltproc on macOS: A Comprehensive Guide

xsltproc is a command-line tool used for applying XSLT (Extensible Stylesheet Language Transformations) to XML documents. It is a powerful utility for developers and system administrators who need to transform XML data into various formats such as HTML, text, or other XML documents. While xsltproc is not exclusive to any specific operating system, it is widely used in Unix-like environments, including macOS.

In the context of macOS, xsltproc can be easily installed and used thanks to the underlying Unix-based architecture of the operating system. This article will guide you through the installation process, basic usage, and provide practical examples to help you get started with xsltproc on your macOS system.

Examples:

  1. Installing xsltproc on macOS:

    xsltproc is part of the libxslt library, which can be installed via Homebrew, a popular package manager for macOS. If you don't have Homebrew installed, you can install it by running the following command in your Terminal:

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

    Once Homebrew is installed, you can install xsltproc by running:

    brew install libxslt

  2. Basic Usage of xsltproc:

    To use xsltproc, you need an XML file and an XSLT stylesheet. Below are sample files for demonstration:

    • sample.xml:

      <?xml version="1.0" encoding="UTF-8"?>
<catalog>
 <book id="bk101">
     <author>Gambardella, Matthew</author>
     <title>XML Developer's Guide</title>
     <genre>Computer</genre>
     <price>44.95</price>
     <publish_date>2000-10-01</publish_date>
     <description>An in-depth look at creating applications with XML.</description>
 </book>
</catalog>

    • sample.xsl:

      <?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:template match="/">
     <html>
     <body>
         <h2>Book Catalog</h2>
         <table border="1">
             <tr bgcolor="#9acd32">
                 <th>Title</th>
                 <th>Author</th>
                 <th>Price</th>
             </tr>
             <xsl:for-each select="catalog/book">
             <tr>
                 <td><xsl:value-of select="title"/></td>
                 <td><xsl:value-of select="author"/></td>
                 <td><xsl:value-of select="price"/></td>
             </tr>
             </xsl:for-each>
         </table>
     </body>
     </html>
 </xsl:template>
</xsl:stylesheet>

    To transform the XML file using the XSLT stylesheet, run the following command in your Terminal:

    xsltproc sample.xsl sample.xml -o output.html

    This command will generate an HTML file named output.html containing the transformed data.

  3. Advanced Usage:

    xsltproc offers various options for advanced usage. For instance, you can pass parameters to the XSLT stylesheet using the --stringparam option:

    xsltproc --stringparam paramName paramValue sample.xsl sample.xml -o output.html

    You can also use the --output option to specify the output file:

    xsltproc --output output.html sample.xsl sample.xml
