XSL transformations in Python

I want to describe how to do XSL transformations in Python by using 4Suite. It is a really easy, and requires just a few steps:

  1. Install 4Suite technologies for Python:
    $ sudo yum install python-4Suite-XML
    
  2. Create a required XML file (for example, simple1.xml):
    <!-- The stylesheet to apply -->
    <?xml-stylesheet href="simple.xsl" type="text/xsl"?>
    <document cache-methods="get,post">
            <title>Simple XSLT sample</title>
            <body>
                    <heading>Simple XSLT sample</heading>
                    <paragraph>
                            This is a sample text.
                    </paragraph>
            </body>
    </document>
    
  3. Create a required XSL file (for example, simple1.xsl):
    <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
            <!-- 
                    Output an XHTML/transitional document (uses html output method
                    as Xalan does not support xhtml)
             -->
            <xsl:output method="html" indent="yes" version="4.0" encoding="us-ascii"
    media-type="text/html" doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
    doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" />
            <!-- Match the document root -->
            <xsl:template match="/document">
                    <!-- Output an html document -->
                    <html>
                            <!-- Copy the title -->
                            <head><title><xsl:value-of select="title" /></title></head>
                            <!-- Process the body -->
                            <body>
                                    <xsl:apply-templates select="body" />
                            </body>
                    </html>
            </xsl:template>
            
            <!-- Match a heading -->
            <xsl:template match="heading">
                    <h1><xsl:apply-templates select="node()" /></h1>
            </xsl:template>
            
            <!-- Match a paragraph -->
            <xsl:template match="paragraph">
                    <p><xsl:apply-templates select="node()" /></p>
            </xsl:template>
                    
    </xsl:stylesheet>
    
  4. Run Python code:
    $ ipython
    In [1]: from Ft.Xml.Xslt import Transform
    In [2]: result = Transform('simple1.xml', 'simple1.xsl')
    In [3]: print result
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html>
      <head>
        <meta content="text/html; charset=us-ascii" http-equiv="Content-Type">
        <title>Simple XSLT sample</title>
      </head>
      <body>
                    
        <h1>Simple XSLT sample</h1>
                    
        <p>
                            This is a sample text.
                    </p>
            
      </body>
    </html>
    
    

The main magic is Transform function - it takes XML and XSL files and do transformation. For further digging take a look to 4Suite demos.

Happy transformations! :-)
