<s1 title="Command-Line Utility">
   
   <s2 title="Using the Command-Line Utility">
      <p>To perform a transformation, you can call &xslt4j; from the command line (or script), 
      an applet, an application, or a servlet (see <link idref="usagepatterns">Usage Patterns</link>).</p>
     <p>The org.apache.xalan.xslt.Process main() method provides a command-line interface
    for performing XSL transformation. To perform a transformation from the command line or a script,
    do the following:</p>
 		<ol>
    <li>Download &xslt4j;.<br/><br/></li> 
    <li><link idref="getstarted" anchor="classpath">Set the Java classpath</link> to include xalan.jar, xml-apis.jar, and
    &xml4j-jar; -- or another conformant XML Parser -- see <link idref="usagepatterns" anchor="plug">Plugging in 
    the Transformer and XML parser</link>).<br/><br/></li>
    <li>Call java and the Process class with the appropriate flags and
    arguments (described below). The following command line, for example, includes the -IN, -XSL,
    and -OUT flags with their accompanying arguments -- the XML source document, the XSL
    stylesheet, and the output file:<br/><br/>
    <code>java org.apache.xalan.xslt.Process -IN foo.xml -XSL foo.xsl -OUT foo.out</code>
    </li></ol>
    <p>The command line utility can take the following flags and arguments (the flags are case insensitive):</p> 
      <source>-IN inputXMLURL
-XSL XSLTransformationURL
-OUT outputFileName
-V (Version info)
-QC (Quiet Pattern Conflicts Warnings)

-L (Use line numbers for source document)
-TT (Trace the templates as they are being called)
-TG (Trace each result tree generation event)
-TS (Trace each selection event)
-TTC (Trace the template children as they are being processed)
-EDUMP [optional]FileName (Do stackdump on error)
-XML (Use XML formatter and add XML header)
-TEXT (Use simple Text formatter)
-HTML (Use HTML formatter)
-PARAM name value (Set a stylesheet parameter)
-DIAG (Print number of milliseconds transform operation took)
-FLAVOR flavorName (Transform with SAX for s2s or DOM for d2d)
-URIRESOLVER fullClassName (Use a custom URIResolver)
-ENTITYRESOLVER fullClassName (Use a custom EntityResolver)
-CONTENTHANDLER fullClassName (Use a custom ContentHandler)
-INCREMENTAL (Request incremental transform by setting
  http://xml.apache.org/xalan/features/incremental to true)
-NOOPTIMIZE (Request no optizimation of stylesheet processing
  by setting http://xml.apache.org/xalan/features/optimize to
  false)
-RL recursionLimit (Set numeric limit on depht of stylesheet 
  recursion)
-L (Obtain a SourceLocator that can be used within stylesheet to 
  report location of nodes within the XML source document)      
</source>
      <p>Use <code>-IN</code> to specify the XML source document.</p> 
      <p>Use <code>-XSL</code> to specify the XSL stylesheet file.</p>
      <p>Use <code>-TEXT</code> if you want the output to include only element values (not element tags with element names and
      attributes).</p>
      <p>Use <code>-HTML</code> to write 4.0 transitional HTML (some elements, such as &lt;br&gt;, are
      not well formed XML).</p>
      <p>To set stylesheet parameters from the command line, use <br/>
      <code>java org.apache.xalan.xslt.Process -PARAM <ref>name value</ref></code></p>
      <p>The value is passed to the transformer as a String.</p>
      <p>For information about incremental and optimized stylesheet processing, see <link idref="dtm" anchor="settings">DTM settings</link>.</p>
      <p>Use <code>-URIRESOLVER</code> with a fully qualified class name to utilize a custom implementation of the
      <jump href="apidocs/javax/xml/transform/URIResolver.html">URIResolver</jump> TrAX interface to resolve URIs for
       xsl:include, xsl:import, and the document() function.</p>
       <p>Use <code>-ENTITYRESOLVER</code> with a fully qualified class name to utilize a custom implementation of the
       <jump href="apidocs/org/xml/sax/EntityResolver.html">EntityResolver</jump> SAX interface to handle external entity references.</p>
       <p>Use <code>-CONTENTHANDLER</code> with a fully qualified class name to utilize a custom implementation of the 
       <jump href="apidocs/org/xml/sax/ContentHandler.html">ContentHandler</jump> SAX interface to serialize output.</p>
       <note>If you want to validate an XML document (verify that it adheres to its DOCTYPE declatation), you can use the <link idref="samples" anchor="validateutility">Validate utility</link> shipped with &xslt4j-current;.</note>
