 <P>To perform a transformation, use one of the <A href="apiDocs/classXalanTransformer.html">XalanTransformer
    </A> transform() methods. The transformation requires an XML source document and an XSL stylesheet. Both of these objects
    may be represented by instances of <A href="apiDocs/classXSLTInputSource.html">XSLTInputSource </A>. You can construct
    an XSLTInputSource with a string (the system ID for a file or URI), an input stream, or a DOM.</P>
 <P>If you are using an XSL stylesheet to perform a series of transformations, you can improve performance by calling transform()
    with a compiled stylesheet, an instance of <A href="apiDocs/classXalanCompiledStylesheet.html">XalanCompiledStylesheet</A>.
    If you are transforming an XML source more than once, you should call transform() with a parsed XML source, an instance of
    <A href="apiDocs/classXalanParsedSource.html">XalanParsedSource</A>. See <A href="#compiled">Performing a series of
    transformations</A>.</P>
 <P>If you XML source document contains a stylesheet Processing Instruction (PI), you do not need to include a stylesheet object
   when you call transform().</P>
 <P>The transformation output is represented by an <A href="apiDocs/classXSLTResultTarget.html">XSLTResultTarget</A>, which
    you can set up to refer to an output stream, the system ID for a file or URI, or a Formatter for one of the various styles of
    DOM output.</P>

 <P>You can include the -param flag with two arguments when you call the <A href="commandline.html">command line utility</A>.
    The first argument is the parameter name or key, and the second argument is the string expression (in single quotes). For example:</P>
 <P><CODE><FONT face="courier, monospaced">Xalan -p param1 'boo' foo.xml foo.xsl</FONT></CODE></P>
 <P>If the string expression includes spaces or other characters that the shell intercepts, first enclose the string in single quotes
    so Xalan-C++ interprets it as a string expression, and then enclose the resulting string in double quotes so the shell interprets it as
    a single argument. For example:</P>
 <P><CODE><FONT face="courier, monospaced">Xalan -p &quot;'hello there'&quot; foo.xml foo.xsl</FONT></CODE></P>

 <P>Performance is much better when Xalan-C++ uses native source tree handling rather than interacting with the Xerces DOMParser.</P>
 <P>If you are using the deprecated DOM, the Xerces DOMParser by default, creates a DOM_XMLDecNode in the DOM tree to represent
    the XML declaration. The Xalan bridge for the Xerces DOM does not support this non-standard node type. Accordingly, you must

   <LI>Set stylesheet parameters. Use the SetStylesheetParam() function.<BR><BR></LI>
   <LI>Compile stylesheets. Use the CompileStylesheet() method to compile a stylesheet, and the TransformToFileCSS() or TransformToDataCSS() function to use the compiled stylesheet in a transformation.<BR><BR></LI>
   <LI>Parse XML sources. Use the XalanParseSource() or XalanParseSouceUseXalan() method.<BR><BR></LI>
   <LI>Place the transformation output in a character array. Use the TransformToData() or TransformToDataCSS() function. After you perform the transformation, use the XalanFreeData() function to free memory allocated for the output data.<BR><BR></LI>
