for extending and simplifying what you can do with an XLST processor like
Xalan. With input and contributions from the XML open-source developer community, we are working on

extension class is <A href="apidocs/org/apache/xalan/lib/Extensions.html">
org.apache.xalan.lib.Extensions</A>. Some extension
functions (e.g. intersection, difference, etc.) used to be in this class are now moved to the

<P>If you are calling Xalan-Java-supplied extensions, we recommend that you define the corresponding 
namespace in your stylesheet, and call the extension using the namespace prefix that you have associated 
with that namespace. That way, if we later reorganize how the Xalan-Java-supplied extensions are stored, 
you won't have to modify your stylesheet.</P>

<P>A standard XSL transformation involves an XSL stylesheet, an XML source tree, and the transformation
result tree. The transformation sends the entire result to a single 
<A href="apidocs/javax/xml/transform/Result.html">javax.xml.transform.Result</A> object.</P> 
<P>The namespace for the <A href="apidocs/org/apache/xalan/lib/Redirect.html">Redirect</A> 
extension is:</P>
<P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<CODE><FONT face="courier, monospaced">http://xml.apache.org/xalan/redirect</FONT></CODE></P>
<P>It supplies three extension elements that you can use to redirect portions of your transformation 
output to multiple files: &lt;open&gt;, &lt;write&gt;, and &lt;close&gt;. If you use the &lt;write&gt; 
element alone, the extension opens a file, writes to it, and closes the file immediately. If you want 
explicit control over the opening and closing of files, use &lt;write&gt; in conjunction with 
the &lt;open&gt; and &lt;close&gt; elements.</P>
<P>The &lt;open&gt; and &lt;write&gt; elements include a file attribute and/or a select attribute to 
designate the output file. The file attribute takes a string, so you can use it to directly specify 
the output file name. The select attribute takes an XPath expression, so you can use it to dynamically 
generate the output file name. If you include both attributes, the Redirect extension first evaluates 
the select attribute, and falls back to the file attribute if the select attribute expression does 
not return a valid file name.</P>
<P>The &lt;open&gt; and &lt;write&gt; elements also support an append attribute. If the append attribute 
is set to true or yes, then the result is appended to the output file.</P>

<P>
 The SQL extension provides extension functions for connecting to a JDBC data source, 
 executing a query, and working incrementally through a &quot;streamable&quot; result set. Streaming 
 (reuse of a single row node to traverse the result set) is the default mode of operation. 
 if you want unlimited access to the entire result set, you can cache the query result set 
 (1 row node for each row in the result set).</P>
<P><B>If you use streaming mode (the default), you can only access row elements one at a time 
 moving forward through the result set. The use of XPath expressions in your stylesheet, for 
 example, that attempt to return nodes from the result set in any other manner may produce 
 unpredictable results.</B></P>

<P>To define a parameterized query, use a SQL query string with a question mark (?) for each 
parameter. You can provide the parameter values at runtime with stylesheet parameters or with 
nodes in the XML source document. 
For each parameter, you should also designate the SQL data type.</P>
<P>XConnection provides a number of addParameter() methods and an addParameterFromElement() method 
that you can use as extension functions to pull in the parameter values (in the order the 
parameters appear in the query). To execute the query and return the result set, call the pquery() 
method as an extension function. There are two variations of the pquery() method. The one you 
should ordinarily use includes as arguments the SQL query string and a string list 
(delimited by the space, tab, or line feeds) of parameter types. For example:</P>

the pipeDocument extension element pipes an XML document through a series of one or more 
transformations. The output of each transformation is piped to the next transformation. The 
final transformation creates a target file.</P>

<P>Suppose, for example,you have a stylesheet that is processing a &quot;book&quot; document with elements 
designating the documents to be transformed. This primary stylesheet generates a table of 
contents for the book. For each source document it uses a pipeDocument extension element to pipe 
the document through a series of one or more transformations.</P>
