| <FONT color="green">043</FONT> * Implements three extension elements to allow an XSLT transformation to<a name="line.43"></a> |
| <FONT color="green">044</FONT> * redirect its output to multiple output files.<a name="line.44"></a> |
| <FONT color="green">045</FONT> *<a name="line.45"></a> |
| <FONT color="green">046</FONT> * It is accessed by specifying a namespace URI as follows:<a name="line.46"></a> |
| <FONT color="green">047</FONT> * <pre><a name="line.47"></a> |
| <FONT color="green">048</FONT> * xmlns:redirect="http://xml.apache.org/xalan/redirect"<a name="line.48"></a> |

| <FONT color="green">050</FONT> *<a name="line.50"></a> |
| <FONT color="green">051</FONT> * <p>You can either just use redirect:write, in which case the file will be<a name="line.51"></a> |
| <FONT color="green">052</FONT> * opened and immediately closed after the write, or you can bracket the<a name="line.52"></a> |
| <FONT color="green">053</FONT> * write calls by redirect:open and redirect:close, in which case the<a name="line.53"></a> |
| <FONT color="green">054</FONT> * file will be kept open for multiple writes until the close call is<a name="line.54"></a> |
| <FONT color="green">055</FONT> * encountered. Calls can be nested. <a name="line.55"></a> |
| <FONT color="green">056</FONT> *<a name="line.56"></a> |
| <FONT color="green">057</FONT> * <p>Calls can take a 'file' attribute<a name="line.57"></a> |
| <FONT color="green">058</FONT> * and/or a 'select' attribute in order to get the filename. If a select<a name="line.58"></a> |
| <FONT color="green">059</FONT> * attribute is encountered, it will evaluate that expression for a string<a name="line.59"></a> |
| <FONT color="green">060</FONT> * that indicates the filename. If the string evaluates to empty, it will<a name="line.60"></a> |
| <FONT color="green">061</FONT> * attempt to use the 'file' attribute as a default. Filenames can be relative<a name="line.61"></a> |
| <FONT color="green">062</FONT> * or absolute. If they are relative, the base directory will be the same as<a name="line.62"></a> |
| <FONT color="green">063</FONT> * the base directory for the output document. This is obtained by calling<a name="line.63"></a> |
| <FONT color="green">064</FONT> * getOutputTarget() on the TransformerImpl. You can set this base directory<a name="line.64"></a> |
| <FONT color="green">065</FONT> * by calling TransformerImpl.setOutputTarget() or it is automatically set<a name="line.65"></a> |
| <FONT color="green">066</FONT> * when using the two argument form of transform() or transformNode().<a name="line.66"></a> |
| <FONT color="green">067</FONT> *<a name="line.67"></a> |
| <FONT color="green">068</FONT> * <p>Calls to redirect:write and redirect:open also take an optional <a name="line.68"></a> |
| <FONT color="green">069</FONT> * attribute append="true|yes", which will attempt to simply append <a name="line.69"></a> |
| <FONT color="green">070</FONT> * to an existing file instead of always opening a new file. The <a name="line.70"></a> |
| <FONT color="green">071</FONT> * default behavior of always overwriting the file still happens <a name="line.71"></a> |
| <FONT color="green">072</FONT> * if you do not specify append.<a name="line.72"></a> |
| <FONT color="green">073</FONT> * <p><b>Note:</b> this may give unexpected results when using xml <a name="line.73"></a> |
| <FONT color="green">074</FONT> * or html output methods, since this is <b>not</b> coordinated <a name="line.74"></a> |
| <FONT color="green">075</FONT> * with the serializers - hence, you may get extra xml decls in <a name="line.75"></a> |
| <FONT color="green">076</FONT> * the middle of your file after appending to it.<a name="line.76"></a> |
