+<h1>Database Export Class</h1>
+
+<p>The Database Utilities Class contains functions that help you export your data.</p>
+
+<p class="important"><strong>Important:</strong> This class must be initialized independently since it is a separate class from the main Database class.
+More info below...</p>
+
+
+<h2>Initializing the Export Class</h2>
+
+<p>To initialize this class please use the following code:</p>
+
+<code>$this->load->dbexport()</code>
+
+<p>You can also autoload this class from within your <dfn>config/autoload.php</dfn> file by specifying <kbd>dbexport</kbd> in the <samp>$autoload['libraries']</samp> array.</p>
+
+<p>Once initialized you will access the functions using the <dfn>$this->dbexport</dfn> object:</p>
+
+<code>$this->dbexport->some_function()</code>
+
+
+
+<h2>$this->dbexport->cvs_from_result($db_result)</h2>
+
+<p>Permits you to generate a CVS file from a query result. The first parameter of the function must contain the result object from your query.
+Example:</p>
+
+<code>
+$this->load->dbexport();<br />
+<br />
+$query = $this->db->query("SELECT * FROM mytable");<br />
+<br />
+echo $this->dbexport->cvs_from_result($query);
+</code>
+
+<p>The second and third parameters allows you to
+set the delimiter and newline character. By default tabs are used as the delimiter and "\n" is used as a new line. Example:
+
+<code>
+$delimiter = ",";<br />
+$newline = "\r\n";<br />
+<br />
+echo $this->dbexport->cvs_from_result($query, $delimiter, $newline);
+</code>
+
+<p class="important"><strong>Important:</strong> This function will NOT write the CVS file for you. It simply creates the CVS layout.
+If you need to write the file use the <a href="../helpers/file_helper.html">File Helper</a>.</p>
+
+
+
+<h2>$this->dbexport->xml_from_result($db_result)</h2>
+
+<p>Permits you to generate an XML file from a query result. The first parameter expects a query result object, the second
+may contain an optional array of config parameters. Example:</p>
+
+<code>
+$this->load->dbexport();<br />
+<br />
+$query = $this->db->query("SELECT * FROM mytable");<br />
+<br />
+$config = array (<br />
+ 'root' => 'root',<br />
+ 'element' => 'element', <br />
+ 'newline' => "\n", <br />
+ ';tab' => "\t"<br />
+ );<br />
+<br />
+echo $this->dbexport->cvs_from_result($query, $config);
+</code>
+
+<p class="important"><strong>Important:</strong> This function will NOT write the CVS file for you. It simply creates the CVS layout.
+If you need to write the file use the <a href="../helpers/file_helper.html">File Helper</a>.</p>
