+We offered you 2 ways to `Update` items into the XMLDB:
+
+## Update attribute
+
+*Syntax:* `public function updateNodeAttribute($table, $oldAttribute, $newAttribute, $forceInsert = false)`
+
+*Params:*
+
+`$table` : String : name of the table
+`$oldAttribute` : Array : name of the actual attribute of the element (it will find the element thanks to it...)
+`$newAttribute` : Array : same but new
+`$forceInsert` : boolean : if the attribute doesn't exist do we create it ?
+
+*Example:*
+
+```php
+$xmldb = new XMLDB('db.xml');
+$xmldb->updateNodeAttribute('table1', array('id', 'links'), array('id', 'zelda'));
+```
+
+## Update child value
+
+*Syntax:* `public function updateNodeValue($table, $attribute = null, $child = null, $value)`
+
+*Example:*
+
+```php
+$xmldb = new XMLDB('db.xml');
+$xmldb->updateNodeValue('table1', array('id', 'notes'), null, 'booga!');
+```
+
+Note : Like in the example, you can also change the item value *but it will erase all children in the process*
