==New Expressions==
<p>The XQUF offers five new expressions to modify data. While insert, delete, rename and replace basically explain themselves, the transform expression is different. Modified nodes are copied in advance and the original databases remain untouched. </p>
==Examples==
An expression consists of a target node (the node we want to alter) and additional information like insertion nodes, a QName, etc. which depends on the type of expression. You can find a few examples and additional information below.
