The current node (or context node ) of a document tree is the node that the XSLT processor is on during its walk through the tree. However, dont confuse the current node with the selected node or nodes. The current node is the starting point for the XSLT processor for a given location step (an XPath expression used to retrieve nodes from a source tree), but it is the location step that actually determines what node or set of nodes is actually selected.
