To create an XPath function by dragging it to the target tree

  1. If the Components window is not visible, select Window > Components from the Oracle JDeveloper menu bar.

  2. In the Components window, select General XPath or Advanced XPath. Select a category of functions, for example, String Functions.

  3. Drag the desired function from the Components window to the target tree node (Map View), or XSLT tree node (XSLT View), to which the function is to be assigned. A green highlight appears to the left of the target/XSLT tree node.

  4. Drop the function while the green highlight is visible.

    The function is created in the canvas pane and linked to the target/XSLT node where the function was dropped.

  5. If the function requires parameters, edit the parameters using one of the methods discussed in How to Modify an Existing Function XPath Expression in the Canvas Pane.
