One of the questions asked last week was whether XMLBeans could be used for insert and update and delete. Here is the answer....

You use an XmlCursor instance to navigate through and manipulate an XML instance document. Once you obtain an XML document, you can create a cursor to represent a specific place in the XML. Because you can use a cursor with or without a schema corresponding to the XML, cursors are an ideal way to handle XML without a schema. You can create a new cursor by calling the newCursor method exposed by an object representing the XML, whether it was parsed into a strong type compiled from schema or an XmlObject (as in the no-schema case).

With an XmlCursor, you can also:

• Execute XQuery expressions against the XML with the execQuery method.
• Edit and reshape the document, inserting, moving and removing XML.
• Insert bookmarks that "stick" to the XML at the cursor's position even if the cursor or XML moves.
• Get and set values for containers (elements and whole documents), attributes, processing instructions, and comments.
