You can use the delete operator to remove specified elements and attributes, as shown in the following example.
/* Declare an XML variable with a literal XML value. */ var xmlEmployees = <employees> <employee id="111111111"> <firstname>John</firstname> <lastname>Walton</lastname> <age>25</age> </employee> <employee id="222222222"> <firstname>Sue</firstname> <lastname>Day</lastname> <age>32</age> </employee> </employees>; /* * Remove the information about John. */ delete xmlEmployees.employees.employee[0]; /* * Remove the entire <employees> node, leaving an empty XML variable. */ delete xmlEmployees.employees;
Note that when using delete with a path that ends with a filter predicate, you must append the thisXML property, as in the following example:
/* * A delete operation with a predicate expression must end with the thisXML property. */ delete xmlEmployees.employees.employee.(firstname == "John").thisXML;
