functx:replace-element-values
Updates the content of one or more elements
Description
The functx:replace-element-values function takes a sequence of elements and updates their values with the values specified in $values. It keeps all the original attributes of the elements in tact. This is useful if you would like to perform an operation on a sequence of elements, for example, doubling them or taking a substring, without eliminating the elements themselves. The two argument sequences are positionally related; i.e. the first element in $elements takes on the first value in $values, the second element takes on the second value, etc.
