我需要删除以下xml中的重复项:

<ListOfRowIDWithListOfBooks xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/">
  <RowIDWithListOfBooks>
    <Row_ID>ADOA-XssK</Row_ID>
    <ListOfBookInfo>
      <book>
        <BookType>Brand</BookType>
        <BookName>jon</BookName>
      </book>
      <book>
        <BookType>Brand</BookType>
        <BookName>jon</BookName>
      </book>
    </ListOfBookInfo>
  </RowIDWithListOfBooks>
</ListOfRowIDWithListOfBooks>

有人可以帮忙吗？
