我有以下xml文件:

<xfa:data>
  <form1>
    <Page1>
    <Page2>
    <contractInfo> ... </contractInfo>
    <paymentInfo> ... </paymentInfo>
  </form1>
  <commercialType> .... </commercialType>
  <userList> ... </userList>
  <officesList> ... </officesList>
  <commercialType> .... </commercialType>
  <userList> ... </userList>
  <officesList> ... </officesList>
  <commercialType> .... </commercialType>
  <userList> ... </userList>
  <officesList> ... </officesList>
</xfa:data>

我想删除commercialType,userList和officesList节点的每个发生,所以我的输出将是:

<xfa:data>
  <form1>
    <Page1>
    <Page2>
    <contractInfo> ... </contractInfo>
    <paymentInfo> ... </paymentInfo>
  </form1>
</xfa:data>

我怎么能用XSLT做到这一点？

谢谢
