根据大小分割xml元素

Question

给出以下XML示例文件：

<root>
<UserList>
    <UserDetails>
        <Info1>
            <Info1_Id>AA</Info1_Id>
        </Info1>
        <Info2>
            <Info2_Id>BB</Info2_Id>
        </Info2>
    </UserDetails>
    <UserAddress>
        <State>Maharastra</State>
        <AddressDetails>
            <City>Mumbai</City>
            <Address>Andheri Kurla Road, Mumbai</Address>
        </AddressDetails>
    </UserAddress>
    <UserAddress>
        <State>Karnataka</State>
        <AddressDetails>
            <City>Bangalore</City>
            <Address>ITPL Bangalore</Address>
        </AddressDetails>
        <AddressDetails>
            <City>Bangalore</City>
            <Address>XYZ Services Ltd in Whitefield Main Road, Bangalore</Address>
        </AddressDetails>
    </UserAddress>
</UserList>

我想执行XSL转换，以拆分并复制该元素，如果地址长度大于30。如果地址长度大于30，则第一个元素将包含前30个字符，而new（重复的）元素将包含下一个30个字符，依此类推。

预期输出：

<root>
<UserList>
    <UserDetails>
        <Info1>
            <Info1_Id>AA</Info1_Id>
        </Info1>
        <Info2>
            <Info2_Id>BB</Info2_Id>
        </Info2>
    </UserDetails>
    <UserAddress>
        <State>Maharastra</State>
        <AddressDetails>
            <City>Mumbai</City>
            <Address>Andheri Kurla Road, Mumbai</Address>
        </AddressDetails>
    </UserAddress>
    <UserAddress>
        <State>Karnataka</State>
        <AddressDetails>
            <City>Bangalore</City>
            <Address>ITPL Bangalore</Address>
        </AddressDetails>
        <AddressDetails>
            <City>Bangalore</City>
            <Address>XYZ Services Ltd in Whitefield</Address>
        </AddressDetails>
        <AddressDetails>
            <City>Bangalore</City>
            <Address> Main Road, Bangalore</Address>
        </AddressDetails>
    </UserAddress>
</UserList>

如何实现。在此先感谢您的帮助。
