如何将子节点设置为XML的父节点？

Question

I have an XML document in this format:

<EX>
    <file filename="File1">
        <form name="form1"/>
        <form name="form2"/>
        <form name="form3"/>
    </file>
    <file filename="File2">
        <form name="form2"/>
        <form name="form3"/>
    </file>
</EX>

... which I need to convert to this format:

<EX>
    <form name = "form1">
        <file filename="File1"/>
    </form>
    <form name = "form2">
        <file filename="File1"/>
        <file filename="File2"/>
    </form>
    <form name = "form3">
        <file filename="File1"/>
        <file filename="File2"/>
    </form>
</EX>

Can anybody help me with this?

Heres one way you could do it:

loop through your original xml doc and create a new one with a node for each child node in your original doc. Then loop through your original document again, creating corresponding children in your new doc.
