Question

My output xml should be masked with some elements, based on a variable, flag.If the flag has a value of ‘1’, the output xml should have only the element ‘a'(include all its attributes and child elements). If the flag is 2, output xml should have elements a and b. If it is 3, all the elements and attributes present in the input should be present in the output

my input xml

<Root>

<a ref="t">
<s id="2">value</s>
</a>
<b ref="t">
<s id="2">value</s>
</b>
<c ref="t">
<s id="2">value</s>
</c>
</Root>

my desired output(when flag is 1)

<Root>

<a ref="t">
<s id="2">value</s>
</a>
</Root>
