Combine 2 nodes into one in XML using XSLT

[AAS]

Hello, I am new to XSLT. Tried hard but want help to combine two nodes using XSLT.
My XML has complex structure.

My Input XML:-

<Root id='1'>
<Nodes>
<Node id="D1">
<name>A1</name>
<Nodes>
<Node id="D1_B1">
<name>ABC</name>
<Nodes>
<Node id="D1_B1_BL1">
<name>ABCL</name>
</Node>
</Nodes>
</Node>
<Node id="D1_B2">
<name>ABC2</name>
<Nodes>
<Node id="D1_B2_BL2">
<name>ABC23</name>
</Node>
</Nodes>
</Node>
</Nodes>
</Node>
<Node id="D2">
<name>B1</name>
<Nodes>
<Node id="D2_B1">
<name>ABC</name>
<Nodes>
<Node id="D2_B1_BL1">
<name>ABCL</name>
</Node>
</Nodes>
</Node>
<Node id="D2_B2">
<name>ABC2</name>
<Nodes>
<Node id="D2_B2_BL2">
<name>ABC23</name>
</Node>
</Nodes>
</Node>
</Nodes>
</Node>
<Node id="D3">
<name>C1</name>
<Nodes>
<Node id="D3_B1">
<name>ABC</name>
<Nodes>
<Node id="D3_B1_BL1">
<name>ABCL</name>
</Node>
</Nodes>
</Node>
<Node id="D3_B2">
<name>ABC2</name>
<Nodes>
<Node id="D3_B2_BL2">
<name>ABC23</name>
</Node>
</Nodes>
</Node>
</Nodes>
</Node>
</Nodes>
</Root>

My desired Output XML should be -:

<Root id='1'>
<Nodes>
<Node id="D2">
<name>B1</name>
<Nodes>
<Node id="D2_B1">
<name>ABC</name>
<Nodes>
<Node id="D2_B1_BL1">
<name>ABCL</name>
</Node>
</Nodes>
</Node>
<Node id="D2_B2">
<name>ABC2</name>
<Nodes>
<Node id="D2_B2_BL2">
<name>ABC23</name>
</Node>
</Nodes>
</Node>
</Nodes>
</Node>
<Node id="D3">
<name>C1</name>
<Nodes>
<Node id="D3_B1">
<name>ABC</name>
<Nodes>
<Node id="D3_B1_BL1">
<name>ABCL</name>
</Node>
</Nodes>
</Node>
<Node id="D3_B2">
<name>ABC2</name>
<Nodes>
<Node id="D3_B2_BL2">
<name>ABC23</name>
</Node>
</Nodes>
</Node>
</Nodes>
<Node id="D1">
<name>A1</name>
<Nodes>
<Node id="D1_B1">
<name>ABC</name>
<Nodes>
<Node id="D1_B1_BL1">
<name>ABCL</name>
</Node>
</Nodes>
</Node>
<Node id="D1_B2">
<name>ABC2</name>
<Nodes>
<Node id="D1_B2_BL2">
<name>ABC23</name>
</Node>
</Nodes>
</Node>
</Nodes>
</Node>
</Node>
</Nodes>
</Root>


I am not able to understand how to group and merge.

Consider to indent your XML samples so that we can identify the structure. And even if don't know how to write the necessary XSLT you will need to explain in plain English which transformation you want to achieve. Just dumping two samples doesn't allow us to see which transformation you want to implement.
