Input xml:

<?xml version="1.0" encoding="UTF-8"?>
<Order>
	<OrderLines>
		<OrderLine ChangeInOrderedQty="1">
			<Item ItemID="Item_1"/>
			<Extn ExtnLineNumber="1"/>
			<StatusBreakupForCanceledQty>
				<CanceledFrom OrderReleaseKey="1111" Status="cancel">
					<Details ShipNode="150"/>
				</CanceledFrom>
			</StatusBreakupForCanceledQty>
		</OrderLine>
	</OrderLines>
	<OrderLines>
		<OrderLine ChangeInOrderedQty="4">
			<Item ItemID="Item_2"/>
			<Extn ExtnLineNumber="2"/>
			<StatusBreakupForCanceledQty>
				<CanceledFrom OrderReleaseKey="1121" Status="cancel">
					<Details ShipNode="150"/>
				</CanceledFrom>
			</StatusBreakupForCanceledQty>
		</OrderLine>
	</OrderLines>
	<OrderLines>
		<OrderLine ChangeInOrderedQty="6">
			<Item ItemID="Item_3"/>
			<Extn ExtnLineNumber="3"/>
			<StatusBreakupForCanceledQty>
				<CanceledFrom OrderReleaseKey="1111" Status="cancel">
					<Details ShipNode="150"/>
				</CanceledFrom>
			</StatusBreakupForCanceledQty>
		</OrderLine>
	</OrderLines>
	<OrderLines>
		<OrderLine ChangeInOrderedQty="2">
			<Item ItemID="Item_5"/>
			<Extn ExtnLineNumber="4"/>
			<StatusBreakupForCanceledQty>
				<CanceledFrom OrderReleaseKey="1111" Status="cancel">
					<Details ShipNode="100"/>
				</CanceledFrom>
			</StatusBreakupForCanceledQty>
		</OrderLine>
		<OrderLines>
			<OrderLine ChangeInOrderedQty="3">
				<Item ItemID="Item_5"/>
				<Extn ExtnLineNumber="5"/>
				<StatusBreakupForCanceledQty>
					<CanceledFrom OrderReleaseKey="1121" Status="cancel">
						<Details ShipNode="150"/>
					</CanceledFrom>
				</StatusBreakupForCanceledQty>
			</OrderLine>
			<OrderLine ChangeInOrderedQty="4">
				<Item ItemID="Item_5"/>
				<Extn ExtnLineNumber="6"/>
				<StatusBreakupForCanceledQty>
					<CanceledFrom OrderReleaseKey="1121" Status="cancel">
						<Details ShipNode="100"/>
					</CanceledFrom>
				</StatusBreakupForCanceledQty>
			</OrderLine>
		</OrderLines>
	</OrderLines>
</Order>

Output xml:
Need to group orderlines based orderReleaseKey and ship node should be 150.

<?xml version="1.0" encoding="UTF-8"?>
<OrderReleaseList>
    <OrderReleaseDetail OrderReleaseKey="1111">
        <OrderLines>
            <OrderLine ChangeInOrderedQty="1">
                <Item ItemID="Item_1" />
                <Extn ExtnLineNumber="1" />
            </OrderLine>
        </OrderLines>
        <OrderLines>
            <OrderLine ChangeInOrderedQty="6">
                <Item ItemID="Item_3" />
                <Extn ExtnLineNumber="3" />
            </OrderLine>
        </OrderLines>
      <OrderReleaseDetail>
   <OrderReleaseDetail OrderReleaseKey="1121">
    <OrderLines>
            <OrderLine ChangeInOrderedQty="3">
                <Item ItemID="Item_5" />
                <Extn ExtnLineNumber="5" />
            </OrderLine>
        </OrderLines>
</OrderReleaseList>

See Muenchian grouping:

Your filter on your nodes should be in your key and for-each.
