Import Shopify Variant ID

Hi, how do I import the Variant ID as well? This is critical to our functional needs. Please see the following XML File:

<product>
<id type=”integer”>4392989589562</id>
<title>SW-SM8(SCR) White Shaker HO</title>
<body-html/>
<vendor>Builderz Warehouse</vendor>
<product-type>Cabinets</product-type>
<created-at type=”dateTime”>2020-02-03T08:38:50-07:00</created-at>
<handle>sw-sm8scr-white-shaker-ho</handle>
<updated-at type=”dateTime”>2020-02-03T08:57:05-07:00</updated-at>
<published-at type=”dateTime” nil=”true”/>
<template-suffix/>
<published-scope>global</published-scope>
<tags>Cabinets, Good, Kitchen cabinets, Multifamily</tags>
<variants type=”array”>
<variant>
<id type=”integer”>31312146333754</id>
<product-id type=”integer”>4392989589562</product-id>
<title>Default Title</title>
<price type=”decimal”>19.00</price>
<sku>BW-SW-SM8(SCR)-HO</sku>
<position type=”integer”>1</position>
<inventory-policy>deny</inventory-policy>
<compare-at-price type=”decimal” nil=”true”/>
<fulfillment-service>manual</fulfillment-service>
<inventory-management>shopify</inventory-management>
<option1>Default Title</option1>
<option2 nil=”true”/>
<option3 nil=”true”/>
<created-at type=”dateTime”>2020-02-03T08:38:51-07:00</created-at>
<updated-at type=”dateTime”>2020-02-03T08:57:05-07:00</updated-at>
<taxable type=”boolean”>true</taxable>
<barcode/>
<grams type=”integer”>0</grams>
<image-id nil=”true”/>
<weight type=”float”>0.0</weight>
<weight-unit>lb</weight-unit>
<inventory-item-id type=”integer”>32949173649466</inventory-item-id>
<inventory-quantity type=”integer”>8</inventory-quantity>
<old-inventory-quantity type=”integer”>8</old-inventory-quantity>
<requires-shipping type=”boolean”>false</requires-shipping>
</variant>
</variants>
<options type=”array”>
<option>
<id type=”integer”>5726641193018</id>
<product-id type=”integer”>4392989589562</product-id>
<name>Title</name>
<position type=”integer”>1</position>
<values type=”array”>
<value>Default Title</value>
</values>
</option>
</options>
<images type=”array”/>
</product>

We need this line:

<variant>
<id type=”integer”>31312146333754</id>

How would that work?

Thanks
