Importing today’s products

First of all, I feel sorry for my English.

I try to import new products from my supplier. Until now I have imported all of them but it is a bit tedious and unnecessary. Therefore, I thought of filtering the XML by date and importing only those of today.

The import is done daily, a couple of times. And the format is as follows:

<product>
  <sku>97609450</sku>
  <updated>2020-09-21 09:16:13</updated>
  <price>54.95</price>
  <title>Logitech G213 Prodigy</title>
</product>
<product>
  <sku>60136991</sku>
  <updated>2020-10-03 07:01:12</updated>
  <price>59.95</price>
  <title>Ghost Of Tsushima</title>
</product>

I’ve been looking around the forum but it’s not clear to me. Is it possible without creating a function?
