Parsing XML with t-SQL in two separate tables

Usign SQL 2012 and trying to parse an XML to 2 separate tables in my database. Normaly 1 table would be enough, but not in this instance. My XML is structured as follows (I can't change it's structure, I already recieve it like that)

  <?xml version="1.0" encoding="utf-8" standalone="yes" ?> 
  <podjetje id="" storitev="" uporabnik="" ts="" opis_storitve="">
  <izdelki>
  <izdelek st="1">
      <izdelekID>ID</izdelekID> 
      <ean>EAN CODE</ean> 
      <izdelekIme>PRODUCT NAME</izdelekIme> 
      <url>WEBSITE</url> 
      <kratkiopis>SHORT DESCRIPTION</kratkiopis> 
      <opis>DESCRIPTION</opis> 
      <dodatneLastnosti>ATTRIBUTES</dodatneLastnosti> 
      <slikaVelika>BIG PICTURE URL</slikaVelika> 
      <dodatneSlike>
          <dodatnaSlika1>EXTRA IMAGE URL</dodatnaSlika1> 
          <dodatnaSlika2>EXTRA IMAGE URL2</dodatnaSlika2> 
          <dodatnaSlika3>EXTRA IMAGE URL3</dodatnaSlika3> 
      </dodatneSlike>
  </izdelek>
  </izdelki>
  </podjetje>

To insert this XML into a table i use SQL bulk insert

SET @SQLString = 'INSERT INTO tmpImport(XmlCol)
    SELECT * FROM OPENROWSET(BULK ''' + @ImportFileName + ''', SINGLE_BLOB, ERRORFILE = ''' + @BulkLoadFilePath + ''') AS x '
EXECUTE (@SQLString)

I can handle most of the data without any problems. I ran into some problems when i get to the node "dodatneSlike". The idea is, that each article has some pictures. The main picture is in the node "slikaVelika" and I can insert it into my table. There are extra pictures in the child nodes of node "dodatneSlike". This is causing me problems, because I have to insert these extra pictures into a separate table (inserting the picture from node "slikaVelika" would also help, but I think i can get around it if it's not possible). The table is nothing special, just the Article ID from node "izdelekID" and the pictures from "dodatneSlike".

The problem is, I never know how many nodes ("dodatnaSlika1", "dodatnaSlika2",...) there will be. There might be 1, 10, 0....

So my question is how do I get the values from "dodatnaSlika" nodes?
