Also, the value is an _attribute_ of the XML tag. I'm assuming you're attempting to get the value of the attribute which is named value.
The value of a tag would be something like <title>The Bering Sea: A Book About Sea Life </title> It's what is between the tags. An attribute value is different.

Try : "/myData/data[@key='abc']"

Is it this : XmlDocument.GetElementsByTagName Method (System.Xml) | Microsoft Docs[^]

C#

using System;
using System.IO;
using System.Xml;

public class Sample
{
  public static void Main()
  {
    //Create the XmlDocument.
    XmlDocument doc = new XmlDocument();
    doc.Load("books.xml");

    //Display all the book titles.
    XmlNodeList elemList = doc.GetElementsByTagName("data");
    for (int i=0; i < elemList.Count; i++)
    {
      Console.WriteLine(elemList[i].InnerXml);
    }
  }
}
