    </text>
  </g>
</svg>

I just want to get the elements which is inside the g element (.i.e flowRoot & text ),

for this i tried :

XElement svg = XElement.Load("path to svg file");
IEnumerable<XElement> elements = svg.Element("g").Elements();

But this is not working. Help me out please?

Try this, your XML uses namespaces:

        XDocument doc = XDocument.Load(<path to file>);
        XNamespace ns1 = "http://www.w3.org/2000/svg";
        //Namespace of a root element can also be retrieved like this:
        //XNamespace ns1 = doc.Root.GetDefaultNamespace();
        var g = doc.Descendants(ns1 + "g").FirstOrDefault();
        if (g != null)
        {
            var flowroot = g.Element(ns1 + "flowRoot");
            var text = g.Element(ns1 + "text");
        }

You should have prefixed name with a namespace:

        IEnumerable<XElement> elements = svg.Element(ns1 + "g").Elements();
