Read xml node value from the xml file without loading the file

[C# Programming]

Hi, I have a xml file with more than 1 GB size. I have to read the xml node value from the xml file. I can load the xml file and then read the value of node, but If I load the file its decrease the performance of the application. Is there any other method by which I can read the node value without loading the xml file ?
