Kindly guide me if you have C# parser for dblp.xml or you can guide me regarding this, or about how can we parse huge xml files.

Answer 1

Use XML reader instead of XML dom. XML dom stores the whole file in memory which is totally useless:

Answer 2

You need to use XmlReader

It represents a reader that provides fast, noncached, forward-only access to XML data. Won't load all the data into memory, supposed to be used with large sets of data. Other built in.NET solutions keep the full generated object graph.
