How to parse XML data and insert to DataSet?

I have a xml string in a variable and I want to get it into a dataset or datatable without having a txt file involved?

Dataset.ReadXml can be done with a XmlReader, and XmlReader can be inputted with a xml string fragment.
Read the example found in documentation below the list of constructors for System.Xml.XmlTextReader - there is the code almost straight off the book for you.
