I have been trying to read a XML with the following structure

<TopNode>
<SubNodeType1 Data2="Val2" Data1="Val1"/>
<SubNodeType1 Data2="Val2" Data1="Val1"/>
.
.
n
.
<SubNodeType1 Data2="Val2" Data1="Val1"/>
<SubNodeType2 Data2="Val2" Data1="Val1" Data4="Val4" Data3="Val3"/>
<SubNodeType2 Data2="Val2" Data1="Val1" Data4="Val4" Data3="Val3"/>
</TopNode>

If i try to read this XML data i am able to see all the data from SubNodeType1 in the dataset.

Question is that can i override the dataset to receive all the data in the same dataset. Or any other way in which i can read SubNodeType1 and SubNodeType2 into 2 different datasets?

What I have tried:

XmlDocument xmlFile = new XmlDocument();
xmlFile.Load(strXMLFilePath);
XmlNodeReader xmlReader = new XmlNodeReader(xmlFile);
DataSet ds = new DataSet();
ds.ReadXml(xmlReader, XmlReadMode.InferSchema);
