How to store child to child nodes and remove the immediate parent?

[AZH]

We are parsing an xml and after serializing them ,it will be stored in database.Our XML is look like below.\[code\]<SampleTypeService> <Name>sample1</Name> <URL>sample1</URL> <SampleTypeService_PK_ID>225d0266-e83a-44b8-88fc-700f6570d530</SampleTypeService_PK_ID> <SampleTypes> <SampleType_PK_ID>ef1d8c40-72ce-48d8-b252-9b521e96fa74</SampleType_PK_ID> </SampleTypes></SampleTypeService><SampleTypeService> <Name>sample2</Name> <URL>sample2</URL> <SampleTypeService_PK_ID>225reg66-e83a-44b8-88fc-700f6570d530</SampleTypeService_PK_ID> <SampleTypes> <SampleType_PK_ID>gh4d8c40-72ce-48d8-b252-9b521e96fa74</SampleType_PK_ID> </SampleTypes></SampleTypeService>\[/code\]We need to store the value in \[code\]SampleType_PK_ID\[/code\] in a string and then remove both \[code\]SampleTypes\[/code\] and \[code\]SampleType_PK_ID\[/code\] node.I am trying to delete it like below.\[code\]foreach (XmlNode SampleNode in SampleList){ XmlNodeList ChildList = SampleNode.ChildNodes; for (int j = 0; j < ChildList.Count; j++) { if (ChildList[j].LocalName == "SampleType_PK_ID>") { strSampleTypePKID = ChildList[j].InnerText; if (strSampleTypePKID != null) { SampleNode.ParentNode.RemoveChild(ChildList[j]); j--; } } } testString = SampleNode.OuterXml; Console.WriteLine("1):" + strSampleTypePKID); //Code to serialize and store in database is here.}\[/code\]But \[code\]strSampleTypePKID\[/code\] is returning as empty string. What am I missing here. How to take the child to child node value and then delete it along with it's immediate parent?
