Deserialize XML up to a CERTAIN point

Question

I have an XML file which contains 1) a serialized object and 2) a serialized hashtable. Here is my pseudo xml file(data.xml):

   //PROPERTIES of an object called "Information"
   <?xml version="1.0" encoding="utf-8"?>
   <Information xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <CompileScript>false</CompileScript>
   <SaveScript>false</SaveScript>
   <ConvertPaths>false</ConvertPaths>
   <UseUninstaller>true</UseUninstaller>
   <UninstallSuccess>[NAME] was successfully removed from your computer.  </UninstallSuccess>
   <UninstallPrompt>Are you sure you want to completely remove [NAME] and all of its components?</UninstallPrompt>
   <AllowChangeStartMenuFolderName>false</AllowChangeStartMenuFolderName>
   //... (many others)
  //Here starts KEYS & VALUES of my hashtable
   <entry>
  <fileName> My file name 1</fileName>
  <instDir>My file location 1</instDir>
  </entry>
  <entry>
  <fileName> My file name 2</fileName>
  <instDir>My file location 2</instDir>
  </entry>
  //...and so on.

My goal is to deserialize half of the XML file (up to "AllowChangeStartMenuFolderName") back to "Information" object and the remaining part back to a hashtable. My concerns:

1. How do I tell the program to deserialize the file up to "AllowChangeStartMenuFolderName" and then STOP?
2. How do I tell the program to start deserializing at a certain point of an XML file(starting from the "entry" tag and down to the end of the file)?

Can somebody at least put me in the right direction, I haven't found any information on the internet. Thanks

EDIT

I have tried :

   XmlTextReader reader = new XmlTextReader("...Path...\\data.xml");
   //the last element before the keys and values of a hashtable start
   reader.ReadToDescendant("AllowChangeStartMenuFolderName");
   XmlSerializer serializer = new XmlSerializer(typeof(Classes.Information));
   //info is a new empty object which should be filled with values from the XML file
   this.info = (Classes.Information)serializer.Deserialize(reader.ReadSubtree());
            reader.Close();

Throws me an exception at the last line - "Error in XML Document (27,4)".

My original XML (the first one was pseude code):

 <?xml version="1.0" encoding="utf-8"?>
 <Information xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
 <CompileScript>false</CompileScript>
 <SaveScript>false</SaveScript>
 <ConvertPaths>false</ConvertPaths>
 <UseUninstaller>true</UseUninstaller>
 <UninstallSuccess>[NAME] was successfully removed from your computer.</UninstallSuccess>
 <UninstallPrompt>Are you sure you want to completely remove [NAME] and all of its components?</UninstallPrompt>
 <AllowChangeStartMenuFolderName>false</AllowChangeStartMenuFolderName>
 <StartMenuShortcut>true</StartMenuShortcut>
