How to retrieve a value as int or change a string to int?

I'm trying to create a web counter, I'm fairly new to XML. I created a file
called counter.xml.

It looks like so.

<?xml version="1.0" encoding="utf-8" ?>
<counter>
<Page>
<Name>default</Name>
<Hit>2000</Hit>
</Page>
<counter/>

I just want to be able to retrieve the hit value and increment it by one and
write the value back to <Hit>

Here's what I've come up with so far.

Dim myDoc As New XmlDocument
Dim objPageElem As XmlElement
Dim strHit As String

myDoc.Load(Server.MapPath("counter.xml"))

objPageElem = myDoc.SelectSingleNode("//Page[Name='default']/Hit")
strHit = objPageElem.InnerXml

I get the value but as you see it's a string. I need it as an Int to
increment it and then write it back to the file.

Any input would be appreciated.

You may want Int32 class. Something like,

string s="1";
int i=Int32.Parse(s) + 1;

Thank Han, I'll give that a try.
