XML Galore: Replacement for INI files

[kovan]

here are some functions that might come in handy

here is XML file before changes

<?xml version="1.0" standalone="no"?>
<ProgramSettings>
  <Lingo>German</Lingo>
</ProgramSettings>

here are 2 lines of code, one to set a new value, and the other to read the value..

MessageBox.Show(myXML.setXMLNodeInXMLFile(Environment.CurrentDirectory + @"\settings.xml", "ProgramSettings", "Lingo", "Spanish"));
MessageBox.Show(myXML.getXMLNodeFromXMLFile(Environment.CurrentDirectory  + @"\settings.xml", "ProgramSettings", "Lingo"));

here is the result

<?xml version="1.0" standalone="no"?>
<ProgramSettings>
  <Lingo>Spanish</Lingo>
</ProgramSettings>

and here is the code
