Question

I would like to know how I could generate code from a text file in a particular format into a VB.net or C# source file.
For instance: I would like my code generating program to read text file having the following format:

<category1>
      <subcategory>
        entry1
        entry2
      </subcategory>
</Category1>

And then generate code in vb.net(or C#):

Dim TreeNode1 As System.Windows.Forms.TreeNode = New System.Windows.Forms.TreeNode("entry1") 
Dim TreeNode2 As System.Windows.Forms.TreeNode = New System.Windows.Forms.TreeNode("entry2") 
Dim TreeNode3 As System.Windows.Forms.TreeNode = New System.Windows.Forms.TreeNode("subcategory", New System.Windows.Forms.TreeNode() {TreeNode1, TreeNode2})

The idea is to compile the main code after the user have modified the txt file and used the code generating program. I would prefer to write the code generating program in C, python or C#.
How can I go about this?

I’m not really convinced this is a python question, despite the tags and penultimate sentence in the question, but here’s a python answer.

>>> from xml.etree import ElementTree as etree
>>> corpus = '''<category1>
...       <subcategory>
...         entry1
...         entry2
...       </subcategory>
... </category1>
... '''
>>> doc = etree.fromstring(corpus)
>>> for subcategory in doc.getchildren():
...     for entry in filter(bool,
...                         map(str.strip,
...                             subcategory.text.split('\n'))):
...         print "entry output: (%s)" % entry
...     print "subcategory output (%s)" % subcategory.tag
... 
entry output: (entry1)
entry output: (entry2)
subcategory output (subcategory)
