String Data Extract to Array.

I HAVE A STRING AS FOLLOWS: -

<QuestionTable>
<id>1</id>
<q>WHAT IS OUR NATIONAL FRUIT?</q>
<o1>MANGO</o1>
<o2>ORANGE</o2>
<o3>GUAVA</o3>
<o4>GRAPES</o4>
</QuestionTable>
<QuestionTable>
<id>2</id>
<q>WHAT IS OUR NATIONAL LANGUAGE</q>
<o1>BENGALI</o1>
<o2>TELEGU</o2>
<o3>HINDI</o3>
<o4>ENGLISH</o4>
</QuestionTable>
<QuestionTable>
<id>3</id>
<q>WHAT IS OUR NATIONAL FLOWER</q>
<o1>MARIGOLD</o1>
<o2>TULIP</o2>
<o3>LOTUS</o3>
<o4>ROSE</o4>
</QuestionTable>
<QuestionTable>
<id>4</id>
<q>WHAT IS OUR NATIONAL ANTHEM</q>
<o1>JAI HIND</o1>
<o2>JANAGAMANA</o2>
<o3>WE SHALL OVER COME</o3>
<o4>SARE JAHA SE ACCHA</o4>
</QuestionTable>
<QuestionTable>
<id>5</id>
<q>WHAT IS OUR NATIONAL BIRD</q>
<o1>PIGEON</o1>
<o2>PEACOCK</o2>
<o3>SPARROW</o3>
<o4>CUCKOO</o4>
</QuestionTable>

NOW I WANT TO EXTRACT THE DATA FROM IT AND PUT THAT IN SEPARATE ARRAY FOR EACH TYPE i.e.
string[] qArray,o1Array,o2Array,o3Array,o4Array;
qArray[] will Contain all Data inside <q> and </q>
o1Array[] will Contain all Data inside< o1> and </o1>
etc.
I think splitstring method along with regXwill do that but I cant do that.
Can Anyone Help me.

This should work:
private void button1_Click(object sender, EventArgs e)
{
    string[] qArray = getItemsBetween(txtResult.Text, "<q>", "</q>");
    string[] o1Array = getItemsBetween(txtResult.Text, "<o1>", "</o1>");
    string[] o2Array = getItemsBetween(txtResult.Text, "<o2>", "</o2>");
    string[] o3Array = getItemsBetween(txtResult.Text, "<o3>", "</o3>");
    string[] o4Array = getItemsBetween(txtResult.Text, "<o4>", "</o4>");
}

private string[] getItemsBetween(string input, string before, string after)
{
    List<string> res = new List<string>();

    foreach (string i in input.Split(new string[] { before }, StringSplitOptions.None))
        if (i.Contains(after))
            res.Add(i.Split(new string[] { after }, StringSplitOptions.None)[0]);

    return res.ToArray();
}
