auto increment seq num

[agsp123]

Depending on the distinct value of "type" in the following xml I need to generate a sequence number and add that to the resulting xml.

For. If there are two distinct "type" elements then
"sequence number" should be 1 for the first one
and 2 for the second type.
<Sample>
<num>5700</num>
<MAIN>
<type>1101</type>
<SUB>
        <text>aaa</text>
</SUB>
</MAIN>
<MAIN>
<type>1102</type>

<SUB>
    <text>bbbb</text>
</SUB>
</MAIN>
<MAIN>
<trans_type>1101</trans_type>
<SUB>
    <text>cccc</text>
</SUB>
</MAIN>
</Sample>


Result should be as follows:
<Sample>
<num>5700</num>
<MAIN>
<type>1101</type>
<sequencenum>1</<sequencenum>
<SUB>
        <text>aaa</text>
</SUB>
</MAIN>
<MAIN>
<type>1102</type>
<sequencenum>2</<sequencenum>
<SUB>
    <text>bbbb</text>
</SUB>
</MAIN>
<MAIN>
<trans_type>1101</trans_type>
<sequencenum>1</<sequencenum>
<SUB>
    <text>cccc</text>
</SUB>
</MAIN>
</Sample>

Please let me know how to get the result in xslt.
I tried using count and number but did not got the answer.
Any help is highly appreciated.
