[xsl] referring to previous elements

[Senthilkumar Arunachalam <senthilkumar.arunachalam@xxxxxxxxxxxxxxx>]

Hello,
   In the following XML , i would like to have the value of the previous

element in a "xsl:variable".can anybody give me a solution.

<durs>
    <actions>
        <action>
            <adq>ADQ1</adq>
            <subadq>SADQ1</subadq>
        </action>
        <action>
            <adq>ADQ2</adq>
            <subadq>SADQ2</subadq>
        </action>
        <action>
            <adq>ADQ3</adq>
            <subadq> SADQ3</subadq>
        </action>
    </actions>
</durs>

In the above XML, i would like to do a test whether "ADQ1 != ADQ2".

How can this be done using XSL.i tried using xsl:variable, but couldn't
achieve.

Regards,
Senthil.
