Minimum value

Hi,
        My xml is like this...

        <a>
                <value>34</value>
        </a>
        <a>
                <value>23</value>
        </a>
        <a>
                <value>56</value>
        </a>
        <a>
                <value>22</value>
        </a>

Is there a way to find out the "minimum" of "value" with out using xsl:sort
function?

Or

is there a way in which I can form a string like 34:23:56:22: using xsl?


Thank for the help,
Raj..
