Re: [xsl] genarate key using a variable

["M. David Peterson" <conners_dad@xxxxxxx>]

This method should still be effective for you...  However, I am making the 
assumption that the user will first select an attribute they want to sort by 
and then select a value.  Is this not the case?  Or are you saying that they 
can select a value they want to sort by and then select the attribute.  e.g. 
They want to know every transaction that contains the dollar figure $25.00 
or took place on the date 23/04/2004 and have it return deposits, 
withdrawals, etc...  Or is it something entirely different from that which I 
have described...  In any case I would try the following...  Let me know if 
im not understanding the real issue and ill give it some more thought...

Add a "Search_By" param and a "Sort_By" param and then use another 
<xsl:choose> element structure to choose which value to search by and which 
to sort by...

So in other words add the following to the param list..

<xsl:param name="Search_By">Var_1</xsl:param>
<xsl:param name="Sort_By">Var_2</xsl:param>

and the following the the template body...

<xsl:choose>
    <xsl:when test="$Search_By = 'Var_1'">
        <xsl:choose>
            <xsl:when test="$var_1 = 'deposit'">

            <xsl:for-each select="key('varMatch_Deposit', $var_2)">

                Deposit ID: <xsl:value-of select="@id"/><br/>
                Amount: <xsl:value-of select="."/><br/><br/><hr/>

            </xsl:for-each>

            </xsl:when>
            <xsl:when test="$var_1 = 'withdrawal'">

            <xsl:for-each select="key('varMatch_Withdrawal', $var_2)">

                Other ID: <xsl:value-of select="@id"/><br/>
                Other Amount: <xsl:value-of select="."/><br/><br/><hr/>

            </xsl:for-each>

            </xsl:when>
            <xsl:otherwise>

            //code for otherwise

            </xsl:otherwise>
            </xsl:when>
        </xsl:choose>
    <xsl:when test="Search_By = 'Var_2'">

        //code for this option
    </xsl:when>
    <xsl:otherwise>
       // code for otherwise
    </xsl:otherwise>
</xsl:choose>


Best of luck!
