Re: [xsl] genarate key using a variable

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

I forgot that I needed to send this message in plain text format.  If the 
other one gets through I apologize for the repeat mail...

Original text of my email....

Hey Aruniima,

You've stumbled upon one that puzzled me for awhile.  But I finally came up 
with a quick and easy workaround.  Im sure there are others but this one is 
simple and it works which are my number one rules of coding.

My assumption is that the number of choices the user has as far as node 
names is fairly limited (e.g. Deposits, Withdrawls, etc...) and as such it 
should be a quick and easy task for the xsl:choose element...

heres the xml file...

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="transactions.xslt" ?>
<transactions>
    <deposits>
        <deposit id="001">25.00</deposit>
        <deposit id="002">25.00</deposit>
        <deposit id="003">35.00</deposit>
        <deposit id="004">10.00</deposit>
        <deposit id="005">12.00</deposit>
        <deposit id="006">25.00</deposit>
        <deposit id="007">25.00</deposit>
    </deposits>
    <withdrawals>
        <withdrawal id="001">5.00</withdrawal>
        <withdrawal id="002">2.00</withdrawal>
        <withdrawal id="003">5.00</withdrawal>
        <withdrawal id="004">10.00</withdrawal>
        <withdrawal id="005">12.00</withdrawal>
        <withdrawal id="006">250.00</withdrawal>
        <withdrawal id="007">250.00</withdrawal>
    </withdrawals>
</transactions>



and heres the related xslt file named transactions.xslt....  just change the 
variables accordingly


<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
      xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; >

<xsl:variable name="var_1">deposit</xsl:variable>
<xsl:variable name="var_2">25.00</xsl:variable>
<xsl:key name="varMatch_Deposit" match="//deposit" use="."/>
<xsl:key name="varMatch_Withdrawal" match="//withdrawal" use="."/>

    <xsl:template match="/">

    <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:choose>

    </xsl:template>
</xsl:stylesheet>


Hope this helps.

Best of luck!

M.David
