Re: Cast variable to node-set

Ok, here is a sample of what's going on (a bit dumbed down for brevity):

<xsl:variable name="cr_amt"
select="/Transactions/Transaction/CreditAmount"/>
<xsl:variable name="cr_under_amt" select="MinAmt/CRUnderMinAmt"/>

<td style="text-align:right;">
    <xsl:call-template name="displaycurrency">
        <xsl:with-param name="node" select="$cr_amt + $cr_under_amt"/>
        <xsl:with-param name="total">1</xsl:with-param>
    </xsl:call-template>
</td>

Then inside "displaycurrency":

<xsl:variable name="output">
    <xsl:value-of select="sum($node)"/>
</xsl:variable>


The $total xsl:param tells the template to prepend the currency code to the
value (we only show currency code for totals).  The reason for the sum() is
that I can pass either a single node or a node-set.  I always want to sum a
node-set that is passed to the template.  I tried this:

select="$cr_amt | $cr_under_amt"

But that didn't work.  Also, there is one additional requirement, when I
pass a node into the template like this:

<td align="right">
    <xsl:call-template name="displaycurrency">
        <xsl:with-param name="node" select="$cr_under_amt"/>
        <xsl:with-param name="total">1</xsl:with-param>
    </xsl:call-template>
</td>

The node has two attributes, @currency_code and @minor_unit (you've seen
these in my last thread).  What are the chances of getting them into the
template without using seperate params?  I have them set as xsl:param's now:

<xsl:param name="currency_code" select="$node/@currency_code"/>
<xsl:param name="minor_unit" select="$node/@minor_unit"/>


I would prefer to stay away from processor specific extensions.  This
template is used in our application by both MSXML 4.0 and Xalan 2.3.
