Hi Again,

Can you help me with this one ?

The following xsl displays products bought for EACH customer invoice number. The output is sorted by invoice number:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
<xsl:key name="invoiceid" match="/database/invoices/invoices_rec" use="invoiceNum"/>
<xsl:template match="/database">
<html>
<body>
<h2><center>All Customer Invoices</center></h2>
<xsl:for-each select="invoices/invoices_rec[ generate-id(.) = generate-id( key('invoiceid', invoiceNum)[1])]">

<xsl:sort select="invoiceNum" data-type="number" order="ascending"/>
<h3 style = "color: #0000ff">
<p>Ship to:</p>
<p>
<xsl:value-of select="contactName"/><br/>
<xsl:value-of select="shipToAddress"/><br/>
<xsl:value-of select="shipToCity"/><br/>
<xsl:value-of select="shipToState"/><br/>
<xsl:value-of select="shipToZip"/><br/></p>
<p></p>

<p>INVOICE NUMBER: <xsl:value-of select="invoiceNum"/></p>
<p>SALES DATE: <xsl:value-of select="salesDate"/><br/><br/></p>
</h3>

<table border="1" bgcolor="#F5DF91">
<tr bgcolor="#9acd32">
<th>Product ID</th>
<th>Product Name</th>
<th>Product Description</th>
<th>Quantity</th>
<th>Unit Price</th>
<th>Extended Price</th>
</tr>
<xsl:for-each select="key('invoiceid', invoiceNum)">
<tr>
<td><xsl:value-of select="ProductID"/></td>
<td><xsl:value-of select="ProductName"/></td>
<td><xsl:value-of select="ProductDescription"/></td>
<td><xsl:value-of select="Quantity"/></td>
<td><xsl:value-of select="UnitPrice"/></td>
<td><xsl:value-of select="ExtendedPrice"/></td>
</tr>
</xsl:for-each>
</table>
<p style = "color: #ff0000"><em>SubTotal:
<xsl:variable name="subtotal" select="Quantity * UnitPrice"/>
<xsl:text > EUROS </xsl:text>
<xsl:value-of select="$subtotal" />
</em></p><br/>
</xsl:for-each>

<br/>
<br/>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

Q Using this code:

<xsl:variable name="subtotal" select="Quantity * UnitPrice"/>
<xsl:text > EUROS </xsl:text>
<xsl:value-of select="$subtotal" />

I am trying to calculate the the total spent for EACH customer by adding together "Quantity * UnitPrice" for each product purchased.

I am unable to get this to work !

Any help would be appreciated, I have attached the xml source file

Steven,

It looks like that you already have the sub-totals for each item in the "ExtendedPrice" elements

The following should work

<em>
<xsl:text>SubTotal: EUROS </xsl:text>
<xsl:value-of select="sum(key('invoiceid',invoiceNum)/ExtendedPrice)"/>
</em>

Hope this helps

Hi Ivan,

Thanks a lot !

Once again you have solved my problem which means that I should get some sleep tonight, at least until another XSL problem comes along !

Cheers,

bigSteve
