Subject: Adding the content of an element and displaying the total

Code examples below...

I have a customer who has a jBidWatcher auctions.xml with about four years of auction information stored within. I put together a little xsl stylesheet to extract the information from the auctions.xml and present the info in a more readable format. He likes what I have put together so far, but would like a summary at the bottom of the page which shows totals.

What I want to do is create a loop that:

1 - Checks for the highbidder to be equal to w9evt1
2 - If highbidder equal to w9evt1 then grab value of currently price element
3 - loop again and keep adding together value of currently price until we have added all the possible prices on all the auctions that w9evt1 won.
4 - Display the output

Code below...

Thanks for any help!

Well, looks like I figured out a method to do this... problem is, it requires the exslt common extension... which does not work nicely with firefox 2.x.

Firefox 3 beta 2 seems to work fine with the exsl extensions, but my customer does not have that and my webhost is on unix and I am not sure how do server side xml translation with php. Anyone have a better solution for me?

So here's a code snippet of working code....

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:exsl="http://exslt.org/common"
extension-element-prefixes="exsl"
version="1.0">

<xsl:variable name="bidder" select="'w9evt1'" />

<xsl:template match="/">
<html>
<body>
<xsl:variable name="subTotals">
<xsl:for-each select="auctions/info">
<xsl:choose>
<xsl:when test="highbidder=$bidder">
<number><xsl:value-of select="currently/@price"/></number>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:variable>

<p>Total Price = <xsl:value-of select="format-number(sum(exsl:node-set($subTotals)/number),'#.00')"/></p>

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

This does not seem to have much to do with Stylus Studio,
and this is the Stylus Studio support forum.

For questions like this, you might find the general-purpose
XSL-LIST run by Mulberry Technologies to be much more useful.

You might also try the Mozilla public development forums.
