I need to group and count nodes in an xml document with xslt.  I've
read the grouping stuff on the web, but I'm either dumb or lazy and can't
get it to work.  I'm not interested in how to do this generically. 
I'm interested in how to specifically write the xslt that produces the
output below, not generic information about grouping, Muenchen method,
nor anything else.  (I'm lazy :)

Anyway.  I have the following xml.
<page>
	<foo accountID="1" createdDate="10/9/2004 10:20:03 AM"/>
	<foo accountID="2" createdDate="10/9/2004 11:20:03 AM"/>
	<foo accountID="5" createdDate="10/10/2004 10:15:27 AM"/>
	<foo accountID="6" createdDate="10/10/2004 10:14:00 AM"/>
	<foo accountID="7" createdDate="10/12/2004 10:15:27 AM"/>
</page>

I want the output to be like this:

	<table>
		<tr>
			<th>Date Created</th>
			<th>Accounts Created</th>
		</tr>
		<tr>
			<td>10/9/2004</td>
			<td>2</td>
		</tr>
		<tr>
			<td>10/10/2004</td>
			<td>2</td>
		</tr>
		<tr>
			<td>10/12/2004</td>
			<td>1</td>
		</tr>
	</table>

ps.  I've been trying the grouping xslts that I've seen on the web
(with keys and such, but b/c I'm selecting
substring-before(@createdDate, ' ') I can't seem to get it to work.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:key name="createdDate" match="*[@createdDate]"
use="substring-before(@createdDate, ' ')" />
<xsl:template match="foo">
<table>
<tr>
<th>Date Created</th>
<th>Accounts Created</th>
</tr>
<xsl:apply-templates select="*[@createdDate and
generate-id(.)=generate-id(key('createdDate',
substring-before(@createdDate, ' ')))]" />
</table>
</xsl:template>

<xsl:template match="*[@createdDate]">
  <tr>
    <!-- first column is the value of the date attribute -->
    <td><xsl:value-of select="substring-before(@createdDate, ' ')" /></td>
    <!-- second column is the number of records with that date -->
    <td><xsl:value-of select="count(key('createdDate',
substring-before(@createdDate, ' ')))" /></td>
  </tr>
</xsl:template>
</xsl:stylesheet>
