XSLT IllegalAddException problem

[justin mcsporran]

Hi,
This problem's got me bamboozled, so if anyone can help, I'd be really grateful.
I have a pretty simple xml document (in a dom4j Document object):

<?xml version="1.0"?>
<item itemID="2299" layer="0" isSelected="false" isOpen="true">
<item itemID="2390" layer="1" isSelected="false" isOpen="false"/>
<item itemID="2391" layer="1" isSelected="false" isOpen="false"/>
<item itemID="2392" layer="1" isSelected="false" isOpen="false"/>
<item itemID="2393" layer="1" isSelected="false" isOpen="false"/>
<item itemID="2394" layer="1" isSelected="false" isOpen="false"/>
</item>

To this I'm applying the following xsl, with the aim of printing a table of just two attributes
from each of the <item> elements in the document(irrespective of whether the elements are
parents, children, etc... since they are all <item>s):

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
        <p>Items</p>
        <table border="1">
        <tr bgcolor="#9acd32">
                <th>itemID</th><th>isOpen</th>
        </tr>
        <xsl:for-each select="item">
                <tr>
                        <td><xsl:value-of select="@itemID"/></td>
                        <td><xsl:value-of select="@isOpen"/></td>
                </tr>
        </xsl:for-each>
        </table>
</xsl:template>
</xsl:stylesheet>

However, I get the following exception when I run it:

; SystemID: file:///home/brent/usr.local/tomcat/webapps/ROOT/WEB-INF/stylesheets/mstree.xsl; Line#: 6; Column#: 24 javax.xml.transform.TransformerException: org.dom4j.IllegalAddException: The node "org.dom4j.tree.DefaultElement@7e4c97 [Element: 
]" could not be added to the branch "null" because: Cannot add another element to this Document as it already has a root element of: p at org.apache.xalan.transformer.TransformerImpl.executeChildTemplates
...and so on.

Any ideas as to where I'm going wrong would be really appreciated.
Thanks,
Justin
