XUpdate Query Compilation Error

[Jayaram Narayana]

hi guys!

given this simple document:

<?xml version = "1.0"?>
<metaKnowledge>
        <metaInfo PID = "1">
                <project
                        name = "open view"
                        UID = "0"
                        documentKey = "open view"
                        fileName = "open view"
                        version = ""
                />
        </metaInfo>
</metaKnowledge>

i need to add a new element inside metaKnowledge. i am trying this XUpdate
query:

<xupdate:modifications version=\"1.0\"
        xmlns:xupdate=\"http://www.xmldb.org/xupdate\";>

        <xupdate:insert-after select=\"metaKnowledge/metaInfo[last()]\">
                <xupdate:update element name=\"project\">
                        <xupdate:attribute 
name=\"name\">MegaProject</xupdate:attribute>
                        <xupdate:attribute name=\"UID\">1</xupdate:attribute>
                        <xupdate:attribute 
name=\"documentKey\">MegaProject</xupdate:attribute>
                        <xupdate:attribute 
name=\"fileName\">MegaProject</xupdate:attribute>
                        <xupdate:attribute 
name=\"version\">null</xupdate:attribute>
                        A New Project Called MegaProject
                </xupdate:element>
        </xupdate:insert-after>
</xupdate:modifications>

can someone tell me if this query is formed right? if not, what's the right
query? i am always getting this error, try what i may:

org.xmldb.api.base.XMLDBException: Query Compilation Error
        at org.apache.xindice.core.FaultCodes.createXMLDBException(Unknown
Source)
                        :
                        :

any help appreciated greatly!

TIA,
