it say's:
setAny
public void setAny(java.lang.Object value)
Sets the value of the any property. Parameters:value - allowed object is

But I want the root element of my xml document to be the element next in
the ReleaseRequest.Item i.e. advertiseSS
from the document of:
<?xml version="1.0" encoding="UTF-8"?>
<ns1:releaseRequest xmlns="urn:us:gov:dod:army:cerdec:jbfsa:csds:r1"
xmlns:ism="urn:us:gov:ic:ism:v2"
xmlns:ns1="urn:us:gov:dod:army:cerdec:jbfsa:csds:r1"
xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="urn:us:gov:dod:army:cerdec:jbfsa:csds:r1
C:\data\JBFSA\r1\csds_src\config\csds_msgs.xsd">
<ns1:Time>2001-12-17T09:30:47.0Z</ns1:Time>
<ns1:Item>
<ns2:advertiseSS
advertisementID="1b094a9d-063b-409b-8a3b-923061a5c983"
commandDateTime="2006-05-25T09:49:56.593-04:00" userID="peer"
xmlns="
http://mitre.org/DDS" xmlns:ns2="
http://mitre.org/DDS">
...
But I will not know what that element tag is (reason for any). So how
do I create a new object where the contents between my item are a new
document and the next element is the root of that xml document?
ie. new document:
<?xml version="1.0" encoding="UTF-8"?>
<ns2:advertiseSS advertisementID="1b094a9d-063b-409b-8a3b-923061a5c983"
commandDateTime="2006-05-25T09:49:56.593-04:00" userID="peer"
xmlns="
http://mitre.org/DDS" xmlns:ns2="
http://mitre.org/DDS">....
</ns2:advertiseSS>
