XQuery err:XPST0003

Question

Hello,
I need help. I have the following query
define variable $packets {collection("nettraffic.bdbxml")/packet};
for $i in $packets
return
<packet>
     <mac>{$i/proto[@name="ethernet"]/field[@name="src"]/@showvalue}</mac>
     <ip>{$i/proto[@name="ip" or @name="ipv6"]/field[@name="src"]/@showvalue}</ip>
</packet>and the following code in C++:
dbPath = config_manager->LoadDatabaseLocation();
          container = manager->openContainer(dbPath.c_str(), DBXML_TRANSACTIONAL | DBXML_ALLOW_VALIDATION |
                                                      DBXML_INDEX_NODES | DB_THREAD, XmlContainer::NodeContainer);
          XmlQueryContext context = manager->createQueryContext();
          std::string myQuery = query_str.c_str();
          XmlResults results = manager->query(myQuery, context);
          XmlValue value;
          std::string docContent = "<?xml version=\"1.0\" encoding=\"ISO-8859-1\" ?> \n<packets>";
          while (results.next(value))
               docContent += "\n" + value.asString();
          docContent += "\n</packets>";and I get the the error [XPST0003]. What am I doing wrong? How can I save the query results in an xml file for further processing ?
Please help me ! Thanks in advance,
Adina

Hi Adina,
You are using incorrect XQuery syntax. You didn't give the line and column for the error you got, but from looking at your query it seems to be the global variable declaration, which should look like this:
define variable $packets := collection("nettraffic.bdbxml")/packet;John
