[XML-SIG] setAttribute DOM question-newbie

[Guy Robinson]

Hello,

 Trying to create a ODBC table -> xml ->(eventually) 4SS script and having
the following problem with setattribute. I would like each field value to be
 an elements attribute but I can't get
new_elem.setAttribute(QryAttrName[i] ,row[i] )
to work .I can't see what's wrong with it (see complete code below).
The traceback is:

  new_elem.setAttribute(QryAttrName[i] ,row[i] )
  File "C:\PYTHON21\_xmlplus\dom\Element.py", line 98, in setAttribute
     raise SyntaxErr()
 xml.dom.SyntaxErr: Specified string is invalid or illegal

 What don't I understand? TIA

 Guy

     DbRec = DbCur.fetchall()
     for row in DbRec:
         new_elem = doc.createElement( 'item')
         for i in range(len(row)):
             new_elem.setAttribute(QryAttrName[i] ,row[i] ) #<------
             print QryAttrName[i], "=", row[i]
         doc_elem.appendChild(new_elem)

     xml.dom.ext.PrettyPrint(doc)
