Generating a list of document versions

Iterating through multiple versions of multiple documents retrieved from one docbase.

1. Write a query to retrieve a list of one or more documents.
   For the SampleNewsDocbase, you can use sample query AllNonSystemDocumentsQuery.xml to return a list of all documents in the docbase.
2. Run the query, and store the list in an array:

   
   IxiaDocumentServices.Result [] 
       documents = docServices.GetDocuments
                                      (subList,
                                       Constants.TEXTML_DOCUMENT_VERSIONS_LIST);
   

3. For each document in the list, get and display: the name of the document; the version number of the document's current version; and a list of the previous version numbers (if any):

   
   // Process each document.
   // Either:
   // * Success: display the version info.
   // * Failure: display an error message.
   for (int i = 0; i < documents.length; ++i)
   {
       if (documents[i].error != null)
       {
           System.out.println(documents[i].error);
       }
       else
       {
           System.out.format ("Document: %s" +
                        "\n  Current version number: %d." +
                        "\n  Number of previous versions retained: %d",
                        documents[i].document.GetName(),
                        documents[i].document.GetVersion(),
                        documents[i].document.GetPreviousVersionList().length);
   
           // If there are any previous versions of the document, display their
           // version numbers as a list.
           if (documents[i].document.GetPreviousVersionList().length > 0)
           {
               System.out.println
                    ("\n  Version numbers (of the previous versions):");
               for (int j=0;
                    j<documents[i].document.GetPreviousVersionList().length; ++j)
               {
                   System.out.format ("    %d ",
                               documents[i].document.GetPreviousVersionList()[j]);
               }
           }
           System.out.println("");
           System.out.println("");
   
       }  // End of else block
   }  // End of for loop
