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,
                                   TextmlConstants.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: print the version info.
   // * Failure: print the error message.
   for (int i = 0; i < documents.Length; ++i)
   {
       if (documents[i].Error != null)
           {
               Console.WriteLine(documents[i].Error);
           }
   else
   // Display the name and version number of this document, followed by the
   // version number of each previous version that is still stored in the docbase.
   {
       Console.Write
          (String.Format("\nDocument: {0}" +
                         "\n  Current version number: {1}" +
                         "\n  Number of previous versions retained: {2}",
                         documents[i].Document.Name,
                         documents[i].Document.Version,
                         documents[i].Document.PreviousVersionList.Count));
   
       // If there are any previous versions of the document, display their
       // version numbers as a list.
       if (documents[i].Document.PreviousVersionList.Count > 0)
       {
           Console.WriteLine("\n  Version numbers (of the previous versions):");
   
           for (int j = 0;
                j < documents[i].Document.PreviousVersionList.Count; ++j)
           {
               Console.Write
                   (String.Format("  {0} ",
                    documents[i].Document.PreviousVersionList[j]));
           }
       }
       Console.WriteLine("");
   
   }  // End of else block
   }  // End of for loop
