FYI: zypp/parser/HistoryLogReader is now available in git. It reads
specified history log into HistoryItem* structures and for each item
read it calls a function provided in the constructor.

It provides three methods so far:
readAll()
readFrom(Date)
readFromTo(Date,Date)

The callback function gets a HistoryItem::Ptr as argument. This can be
cast into HistoryItemInstall and other subclasses. See zypp/HistoryLogData.h

If you have a suggestion to change this or add new methods, let me know.

Example usage:

- --------8<--------------------------
struct HistoryItemCollector
{
  std::vector<HistoryItem::Ptr> items;

  bool operator()( const HistoryItem::Ptr & item_ptr )
  {
    items.push_back(item_ptr);
    //cout << *item_ptr << endl;
    return true;
  }
};

int main( int argc, const char * argv[] )
{
  HistoryItemCollector ic;
  parser::HistoryLogReader reader(argv[1], boost::ref(ic));

  try
  {
    reader.readFromTo(
      Date("2009-01-01", "%Y-%m-%d"),
      Date("2009-01-02", "%Y-%m-%d"));
  }
  catch (const parser::ParseException & e)
  {
    cout << "error in " << argv[1] << ":" << endl;
    cout << e.asUserHistory() << endl;
  }

  cout << "got " << ic.items.size() << endl;
  return 0;
}
