Re: text-to-histogram tool?

Hi Gero,

If you are an XML fan, you can use the ROOT I/O XML driver. To see how it works,
run for instance the small script below
{

   TFile *f = TFile::Open("gero.xml","recreate");    TH1F *h = new TH1F("h","test",100,-3,3);    h->FillRandom("gaus",1000);
   h->Write();
   delete f;
}

You can read it gero.xml in ROOT with

   TFile *f = TFile::Open("gero.xml");
   h->Draw();

If you are not interested by the automatic schema evolution, you do not need to generate
the <StreamerInfos> block at the end of the file.
