Pasting syntax-highlighted code

I just found this guide on pasting syntax highlighted code (escaped with this form) into Blogger blogs. It's probably not all that useful, but anyway, let's give it a go with a function I use to read a binary file output by xmds into Python:

def read_file(indat_fname, xsil_fname):
   # get datafile name and precisions
   if got_lxml:
       with open(xsil_fname) as xml:
           xsil = objectify.parse(xml).getroot()
       ulong_len = xsil.XSIL.Array[1].Stream.Metalink.get("UnsignedLong")
       precision = xsil.XSIL.Array[1].Stream.Metalink.get("precision")
   else:
       xml = open(xsil_fname).read()
       ulong_len = str(xml2obj.xml2obj(xml).XSIL[0].Array[1].Stream.Metalink.UnsignedLong)
       precision = str(xml2obj.xml2obj(xml).XSIL[0].Array[1].Stream.Metalink.precision)
   ulong_type = {'uint32':'<u4','uint64':'<u8'}[ulong_len]
   float_type = {'single':'<f4','double':'<f8'}[precision]

   with open(indat_fname,'rb') as f:
       xlen = fromfile(f, ulong_type, 1)[0]
       xs   = fromfile(f, float_type, xlen)
       ylen = fromfile(f, ulong_type, 1)[0]
       ys   = fromfile(f, float_type, ylen)
       zlen = fromfile(f, ulong_type, 1)[0]
       zs   = fromfile(f, float_type, zlen)

       rlen1  = fromfile(f, ulong_type, 1)[0]
       reals1 = fromfile(f, float_type, rlen1)
       ilen1  = fromfile(f, ulong_type, 1)[0]
       imags1 = fromfile(f, float_type, ilen1)
       psi1 = (reals1+1j*imags1).astype(np.complex64).reshape(xlen,ylen,zlen)
       del reals1, imags1

       rlen2  = fromfile(f, ulong_type, 1)[0]
       reals2 = fromfile(f, float_type, rlen2)
       ilen2  = fromfile(f, ulong_type, 1)[0]
       imags2 = fromfile(f, float_type, ilen2)
       psi2 = (reals2+1j*imags2).astype(np.complex64).reshape(xlen,ylen,zlen)
       del reals2, imags2

   return psi1, psi2

which sort of works, except for the wrapping - maybe I did something wrong with the template. I'll have another go one day (maybe)
