[WEB4LIB] MARC -> XML

[Joerg Messer]

Hi Anita,

I've been doing a little hacking using Python, the Zoom PyZ3950 package and
the Amara XML tools. I don't know if my sample code is of any use but I've
included it below. I'm neophyte in this area so I make no claims of this being the prefered way of 
doing things.  If you come up with a better toolset, I'm all ears.

-----------------
from amara import binderytools

conn = zoom.Connection ('z3950.loc.gov', 7090)
conn.databaseName = 'Voyager'
conn.preferredRecordSyntax = 'USMARC'

query = zoom.Query ('CCL', 'ti=law')
results = conn.search (query)
print "Number of results: " + str(len(results))
count = 0;

for result in results:

   count = count + 1

   print "-------------------------------------------"
   print "Record: " + str(count)
   print "-------------------------------------------"

   raw = result.data

   # Convert to MARC
   marcdata = zmarc.MARC(raw)
   # print marcdata

   # Convert to MARCXML
   marcxml  = marcdata.toMARCXML()
   print marcxml

   # Remove non-ascii characters (these cause problems for Amara)
   marcxmlascii = unicode(marcxml, 'ascii', 'ignore').encode('ascii')
   # print marcxmlascii

   doc = binderytools.bind_string(marcxmlascii);

   #print "[" + doc.record.leader.xml_text_content() + "]"


   i = doc.xml_xpath("//datafield[@tag='020']/subfield[@code='a']")
   if len(i)>0:
       isbn = i[0].xml_text_content()
       print "  ISBN: " + isbn

   t = doc.xml_xpath("//datafield[@tag='245']/subfield[@code='a']")
   if len(t)>0:
       title = t[0].xml_text_content()
       print " Title: " + title

   a = doc.xml_xpath("//datafield[@tag='100']/subfield[@code='a']")
   if len(a)>0:
       author = a[0].xml_text_content()
       print "Author: " + author

   print "-------------------------------------------"

conn.close ()
