Python example for scripting the RCSB-PDB RESTful web services
This advanced search finds all PDBs that have been resolved using Solid State NMR.
For more information on the RESTful web services see here.
import urllib2
url = 'http://www.rcsb.org/pdb/rest/search'
queryText = """
<?xml version="1.0" encoding="UTF-8"?>

<description>Experimental Method Search : Experimental Method=SOLID-STATE NMR</description>
<mvStructure.expMethod.value>SOLID-STATE NMR</mvStructure.expMethod.value>
</orgPdbQuery>
"""
print "query:\n", queryText
print "querying PDB...\n"
req = urllib2.Request(url, data=queryText)
f = urllib2.urlopen(req)
result = f.read()
if result:
print "Found number of PDB entries:", result.count('\n')
else:
print "Failed to retrieve results"
Thanks to Jurgen F. Doreleijers for suggesting this example.
