[Biopython] NCBIXML: 'generator' objecthas no attribute 'alignments'

[Mic]

My mistake. This is the solution
from Bio.Blast import NCBIXML

with open("test/XA10m_v3.0.aa.snap_vs_uniref90.blastp.xml") as bf:
    blast_records = NCBIXML.parse(bf)

    for blast_record in blast_records:
        for alignment in *blast_record.alignments*:
            for hsp in alignment.hsps:
                if hsp.expect < 0.04:
                    print '****Alignment****'
                    print 'sequence:', alignment.title
                    print 'length:', alignment.length
                    print 'e value:', hsp.expect
                    print hsp.query[0:75] + '...'
                    print hsp.match[0:75] + '...'
                    print hsp.sbjct[0:75] + '...'
