That sounded good so I tried it.  The code now looks like:

def isResultValue(buffer):
    print buffer
    parser = saxexts.make_parser()

    dh = SaxBuilder()

    parser.setDocumentHandler(dh)

    fh = StringIO.StringIO(buffer)
    parser.parseFile(fh)

    doc = dh.document
    print doc.getElementsByTagName("isResultsInfo")

    parser.close()
    fh.close()

and when I run it, I get:

<isResult>
<isResultInfo rows="-1" status="-6"></isResultInfo>
</isResult>

<NodeList []>

Now, looking at the buffer I can see there's a <isResultInfo> node, but it
*never* seems to show up.  It's driving me nuts!!!
