(MFC) Demonstrate the XML FindNextRecord Method

Imagine we have an XML file as follows:

<CompleteMultipartUpload>
  <Part>
    <PartNumber>1</PartNumber>
    <ETag>abc</ETag>
  </Part>
  <Part>
    <PartNumber>2</PartNumber>
    <ETag>def</ETag>
  </Part>
  <Part>
    <PartNumber>3</PartNumber>
    <ETag>ghi</ETag>
  </Part>
</CompleteMultipartUpload>

We want to find the record where PartNumber = 2. To do so, we simply position ourselves at the first "Part" tag, and then call FindNextRecord. (See below..)

    CkXml *foundRec = xml.FindNextRecord("PartNumber","2");
    if (xml.get_LastMethodSuccess() == true) {
        strOut.append("Found the record where PartNumber = 2.");
        strOut.append("\r\n");
        strOut.append(foundRec->getXml());
        strOut.append("\r\n");

        // Let's examine the ETag for this record...
        strOut.append("ETag for PartNumber 2 = ");
        strOut.append(foundRec->getChildContent("ETag"));
        strOut.append("\r\n");
        delete foundRec;
    }
    else {
        strOut.append("No record exists where PartNumber = 2.");
        strOut.append("\r\n");
    }

    // What if we want to find the record where ETag = "abc"?
    foundRec = xml.FindNextRecord("ETag","abc");
    if (xml.get_LastMethodSuccess() == true) {
        strOut.append("Found the record where ETag = abc");
        strOut.append("\r\n");
        strOut.append(foundRec->getXml());
        strOut.append("\r\n");

        // Let's examine the PartNumber for this record...
        strOut.append("Part number for Etag(abc) = ");
        strOut.append(foundRec->getChildContent("PartNumber"));
        strOut.append("\r\n");
        delete foundRec;
    }
    else {
        strOut.append("No record exists where ETag = abc.");
        strOut.append("\r\n");
    }

    // Go back to the XML root..
    xml.GetRoot2();


    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());

    }
