Demonstrate the XML FindNextRecord Method

See more XML Examples

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..) Unicode C++

#include <CkXmlW.h>

void ChilkatSample(void)
    {
    CkXmlW xml;

    xml.LoadXmlFile(L"qa_data/xml/multipartUpload.xml");

    // Position ourselves at the 1st record.
    xml.GetChild2(0);

    CkXmlW *foundRec = xml.FindNextRecord(L"PartNumber",L"2");
    if (xml.get_LastMethodSuccess() == true) {
        wprintf(L"Found the record where PartNumber = 2.\n");
        wprintf(L"%s\n",foundRec->getXml());

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

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

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

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