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..) C

#include <C_CkXml.h>

void ChilkatSample(void)
    {
    HCkXml xml;
    HCkXml foundRec;

    xml = CkXml_Create();

    CkXml_LoadXmlFile(xml,"qa_data/xml/multipartUpload.xml");

    // Position ourselves at the 1st record.
    CkXml_GetChild2(xml,0);

    foundRec = CkXml_FindNextRecord(xml,"PartNumber","2");
    if (CkXml_getLastMethodSuccess(xml) == TRUE) {
        printf("Found the record where PartNumber = 2.\n");
        printf("%s\n",CkXml_getXml(foundRec));

        // Let's examine the ETag for this record...
        printf("ETag for PartNumber 2 = %s\n",CkXml_getChildContent(foundRec,"ETag"));
        CkXml_Dispose(foundRec);
    }
    else {
        printf("No record exists where PartNumber = 2.\n");
    }

    // What if we want to find the record where ETag = "abc"?
    foundRec = CkXml_FindNextRecord(xml,"ETag","abc");
    if (CkXml_getLastMethodSuccess(xml) == TRUE) {
        printf("Found the record where ETag = abc\n");
        printf("%s\n",CkXml_getXml(foundRec));

        // Let's examine the PartNumber for this record...
        printf("Part number for Etag(abc) = %s\n",CkXml_getChildContent(foundRec,"PartNumber"));
        CkXml_Dispose(foundRec);
    }
    else {
        printf("No record exists where ETag = abc.\n");
    }

    // Go back to the XML root..
    CkXml_GetRoot2(xml);


    CkXml_Dispose(xml);

    }
