(Unicode C) Demonstrate the XML FindNextRecord MethodImagine 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..)
#include <C_CkXmlW.h> void ChilkatSample(void) { HCkXmlW xml; HCkXmlW foundRec; xml = CkXmlW_Create(); CkXmlW_LoadXmlFile(xml,L"qa_data/xml/multipartUpload.xml"); // Position ourselves at the 1st record. CkXmlW_GetChild2(xml,0); foundRec = CkXmlW_FindNextRecord(xml,L"PartNumber",L"2"); if (CkXmlW_getLastMethodSuccess(xml) == TRUE) { wprintf(L"Found the record where PartNumber = 2.\n"); wprintf(L"%s\n",CkXmlW_getXml(foundRec)); // Let's examine the ETag for this record... wprintf(L"ETag for PartNumber 2 = %s\n",CkXmlW_getChildContent(foundRec,L"ETag")); CkXmlW_Dispose(foundRec); } else { wprintf(L"No record exists where PartNumber = 2.\n"); } // What if we want to find the record where ETag = "abc"? foundRec = CkXmlW_FindNextRecord(xml,L"ETag",L"abc"); if (CkXmlW_getLastMethodSuccess(xml) == TRUE) { wprintf(L"Found the record where ETag = abc\n"); wprintf(L"%s\n",CkXmlW_getXml(foundRec)); // Let's examine the PartNumber for this record... wprintf(L"Part number for Etag(abc) = %s\n",CkXmlW_getChildContent(foundRec,L"PartNumber")); CkXmlW_Dispose(foundRec); } else { wprintf(L"No record exists where ETag = abc.\n"); } // Go back to the XML root.. CkXmlW_GetRoot2(xml); CkXmlW_Dispose(xml); } |
