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..) Node.js

function chilkatExample() {

    var xml = new chilkat.Xml();

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

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

    // foundRec: Xml
    var foundRec = xml.FindNextRecord("PartNumber","2");
    if (xml.LastMethodSuccess == true) {
        console.log("Found the record where PartNumber = 2.");
        console.log(foundRec.GetXml());

        // Let's examine the ETag for this record...
        console.log("ETag for PartNumber 2 = " + foundRec.GetChildContent("ETag"));

    }
    else {
        console.log("No record exists where PartNumber = 2.");
    }

    // What if we want to find the record where ETag = "abc"?
    foundRec = xml.FindNextRecord("ETag","abc");
    if (xml.LastMethodSuccess == true) {
        console.log("Found the record where ETag = abc");
        console.log(foundRec.GetXml());

        // Let's examine the PartNumber for this record...
        console.log("Part number for Etag(abc) = " + foundRec.GetChildContent("PartNumber"));

    }
    else {
        console.log("No record exists where ETag = abc.");
    }

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

}
