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..) Rust

let xml = chilkat::Xml::new();

let _ = xml.load_xml_file("qa_data/xml/multipartUpload.xml");

// Position ourselves at the 1st record.
let _ = xml.get_child2(0);

let mut found_rec = xml.find_next_record("PartNumber", "2").unwrap();
if xml.last_method_success() {
    println!("Found the record where PartNumber = 2.");
    println!("{}", found_rec.get_xml().unwrap_or_default());

    // Let's examine the ETag for this record...
    println!("ETag for PartNumber 2 = {}", found_rec.get_child_content("ETag").unwrap_or_default());

} else {
    println!("No record exists where PartNumber = 2.");
}

// What if we want to find the record where ETag = "abc"?
found_rec = xml.find_next_record("ETag", "abc").unwrap();
if xml.last_method_success() {
    println!("Found the record where ETag = abc");
    println!("{}", found_rec.get_xml().unwrap_or_default());

    // Let's examine the PartNumber for this record...
    println!("Part number for Etag(abc) = {}", found_rec.get_child_content("PartNumber").unwrap_or_default());

} else {
    println!("No record exists where ETag = abc.");
}

// Go back to the XML root..
xml.get_root2();
