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..) Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const xml = try chilkat.Xml.init();
    defer xml.deinit();

    xml.loadXmlFile("qa_data/xml/multipartUpload.xml") catch {};

    // Position ourselves at the 1st record.
    xml.getChild2(0) catch {};

    var found_rec: chilkat.Xml = try xml.findNextRecord("PartNumber", "2");
    defer found_rec.deinit();
    if (xml.getLastMethodSuccess()) {
        std.debug.print("Found the record where PartNumber = 2.\n", .{});
        std.debug.print("{s}\n", .{try found_rec.getXml(alloc)});

        // Let's examine the ETag for this record...
        std.debug.print("ETag for PartNumber 2 = {s}\n", .{try found_rec.getChildContent(alloc, "ETag")});
    } else {
        std.debug.print("No record exists where PartNumber = 2.\n", .{});
    }

    // What if we want to find the record where ETag = "abc"?
    {
        const next = try xml.findNextRecord("ETag", "abc");
        found_rec.deinit();
        found_rec = next;
    }
    if (xml.getLastMethodSuccess()) {
        std.debug.print("Found the record where ETag = abc\n", .{});
        std.debug.print("{s}\n", .{try found_rec.getXml(alloc)});

        // Let's examine the PartNumber for this record...
        std.debug.print("Part number for Etag(abc) = {s}\n", .{try found_rec.getChildContent(alloc, "PartNumber")});
    } else {
        std.debug.print("No record exists where ETag = abc.\n", .{});
    }

    // Go back to the XML root..
    xml.getRoot2();
}
