(VB.NET UWP/WinRT) Demonstrate the XML FindNextRecord Method

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..)

Chilkat for the Universal Windows Platform (UWP)

Dim xml As New Chilkat.Xml

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

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

Dim foundRec As Chilkat.Xml = xml.FindNextRecord("PartNumber","2")
If (xml.LastMethodSuccess = True) Then
    Debug.WriteLine("Found the record where PartNumber = 2.")
    Debug.WriteLine(foundRec.GetXml())

    '  Let's examine the ETag for this record...
    Debug.WriteLine("ETag for PartNumber 2 = " & foundRec.GetChildContent("ETag"))

Else
    Debug.WriteLine("No record exists where PartNumber = 2.")
End If


'  What if we want to find the record where ETag = "abc"?
foundRec = xml.FindNextRecord("ETag","abc")
If (xml.LastMethodSuccess = True) Then
    Debug.WriteLine("Found the record where ETag = abc")
    Debug.WriteLine(foundRec.GetXml())

    '  Let's examine the PartNumber for this record...
    Debug.WriteLine("Part number for Etag(abc) = " & foundRec.GetChildContent("PartNumber"))

Else
    Debug.WriteLine("No record exists where ETag = abc.")
End If


'  Go back to the XML root..
xml.GetRoot2()
