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..) Xbase++

LOCAL oXml
LOCAL oFoundRec

oXml := CreateObject("Chilkat.Xml")

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

//  Position ourselves at the 1st record.
oXml:GetChild2(0)

oFoundRec := oXml:FindNextRecord("PartNumber", "2")
IF (oXml:LastMethodSuccess == 1)
    ? "Found the record where PartNumber = 2."
    ? oFoundRec:GetXml()

    //  Let's examine the ETag for this record...
    ? "ETag for PartNumber 2 = " + oFoundRec:GetChildContent("ETag")
    oFoundRec:destroy()
ELSE
    ? "No record exists where PartNumber = 2."
ENDIF

//  What if we want to find the record where ETag = "abc"?
oFoundRec := oXml:FindNextRecord("ETag", "abc")
IF (oXml:LastMethodSuccess == 1)
    ? "Found the record where ETag = abc"
    ? oFoundRec:GetXml()

    //  Let's examine the PartNumber for this record...
    ? "Part number for Etag(abc) = " + oFoundRec:GetChildContent("PartNumber")
    oFoundRec:destroy()
ELSE
    ? "No record exists where ETag = abc."
ENDIF

//  Go back to the XML root..
oXml:GetRoot2()

oXml:destroy()
