Using TreatAsArray option in XMLtoJson policy.

[#1]

I am using XmltoJson policy and trying to use TreatAsArray option( to treat an element with single occurrence also as an array), but as i add this option i am getting following error:

Error occurred while validation of bean XML-to-JSON-1.xml. Reason: - Schema validation failed. Cause : unexpected element (uri:"", local:"TreatAsArray"). Expected elements are <{}NamespaceBlockName>,<{}OutputPrefix>,<{}TextAlwaysAsProperty>,<{}NullValue>,<{}OutputSuffix>,<{}AttributeBlockName>,<{}RecognizeBoolean>,<{}AttributePrefix>,<{}TextNodeName>,<{}DefaultNamespaceNodeName>,<{}NamespaceSeparator>,<{}RecognizeNull>,<{}RecognizeNumber>. Line number : 9. Column number : 23. File name : XML-to-JSON-1.xml..

The policy attached and error while saving is :

The error remains same even if i add all the options.

If anyone can help me , it would be very helpful.

Hi @Alok Kumar Singh,

Are you still seeing this error? I created/saved/tested the same basic policy successfully. I can't see any problem with the one you shared. Here's my policy:

<XMLToJSON async="false" continueOnError="false" enabled="true" name="XML-to-JSON">
    <DisplayName>XML to JSON</DisplayName>
    <Properties/>
    <Options>
        <RecognizeNull>true</RecognizeNull>
        <TextNodeName>#text</TextNodeName>
        <AttributePrefix>@</AttributePrefix>
        <TreatAsArray>
            <Path unwrap="true">Base/Item/name</Path>
        </TreatAsArray>
    </Options>
    <OutputVariable>response</OutputVariable>
    <Source>response</Source>
</XMLToJSON>

This is the data I converted:

<Base>
  <Item>
    <name>pod1</name>
    <region>us-east-1</region>
  </Item>
  <Item>
    <name>pod2</name>
    <region>us-west-2</region>
  </Item>
</Base>

And the response -- where the "name" attribute is returned as an array:

{
  "Base": {
    "Item": [{
      "name": ["pod1"],
      "region": "us-east-1"
    }, {
      "name": ["pod2"],
      "region": "us-west-2"
    }]
  }
}<br>

Just to be helpful, I put together a quick illustration of XMLToJSON with TreatAsArray . This is available as a deployable API proxy bundle, with some scripts that help you deploy and run it. All in one github repo.

And, I did a quick screencast on the topic, too. Here 'tis:

Thanks @Dino. Is the option 'TreatAsArray' available in Private Cloud? If Not, Is there any workaround to achieve this in Private Cloud?

@Alok Kumar Singh, are you using Private Cloud? If so, that element isn't available yet.

I didn't realize TreatAsArray is only in Public Cloud at this time. You can of course ignore my answer below if you are using Private Cloud.
