Description

oneListGroup option seems to have no effect and produces cdata items errors

Input

Code

configuration

const builder = new XMLBuilder({
     processEntities: true,
    ignoreAttributes : false,
    attributeNamePrefix: '$',
    textNodeName: '_content',
    cdataPropName: '_cdata',
    suppressBooleanAttributes: false,
    oneListGroup: true
  });

json data

{
    "table": {
        "caption": "Table caption",
        "row": [
            [
                {
                    "cell": "cell 1"
                },
                {
                    "cell": "cell 2"
                },
                {
                    "cell": "cell 3"
                }
            ],
            [
                {
                    "cell": "cell 3"
                },
                {
                    "cell": "cell 4"
                },
                {
                    "cell": "cell 5"
                }
            ]
        ]
    }
}

Output

<?xml version="1.0"?>
<table>
  <caption>Table caption</caption>
  <row>
    <0>
      <cell>cell 1</cell>
    </0>
    <1>
      <cell>cell 2</cell>
    </1>
    <2>
      <cell>cell 3</cell>
    </2>
  </row>
  <row>
    <0>
      <cell>cell 3</cell>
    </0>
    <1>
      <cell>cell 4</cell>
    </1>
    <2>
      <cell>cell 5</cell>
    </2>
  </row>
</table>

In addition, adding the oneListGroup option, also cdata processing fails:

<descr>
  <_cdata>&lt;p&gt;some text&lt;/p&gt;</_cdata>
</descr>

expected output

<table>
  <caption>Composizione del MOL</caption>
  <row>
    <cell>cell 1</cell>
    <cell>cell 2</cell>
    <cell>cell 3</cell>
  </row>
  <row>
    <cell>cell 4</cell>
    <cell>cell 5</cell>
    <cell>cell 6</cell>
  </row>
</table>

Have you tested it with preserveOrder option? Because your JSON data look like in that format.

[massimo-cassandro]

tested, same result
Thanks

[amitguptagwl]

@massimo-cassandro please share the code with config you're using to parse from XML to JSON and back to XML.

[massimo-cassandro]

Hi, i can't add the real code now. But it was quite the same i've inserted when opening the issue

[amitguptagwl]

You need not to insert the real code. What matters is the config you are using for for transformation. Share that part of the code only. The original code you shared misses the configuration I asked in last comment. But you have mentioned that you have tried with new configuration too. Hence, I need to know the right cod config you're using for both transformation.

[massimo-cassandro]

Maybe I missed something, but I mean this is the configuration, isnt'it?

const builder = new XMLBuilder({
     processEntities: true,
    ignoreAttributes : false,
    attributeNamePrefix: '$',
    textNodeName: '_content',
    cdataPropName: '_cdata',
    suppressBooleanAttributes: false,
    oneListGroup: true
  });

I've also tried with preserveOrder: true, as you asked, but I got the same result. Thanks

[amitguptagwl]

Your input JSON is not as per the expected format. You must either generate with the FXP parser or should build as below format.

When preserveOrder is true

When preserveOrder is false

When oneListGroup is also false

<table>
  <caption>Composizione del MOL</caption>
  <row>
    <cell>cell 1</cell>
    <cell>cell 2</cell>
    <cell>cell 3</cell>
  </row>
  <row>
    <cell>cell 4</cell>
    <cell>cell 5</cell>
    <cell>cell 6</cell>
  </row>
</table>

I hope this is what you were expecting.
