how to parse xml from an http-triggered logic app?

Question

How do I extract the content of my request that's been received inside of the logic app?

I've got a regular http-triggered logic app, like so:

I'm sending it a POST request through postman like so:

{
    "$content-type": "application/octet-stream",
    "$content": "<?xml version=\"1.0\" encoding=\"UTF-8\"?><cases><file-path>yes</file-path></cases>"
}

I'm attempting to extract the $content payload:

"@{string(xml(string(triggerBody()?['content'])))}"

The issue I am getting is:

How do I extract the content of my request that's been received inside of the logic app?

Here's the entire initialize variable step:

    "Initialize_variable": {
        "inputs": {
            "variables": [
                {
                    "name": "contentOfRequest",
                    "type": "String",
                    "value": "@{string(xml(string(triggerBody()?['content'])))}"
                }
            ]
        },
        "runAfter": {},
        "type": "InitializeVariable"
    }

Cause the request body is string, it doesn't support select property. so you need parse it Json format firstly, then you will be able to select $content.

About how to get the Json Schema, just click the Use sample payload to generate schema in the Parse Json action and paste your Json data, then click the done.

And then extract the $content value with body('Parse_JSON')?['$content'], in this way you will get the content value.
