Mustache.php rendering multi-dimensional data

I'm utilizing Mustache to template some XML responses for an API. I was wondering how I could use the XML template below to render data from this array? The data is not rendering at all when using this code:

$result = $m->render($template, $r);             
echo $result;

Here is JSON converted data:

[
    {
        "UUID": "655482ab-38ee-433f-b310-1f6f227113b9",
        "RefUUID": "92a8ecf6-8eb6-4d1e-b88d-59b50c3b0cc9",
        "company":"UAR",
        "itemname":"DOOR ",
        "daysinstock":"41",
        "condition":"A",
        "stocknumber":"F0049356",
        "ic":"120-00409AL",
        "price":"750.00",
        "quantity":"1",
        "location":"U3020",
        "comments": "comment for #0"
    },
    {
        "UUID": "655482ab-38ee-433f-b310-1f6f227113b9",
        "RefUUID": "92a8ecf6-8eb6-4d1e-b88d-59b50c3b0cc9",
        "company":"UAR",
        "itemname":"DOOR ",
        "daysinstock":"68",
        "condition":"C",
        "stocknumber":"F0048586",
        "ic":"120-00409AL",
        "price":"750.00",
        "quantity":"1",
        "location":"KEEP"
        "comments": "comment for #1"
    },
    {
        "UUID": "655482ab-38ee-433f-b310-1f6f227113b9",
        "RefUUID": "92a8ecf6-8eb6-4d1e-b88d-59b50c3b0cc9",
        "company":"UAR",
        "itemname":"DOOR ",
        "daysinstock":"280",
        "condition":"B",
        "stocknumber":"171013",
        "ic":"120-00409AL",
        "price":"750.00",
        "quantity":"1",
        "location":"YCR4"
        "comments": "comment for #2"
    }
]

XML template trying to render

$template = '<SupplierResponse>
    <QuotedPartList>
        {{#parts}}
        <QuotedPart>
            <BMSObject>
                <UUID>{{UUID}}</UUID>
                <RefUUID>{{RefUUID}}</RefUUID>

            <PartNumInfo>

            </PartNumInfo>
            <PartNumInfo>

                <PartLocation>{{location}}</PartLocation>
                <PartStore>{{company}}</PartStore>

            </Availability>
            <LineNoteInfo>
                <LineNoteMemo>{{comments}}</LineNoteMemo>
            </LineNoteInfo>
        </QuotedPart>
        {{/parts}}
    </QuotedPartList>
</SupplierResponse>';

Finally got it fixed. The data was not formatted correctly:

    );

Code:

$result = $m->render($template, $r); // Used same template as in my original post.
