incorrect json output?

[cremol]

I am trying out your extension and this is what i am getting:

xslt:

<xsl:template match="data">
    <response>
        <xsl:apply-templates select="entries/entry" />
    </response>
</xsl:template>

<xsl:template match="entry">
    <firstname>John</firstname>
    <lastname>Doe</lastname>
</xsl:template>

xml output:

<response>
    <firstname>John</firstname>
    <lastname>Doe</lastname>
    <firstname>John</firstname>
    <lastname>Doe</lastname>
    <firstname>John</firstname>
    <lastname>Doe</lastname>
</response>

json output:

{
    "response":
        {
            "firstname": [
                "John",
                "John",
                "John"
            ],
            "lastname": [
                "Doe",
                "Doe",
                "Doe"
            ]
        }
}

expected json output:

{
    "response":
        {
            "firstname": "John",
            "lastname": "Doe"
        },
        {
            "firstname": "John",
            "lastname": "Doe"
        },
        {
            "firstname": "John",
            "lastname": "Doe"
        }
}

Looks like the json output is parsed incorrect?
