Using your sample code, how would you modify an existing value? Like changing the price from 42.50 to 50

<catalog>
    <product description="Cardigan Sweater" product_image="cardigan.jpg" >
        <catalog_item gender="Men's" >
            <item_number>QWZ5671</item_number>
            <price>39.95</price>
            <size description="Medium" >
                <color_swatch image="red_cardigan.jpg" >Red</color_swatch>
                <color_swatch image="burgundy_cardigan.jpg" >Burgundy</color_swatch>
            </size>
            <size description="Large" >
                <color_swatch image="red_cardigan.jpg" >Red</color_swatch>
                <color_swatch image="burgundy_cardigan.jpg" >Burgundy</color_swatch>
            </size>
        </catalog_item>
        <catalog_item gender="Women's" >
            <item_number>RRX9856</item_number>

For me it worked if I use something like the following:

let color0 = xml.product.catalog_item.price.xml?.value = "50"
