Add taxonomy combinations to YOAST sitemap

Question

Used rewrite rules to achieve the current url setup but I need these combinations also added to the sitemap. 'collection' is just a product attribute with the taxonomy of pa_collection

Current URL Setup

https://*****.com/collection/%COLLECTION-TERM%/product-tag/%PRODUCT-TAG-TERM%

	}

This is the section is where I need to combine the taxonomies. So far I have all the terms for both taxonomies on the same page but I need to have them combined to create all the possible combinations.

$practitioner_terms = get_terms( 'pa_collection', 'orderby=count&hide_empty=0' );
$practitioner_termss = get_terms( 'product_tag', 'orderby=count&hide_empty=0' ); 

if( !empty( $practitioner_terms ) ){
    $pri = 1;
    $chf = 'weekly';
    foreach ($practitioner_terms as $key => $term ){
        $url = array();
         $url['loc'] =site_url().'/collection/'.$term>slug.'/product-tag/';

            $url['pri'] = $pri;
            $url['mod'] = $mod;
            $url['chf'] = $chf;
            $output .= $wpseo_sitemaps->sitemap_url( $url );
    }
    foreach ($practitioner_termss as $key => $term ){
        $url = array();
        $url['loc'] = site_url().'/product-tag/'.$term->slug;
            $url['pri'] = $pri;
            $url['mod'] = $mod;
            $url['chf'] = $chf;
            $output .= $wpseo_sitemaps->sitemap_url( $url );
    }
}

想出一个可行的解决方案，可能对其他人有用...

$practitioner_terms = get_terms( 'pa_collection', 'orderby=count&hide_empty=0' );
$practitioner_termss = get_terms( 'product_tag', 'orderby=count&hide_empty=0' );

if( !empty( $practitioner_terms ) ){
    $pri = 1;
    $chf = 'weekly';
    foreach ($practitioner_terms as $key => $term ){
        foreach ($practitioner_termss as $key => $terms ){
        $url = array();
        $url['loc'] = site_url().'/collection/'.$term->slug.'/product-tag/'.$terms->slug;
            $url['pri'] = $pri;
            $url['mod'] = $mod;
            $url['chf'] = $chf;
            $output .= $wpseo_sitemaps->sitemap_url( $url );

    }

    }
