.SVG version problems 6.6.0

(@alexim13)

After updating the module to version 6.6.0 the code in the “Home link template” section does not work

The module removes the code and remains

<a property="item" typeof="WebPage" title="Перейти к %title%." href="%link%" class="%type%" bcn-aria-current>

What version of Breadcrumb NavXT did you upgrade from? I ask as this would have been a problem for all modern versions of Breadcrumb NavXT (since 4.3.0 which was released 7 years ago).

You will need to add the SVG tags and attributes to the allowed HTML tags for the breadcrumb templates. The following article covers how to use the bcn_allowed_html filter to add a tag and attributes to the allowed HTML tag list for breadcrumb templates: https://mtekk.us/archives/guides/how-to-add-li-and-other-tags-to-breadcrumb-templates/

Updated from version 6.5.0. Thanks, it worked.

To file breadcrumb-navxt.php after the line $allowed_html = array( add:
```
					'svg' => array(
						'width' => true,
						'height' => true,
						'viewbox' => true,
						'version' => true,
						'xmlns' => true,
						'xmlns:xlink' => true
					),
					'g' => array(
						'stroke' => true,
						'stroke-width' => true,
						'fill' => true,
						'fill-rule' => true,
						'transform' => true
					),
					'path' => array(
						'fill' => true,
						'd' => true,
						'fill-rule' => true
					),
					'polygon' => array(
						'points' => true
					),
```

Can you somehow remove the last separator?

Link template to … (non-clickable) a space is specified to hide the page title.

Modifying breadcrumb-navxt.php is absolutely the wrong thing to do. You need to follow the article I linked and create a site specific plugin that contains a function that hooks into the bcn_allowed_html filter. Otherwise, every time you update Breadcrumb NavXT you will experience this issue.

As for removing the current item, use the remove current item extension: https://github.com/mtekk/Breadcrumb-NavXT-Extensions/blob/master/breadcrumb_navxt_remove_curitm.php This will work much better than using a space in the breacrumb templates.

In the file functions.php added and the tag began to work. How do I add the rest of the tags to the filter (<g>, <path>, <polygon>)?

Can you write the code below?
```
function my_bcn_allowed_html($allowed_html)
    {
	$allowed_html ['svg'] = array(
		'width' => true,
		'height' => true,
		'viewbox' => true,
		'version' => true,
		'xmlns' => true,
		'xmlns:xlink' => true
	);
	return $allowed_html;
	}
add_filter('bcn_allowed_html', 'my_bcn_allowed_html');
```

The $allowed_html variable is an array, each key is for an HTML tag. So, you can use any method you like to add more keys. A simple way is to add more $allowed_html['KEY'] = array(); assignments.

For example, the following should do what you want:
```
function my_bcn_allowed_html($allowed_html)
{
	$allowed_html['svg'] = array(
		'width' => true,
		'height' => true,
		'viewbox' => true,
		'version' => true,
		'xmlns' => true,
		'xmlns:xlink' => true
	);
	$allowed_html['g'] = array(
		'stroke' => true,
		'stroke-width' => true,
		'fill' => true,
		'fill-rule' => true,
		'transform' => true
	);
	$allowed_html['path'] = array(
		'fill' => true,
		'd' => true,
		'fill-rule' => true
	);
	$allowed_html['polygon'] = array(
		'points' => true
	);
	return $allowed_html;
}
add_filter('bcn_allowed_html', 'my_bcn_allowed_html');
```
