I am using the following code in angular JS template to open outlook with some fields pre filled.

```
<a href="mailto:{{item.caseOwner}}?subject= Case {{item.caseNumber}}">OWNER</a>

```

where -

```
item.caseOwner = abc@xyz.com;

```

This works fine when `item.caseOwner` is a string. But in some scenarios, it comes wrapped in an HTML tag for the highlighting purpose.

```
item.caseOwner = <span class"highlight">abc@xyz.com<span>;

```

In this case the outlook opens up with HTML tags and it makes no meaning. Is there a way to extract the string inside the `<span></span>` before the user clicks the link ?
