escape HTML tags in phpTal

<!-- ... -->

<!-- You have to use ${structure expresssion} syntax to escape HTML tags. 
     The use of "tal:define" (to handle the case when no string is defined in the array) is important 
     because we can't combine the two PHPTALES "structure" and "string" in the same expression. -->
<div tal:define="myVarWithTags string:a br tag<br/>for example">
    ${structure myArray/ofString | myVarWithTags}
</div>
