ns_tagelement - Find the value of an attribute in an HTML element.
This command takes a string containing an HTML element, tag, and searches it for the specified attribute. If the attribute is found, its value is returned. If the attribute is not found, an empty string is returned. If the attribute's value is surrounded by double quotes, they will be removed.
% set tag {<img height=150 border=0 class="c1 c2" src='me.jpg'>}
<img height=150 border=0 class="c1 c2" src='me.jpg'>
% ns_tagelement $tag id
% ns_tagelement $tag border
150
% ns_tagelement $tag class
c1 c2
% ns_tagelement $tag src
'me.jpg'
Is not removing single quotes surrounding the value a bug?
