Can scripts be inserted with innerHTML?

Here is a method that recursively replaces all scripts with executable ones:

function nodeScriptReplace(node) {
        if ( nodeScriptIs(node) === true ) {
                node.parentNode.replaceChild( nodeScriptClone(node) , node );
        }
        else {
                var i = -1, children = node.childNodes;
                while ( ++i < children.length ) {
                      nodeScriptReplace( children[i] );
                }
        }

        return node;
}
function nodeScriptClone(node){
        var script  = document.createElement("script");
        script.text = node.innerHTML;

        var i = -1, attrs = node.attributes, attr;
        while ( ++i < attrs.length ) {                                    
              script.setAttribute( (attr = attrs[i]).name, attr.value );
        }
        return script;
}

function nodeScriptIs(node) {
        return node.tagName === 'SCRIPT';
}

Example call:

nodeScriptReplace(document.getElementsByTagName("body")[0]);
