Executing [removed] elements inserted with [removed]

Question

I\'ve got a script that inserts some content into an element using innerHTML.

The content could for example be:

Answer 1

Extending off of Larry's. I made it recursively search the entire block and children nodes.
The script now will also call external scripts that are specified with src parameter. Scripts are appended to the head instead of inserted and placed in the order they are found. So specifically order scripts are preserved. And each script is executed synchronously similar to how the browser handles the initial DOM loading. So if you have a script block that calls jQuery from a CDN and than the next script node uses jQuery... No prob! Oh and I tagged the appended scripts with a serialized id based off of what you set in the tag parameter so you can find what was added by this script.

exec_body_scripts: function(body_el, tag) {
    // Finds and executes scripts in a newly added element's body.
    // Needed since innerHTML does not run scripts.
    //
    // Argument body_el is an element in the dom.

    function nodeName(elem, name) {
        return elem.nodeName && elem.nodeName.toUpperCase() ===
              name.toUpperCase();
    };

    function evalScript(elem, id, callback) {
        var data = (elem.text || elem.textContent || elem.innerHTML || "" ),
            head = document.getElementsByTagName("head")[0] ||
                      document.documentElement;

        var script = document.createElement("script");
        script.type = "text/javascript";
        if (id != '') {
            script.setAttribute('id', id);
        }

        if (elem.src != '') {
            script.src = elem.src;
            head.appendChild(script);
            // Then bind the event to the callback function.
            // There are several events for cross browser compatibility.
            script.onreadystatechange = callback;
            script.onload = callback;
        } else {
            try {
                // doesn't work on ie...
                script.appendChild(document.createTextNode(data));      
            } catch(e) {
                // IE has funky script nodes
                script.text = data;
            }
            head.appendChild(script);
            callback();
        }
    };

    function walk_children(node) {
        var scripts = [],
          script,
          children_nodes = node.childNodes,
          child,
          i;

        if (children_nodes === undefined) return;

        for (i = 0; i
