   Function: getChildNodeName

       Cycle through the child nodes and find the first instance of the name.

XMLNode.prototype.getChildNodeName = function(nName) {
   for (var i=0; i<this.childNodes.length; i++) {
      var tChild = this.childNodes[i];
      if (tChild.nodeName === nName) {
         return tChild;
   return null;
                    Serve XHTML as application/xhtml+xml to browsers which accept it (and to W3C Validator).

header("Vary: Accept");
if (stristr($_SERVER['HTTP_ACCEPT'], 'application/xhtml+xml') || stristr($_SERVER["HTTP_USER_AGENT"],"W3C_Validator"))
  header('Content-type: application/xhtml+xml');
  echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
  header('Content-type: text/html');
                    A request for this came up on the CF-Talk list recently. Here's what I came up with.
<!--- The list with want to clean up --->
<cfset lst = "a,list,with,a,few,duplicates">
<!--- Use a struct to build a set of the list elements --->
<cfset set = StructNew()>
<cfloop index="elem" list="#lst#">
    <cfset set[elem] = "">
<!--- Convert the set back to a list --->
<cfset lst = StructKeyList(set)>
This sort of this should be familiar to all you perlmongers out there.                
    response.setHeader("Cache-Control", "no-cache");
function loadXMLDoc(url) {
    // branch for native XMLHttpRequest object
    if (window.XMLHttpRequest) {
        req = new XMLHttpRequest();
        //function_name is the function to process request
        req.onreadystatechange = function_name;"GET", url, true);
    // branch for IE/Windows ActiveX version
    } else if (window.ActiveXObject) {
        req = new ActiveXObject("Microsoft.XMLHTTP");
        if (req) {

            //function_name is the function to process request        
            req.onreadystatechange = actualizarLista;
  "GET", url, true);
if (req.readyState == 4) {

	if (req.status == 200) {
            // ...processing statements go here...

            response = req.responseXML;
            results = response.getElementsByTagName(name);

                    Assume you have copied a file across the network using something like this:

scp host:/path/to/file .

Then assume something goes wrong, so the transfer is interrupted. To continue the transfer, do this:

rsync --partial host:/path/to/file .

(Or, rather, always use rsync as above when transferring very large files.)

(Also note: I don't know how frequently rsync flushes its buffer, but don't assume something is wrong just because the file you're downloading doesn't increase in size in the file system. When you interrupt rsync using Ctrl-C, it will flush its buffers.)                

   #`kill -9 #{$$}` # this will successfully kill you
   puts "after kill"
   puts "HA HA!"

always interesting to play with this kind of code.
and discover how much ensure means ENSURE !!!!
