PHP script - adding target="_blank" to links

[booksgo]

Can anyone help with adding <rel="nofollow" target="_blank"> to the code for the 'link' below? I tried adding it in various places, without success. Thanks for any help.

<?php

	echo RSS_Display("http://www.xul.fr/rss.xml", 25);
	?>

$RSS_Content = array();

function RSS_Tags($item, $type)
{
		$y = array();

		$tnl = $tnl->item(0);

Copy all that into a simple notepad program or equivalent.
Use search+replace and replace;
<a href=
with
<a rel='nofollow' target='_blank' href=

It is wrong to suggest using target="". W3 has deprecated this tag and it does not conform to strict w3 standards.

One solutions is to:
<a href="http://forums.x10hosting.com/programming-help/yourpage.html" onclick="window.open('yourpage.html');return false;">

Another alternative that I like to do is change the links using Javascript on the window load. I give each link I want to change a class of "updateLink." Note: if you set more than one class to your links, then you'll have to use a regular expression. Setting the target, using Javascript is perfectly acceptable as W3 specification does not cover DOM control, which JS is.

   for (var e in document.links)
      if (document.links[e].className == "updateLink")
         document.links[e].target="_blank";

The problem with this is that users may have JS turned off. The result will be that the link will open in the same browser window as the page, which is okay because you still have the back button to work with.

It works! Thanks for your help.
Edit:

It's OK for Transitional though, and it works so thats good enough for me

It will work with transitional, but so does align="center" - it doesn't mean you should use it. Transitional should only be used when there is no other choice, but I provided one.

Every page should try to adhere to strict standards as it will not only improve search engine rankings, but the fact will be that transitional will one day be dropped and you'll be forced to reason with strict anyhow.

 

[booksgo]

I know you are right really, but at the moment doing things to Transitional is hard enough for me

all have to start somewhere
