Replacing parts of source

Copy linkTweet thisAlerts:
May 29.2005

Hi I want to replace some of the HTML code of the current document with Javascript (Greasemonkey in Firefox). The problem is, that it is not just one tag.

Here is the source:

[code]Cheaterhossie</a></b><br /><br />
<img src=’./avatare/leet.gif’ alt=’Leet’ border=0 />[/code]

Now I want to replace that “leet.gif” with another image, but [u]only[/u] when the username is indeed “Cheaterhossie” like above. Also mind that newline and spaces in the source.

My basic approach

[code]var oldbody = document.body.innerHTML;
var newbody = oldbody.replace(“/xxx/”, “xxx”);
window.addEventListener(
‘load’,
function() { document.body.innerHTML = newbody; },
true);[/code]

didn’t work.

Can anybody help? ?

@CharlesMay 29.2005 — What you want to do is pretty easy, but I need a little more mark up. If you had &lt;div&gt;&lt;a&gt;Cheaterhossie&lt;/a&gt;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;
&lt;img src='./avatare/leet.gif' alt='Leet' border=0 /&gt;&lt;/div&gt;Then you might use (function () {
var e, i = 0;
while (e = document.getElementsByTagName ('img')[i++]) {if (/leet.gif$/.test (e.src) &amp;&amp; e.parentNode.getElementsByTagName ('a')[0].firstChild.data == 'Cheaterhossie') e.src = 'other.png'}
})()

@HossieauthorMay 29.2005 — Yeah I can't edit the page, it's not mine.

Here is the rest of the source:

&lt;b&gt;&lt;a href='javascript:void(0);' onClick='openProfile("58350","here_is_the_current_random_sessionid")' class='onblue'&gt;Cheaterhossie&lt;/a&gt;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;
&lt;img src='./avatare/leet.gif' alt='Leet' border=0 /&gt;

This is embedded in a td...

@CharlesMay 29.2005 — That's still not quite enough, but you should be able to use or adapt what I've posted above.

@HossieauthorMay 29.2005 — &lt;table border=0 cellpadding=3 cellspacing=0 width='100%' height='100%'&gt;
&lt;tr&gt;&lt;td align='left' vAlign='top'&gt;
&lt;a name='reply_ID_goes_here'&gt;&lt;/a&gt;&lt;font color='#EFEFEF'&gt;
&lt;b&gt;&lt;a href='javascript:void(0);' onClick='openProfile("58350","_randon_session_id_here")' class='onblue'&gt;Cheaterhossie&lt;/a&gt;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;
&lt;img src='./avatare/leet.gif' alt='Leet' border=0 /&gt;
&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

I hope thats enough of the code ?
