Given a string like: 

</gd:organization><gd:email rel='http://schemas.google.com/g/2005#other' address='[email protected]'/><gd:email rel='http://schemas.google.com/g/2005#other' address='[email protected]' primary='true'/><gd:phoneNumber rel='http://schemas.google.com/g/2005#work'>011 360 51 60</gd:phoneNumber>

I need to remove from the string:

<gd:email rel='http://schemas.google.com/g/2005#other' address='[email protected]'/>

- based on a match to: [email protected].

It has to be done in basic JavaScript and I can't import any special parsing tools. I can't seem to find a combination that does not error out.

Thank you!

Nowhere near enough information - you're asking for a general RegEx but provide only one example input/output. Tell us the characteristics of what it is you need to remove. –  Madbreaks Feb 2 '13 at 0:18
 
I get these xml strings that contain contact information from Google and need to remove certain elements containing a certain email address. –  James Ferreira Feb 2 '13 at 0:20
 
Sorry I had not added the full code. –  James Ferreira Feb 2 '13 at 0:25
 
This doesn't look like valid XML (starts with a close tag), if it was you could use DOMParser. RegExp isn't designed to parse stuff like this. –  Paul S. Feb 2 '13 at 0:27
 
If only I could but I need to do it in Google Apps Script which means no DOMParser and there is no built in methods to handle XML. Yes I only posted part of the string. –  James Ferreira Feb 2 '13 at 0:30

If this must be done in RegExp, you could attempt something like the following only if you know that all <gd:email> parts will have an address attribute, quotes are ' and end /> without address=' or /> appearing inside any values on those attributes.

"</gd:organization><gd:email rel='http://schemas.google.com/g/2005#other' address='[email protected]'/><gd:email rel='http://schemas.google.com/g/2005#other' address='[email protected]' primary='true'/><gd:phoneNumber rel='http://schemas.google.com/g/2005#work'>011 360 51 60</gd:phoneNumber>"
.replace(
    /<gd:email .*?address='([^']*)'.*?\/>/g, // match email node
    function (a, b) { // replacement logic
        if (b === '[email protected]') return '';
        return a;
    }
);

As I said in my comment, the best way to achieve this would actually be with DOMParser which is a native JavaScript XML parser, but the string you have given us is not valid XML as it begins with a close tag.

This is simple enough, do tell if you need any changes:

var inputString = "</gd:organization><gd:email rel='http://schemas.google.com/g/2005#other' address='[email protected]'/><gd:email rel='http://schemas.google.com/g/2005#other' address='[email protected]' primary='true'/><gd:phoneNumber rel='http://schemas.google.com/g/2005#work'>011 360 51 60</gd:phoneNumber>";
var outputString = inputString.split("[email protected]")[1].substring(3);
alert(outputString);

I've posted a JSFiddle for it.

I think the email address is an unknown, and it's precisely that piece of info the OP wants to extract... –  Elias Van Ootegem Feb 2 '13 at 0:42
 
@Elias Van Ootegem - Gotcha, but I read it like my example works. 'I need to remove from the string...' and 'Based on a match to: [email protected]'. I'm not a mind reader, though ;) –  TildalWave Feb 2 '13 at 0:44
