I am working with a javascript function that returns a string of XML. However, within IE I get that string of XML back with escape characters embedded in it e.g. a double quote is a \” " Instead of " Is there an easy way to remove the escaped character sequence items?
Thanks, Derek

Before trying to fix this, you should investigate which other characters are being replaced. For example, when you get a single \ in other browsers do you get \\ in IE?

If the standard C escapes are added, then JSON.parse will convert sequences like \" into ", \\ into \, \n into a line-feed, etc.

'foo\\bar\nbaz"' === JSON.parse('"foo\\\\bar\\nbaz\\""')

JSON.parse is supported natively on most recent browsers, and on IE specifically, back to IE 8. The relevant MSDN page says

Supported in the following document modes: Internet Explorer 8 standards, Internet Explorer 9 standards, Internet Explorer 10 standards. Also supported in Windows Store apps. See Version Information.

Not supported in the following document modes: Quirks, Internet Explorer 6 standards, Internet Explorer 7 standards.

A similar question: Javascript - Replacing the escape character in a string literal explains how to replace a escape character. Maybe you could replace the escape character with empty quotes?

Use JavaScript's replace() method.

jsFiddle:

var string1 = "This is a string with all the \\\" characters escaped";

document.write(string1);    // outputs: This is a string with all the \" characters escaped

document.write("<br />");

string1 = string1.replace("\\", "");

document.write(string1);    // outputs: This is a string with all the " characters escaped
