copied!<p>JavaScript comes with a powerful <code>replace()</code> method for string objects.</p> <p>In general - and basic - terms, it works this way:</p> <pre><code>var myString = yourString.replace([regular expression or simple string], [replacement string]); </code></pre> <p>The first argument to <code>.replace()</code> method is the portion of the original string that you wish to replace. It can be represented by either a plain string object (even literal) or a regular expression.</p> <p>The regular expression is obviously the most powerful way to select a substring.</p> <p>The second argument is the string object (even literal) that you want to provide as a replacement.</p> <p>In your case, the replacement operation should look as follows:</p> <pre><code>xmlData=xmlData.replace(/&/g,"&amp;"); xmlData=xmlData.replace(/>/g,"&gt;"); //this time it should work. </code></pre> <p>Notice the first replacement operation is the ampersand, as if you should try to replace it later you would screw up pre-existing well-quoted entities for sure, just as <code>"&amp;gt;"</code>. </p> <p>In addition, pay attention to the regex 'g' flag, as with it the replacement will take place all throughout your text, not only on the first match. </p> <p>I used regular expressions, but for simple replacements like these also plain strings would be a perfect fit.</p> <p>You can find a complete reference for <code>String.replace()</code> <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/String/replace" rel="nofollow">here</a>.</p>
