copied!<p>I have an issue where someone isn't properly escaping double quotes in values later to be interpreted as a JSON string. </p> <p>String example:</p> <pre><code>{"description":"This is my 12" pizza I ordered.","value":"1"} </code></pre> <p>When I try to have JSON.parse() handle this it gives an error because of the unescaped double quote (refering to the size in inches) </p> <p>At first, I thought - just do:</p> <pre><code>string.replace(/\"/g,'\"'); </code></pre> <p>but of course this escapes all the valid double-quotes too. So, I'm not an expert on regex, but I looked around for some answers and I think this requires a negative-lookahead?</p> <p>Can someone help construct a regex for finding (for replacement) any sequence of doublequote where the next 2-character sequence following the offending doubleqoute is NOT space-comma? </p> <p>I know this isn't a total universal fix, (getting the person to fix on their end would be), but unfortunately I don't have the luxury of a universal fix.</p> <p>TIA</p> <p>Update - instead of considering the example string (used for illustration only). Is it possible to test for the presence of valid JSON before and after each doublequote - ie to look for any of the following characters ,{[: </p> <p>before and after each doublequote? I guess this is what I was asking - can this be done with lookahead / behind regex?</p>
