Syntax Error with JSON.Parse method to parse SharePoint List Items

Question

Hi All,
I want to get SharePoint List data and bind that retrived data to the JQuery Grid Control.
For this I used SPServices to get the SharePoint List data in SOAP Envelope. Now I need to parse the soap envelope and store the retrieved items in array to pass it to the Grid Control.
While using the JSON.Parse(resporseText) method, Iam consistenly getting an Syntax Error!
Could anyone help me with this ?
Please find the SOAP Envelope I received from SP List as below:
"<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><GetListItemsResponse xmlns="http://schemas.microsoft.com/sharepoint/soap/"><GetListItemsResult><listitems xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882'

</rs:data>
</listitems></GetListItemsResult></GetListItemsResponse></soap:Body></soap:Envelope>"
Any help on this will be greatly appreciated.
Thanks In Advance.!

Hi,
According to your description, there is an issue when parsing result from the data retrieved using SPServices.
By default, SPServices returns data as XML format, however, the JSON.parse() method “Throws a SyntaxError exception if the string to parse is not valid JSON”:
https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse
To extract the data needed from the response, you can either take the demo below for as a reference:
http://spservices.codeplex.com/wikipage?title=GetListItems
Or use the jQuery.parseXML() function:
http://api.jquery.com/jquery.parsexml/
