Hi SaravudhS,
From the error, it seems the response HTML content cause the DOMParser throw an error. For test, you can try loading the target page's html content in a .NET console app (and use either XDocument or some other html parsing library) to see if the response
html content is well-formed xml or if it is valid html.
For html data parsing in windows store javascript, you can also try using jquery api to simplify the html content loading and querying. But you need to convert the jquery object into raw HTML DOM objects before you will add them to the Windows Store UI page's
DOM structure.
Please remember to mark the replies as answers if they help and unmark them if they provide no help.
