Problems trying to parse html string using DOMParser
here is a snippet:
html = "<!doctype html>"; html += "<html>"; html += "<head><title>test</title></head>"; html += "<body><p>test</p></body>"; html += "</html>"; parser = new DOMParser(); dom = parser.parseFromString (html, "text/html"); here an error occurs when trying to execute the following lines:
Error: component return code: 0x80004001 (NS_ERROR_NOT_IMPLEMENTED) [nsIDOMParser.parseFromString]
I am trying to figure out what is happening, but the code seems to be correct, and I searched on the Internet, I came here without any hints.
Have you encountered this error before? if so, where is the error hiding?

You must use the DomParser function described in Accessing DOMParser JavaScript innerHTML and other properties
I created a fiddle for you http://jsfiddle.net/CSAnZ/
