Error: Client parser breaks when first element has attributes

[remarkablemark]

When the client parser parses an HTML string where the first element has attribute(s), this causes the regex to match an improper tag name and throw an error on this line.

Example:

// works
HTMLReactParser('<p>foo</p>');

// breaks
HTMLReactParser('<p id="bar">foo</p>');

Error thrown:

TypeError: Cannot read property 'parentNode' of undefined
