I really think you're making a mistake. If you don't check the user's
input what are you supposed to do when they make a mistake? Are you
going to output the error from the parser saying: 'Invalid document'
--> not very helpful.
But if you must:
Don't bother with a file, just use serialize() and write it to a
string, and then create a new DOMParser and use the MemBufInputSource
class to turn the string into an input source. See
t/MemBufInputSource.t for an example.
