DOMDocument: Ignore Duplicate Element IDs
I'm putting some page content (which has been run through Tidy, but doesn't need to be if this is a source of problems) into DOMDocument using DOMDocument::loadHTML.
It's coming up with various errors:
ID x already defined in Entity, line X
Is there any way to make either DOMDocument (or Tidy) ignore or strip out duplicate element IDs, so it will actually create the DOMDocument?
Thanks. :)

A quick search on the subject reveals this (incorrect) bug report:

The last reply states the following:
You're using HTML 4 rules to load an XHTML document. Either use the load() method to parse as XML or the libxml_use_internal_errors() function to ignore the warnings.
I can't be sure if you are encountering this problem for the same reasons, since you did not include a reference to the HTML page being loaded. In any case, using libxml_use_internal_errors() should at least suppress the error.
ID's in HTML documents are generally unique, so the best solution would still be validating your document, if at all possible.
