Operating system: Windows/Linux
PHP version: 5.1.2
PHP Bug Type: DOM XML related
Bug description: Inappropriate "unterminated entity reference" in
DOMElement->setAttribute
Description:
------------
While it is not specifically mentioned in the documentation,
DOMElement->setAttribute automatically escapes XML special characters in
the value parameter. Yet, as of PHP 5.1.2 it will throw an "unterminated
entity reference" warning if the supplied value contains an ampersand -
even if it is escaped.
As well as fixing the actual bug, the documentation needs to clarify
*exactly* how special characters in the inputs to this and other DOM
functions are treated. If you are going to silently escape input text, you
need to tell people so that they don't end up with stuff being
double-escaped.
Reproduce code:
---------------
$element->setAttribute ("anattr", "jack & jill") ;
$element->setAttribute ("anattr", "jack & jill") ;
Expected result:
----------------
No warnings should be thrown.
Actual result:
--------------
BOTH calls to setAttribute throw an "unterminated entity reference"
warning.
