help with php bug #47532

Hi, I wont fix this bug: http://bugs.php.net/bug.php?id=47532, but have some questions. Can you help me? There is the test case: http://pastebin.org/91030 First, I careful that when we fix this bug, we have broken BC, because now when we write $attr->value = "foo&bar"; - value has been escaped and in var_dump($attr->value) we got "foo&bar". For fix this bug we must remove escaping. This is right? Second, for remove escaping I think we need use this patch: Index: attr.c =================================================================== --- attr.c (revision 294790) +++ attr.c (working copy) @@ -193,7 +193,7 @@ convert_to_string(newval); } - xmlNodeSetContentLen((xmlNodePtr) attrp, Z_STRVAL_P(newval), Z_STRLEN_P(newval) + 1); + xmlNodeAddContentLen((xmlNodePtr) attrp, Z_STRVAL_P(newval), Z_STRVAL_P(newval) + 1); if (newval == &value_copy) { zval_dtor(newval); This patch fix this cases: $attr = new DOMAttr('test', 'foo&bar'); var_dump($attr->value); $attr->value = "foo&bar"; var_dump($attr->value); but in this case we got empty value: $doc = new DOMDocument; $attr = $doc->createAttribute("foo"); $attr->value = "foo&bar"; var_dump($attr->value); Can you explain why? in first two cases wiil be call xmlNewProp libxml2 function, in last case - xmlNewDocProp. Both this functions return same variable type. -- -- Best regards
