PHP Bug Type: DOM XML related
Bug description: DOM XML tags with empty value generate different xml than
tags with no value
Description:
------------
When a tag created with DOMDocument->createElement() is given *no* value,
its generated output (using DOMDocument->saveXML()) is a shortened
(self-closing) tag, but when it is given an *empty* value such as a blank
string or NULL, it displays as an expanded (opening and closing) tag.
Shouldn't any empty value be treated the same? If anyone really wanted
expanded tags, they could use the already implemented LIBXML_NOEMPTYTAG
option, but there is no equivalent option to ask for shortened tags.
Reproduce code:
---------------
$doc1 = new DOMDocument();
$root1 = $doc1->createElement('root');
$doc1->appendChild($root1);
printf( "doc1: %s\n", $doc1->saveXML() );
$doc2 = new DOMDocument();
$root2 = $doc2->createElement('root', '');
$doc2->appendChild($root2);
printf( "doc2: %s\n", $doc2->saveXML() );
$doc3 = new DOMDocument();
$root3 = $doc3->createElement('root', NULL);
$doc3->appendChild($root3);
printf( "doc3: %s\n", $doc3->saveXML() );
Expected result:
----------------
doc1: <?xml version="1.0"?><root/>
doc2: <?xml version="1.0"?><root/>
doc3: <?xml version="1.0"?><root/>
Actual result:
--------------
doc1: <?xml version="1.0"?><root/>
doc2: <?xml version="1.0"?><root></root>
doc3: <?xml version="1.0"?><root></root>
