PHP Bug Type: DOM XML related
Bug description: invalid entities handling into set_attribute() and set_content()
Please take a look at following example:
<?php
$xml = domxml_open_mem('<'.'?xml version="1.0"?'.'><root/>');
$root = $xml->root();
$value = $root->set_attribute('a','a&b');
$value = $root->set_content('a&b');
echo $xml->dump_mem();
?>
It produces following results:
<?xml version="1.0"?>
<root a="a&amp;b">a&b</root>
As you may see - & entity is treated as literals when it is being set
as attribute value while same entity is treated as entity reference being
set as node value.
I have checked PHP's DOMXML extension source, libxml2 sources and discuss
about this behaviour with Daniel Viellard (libxml2 maintainer) and with
some other people on public XML-related forums and here is some
information about this issue:
1. Such behaviour is not a libxml2 bug, it is expected behaviour. Moreover
it is more correct from a point of specifications.
2. There should be a way to access Attr DOM object as specified into DOM
Level 1 specification
3. There should be a way to control entites handling into passed values.
As a way to go i want to propose you to add one additional argument to
set_attribute(), set_content() and maybe some other functions - $options.
For now there will be 2 options:
XML_KEEP_ENTITIES - to treat all entities as entites and create them as
EntityReference DOM objects
XML_QUOTE_ENTITIES - to treat all entities as literals and hence quote all
special symbols in them (such as '&' char).
For compatibility reasons $options for set_attribute() may be set to
XML_QUOTE_ENTITIES as default value and $options for set_content() - for
XML_KEEP_ENTITIES.
Internally you probably should change xmlSetProp() call into
domxml_elem_set_attribute() to xmlNodeSetContentLen() when there is
$options=XML_KEEP_ENTITIES.
