Okay, I have looked at what your code does. This should not be needed
in practice, or rather handled in a different way. I explain:
libxml already output such DOCTYPE informations, example:
~/XML -> cat test/wml.xml
<?xml version="1.0" ?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card id="card1" title="Rubriques 75008">
<p>
<a href="rubmenu.asp?CP=75008&RB=01">Cinéma</a><br/>
</p>
</card>
</wml>
~/XML -> ./xmllint test/wml.xml
<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card id="card1" title="Rubriques 75008">
<p>
<a href="rubmenu.asp?CP=75008&RB=01">Cinéma</a><br/>
</p>
</card>
</wml>
So when parsing a document with DOCTYPE informations, the existing
routines dump those correctly i.e. the problem is not with the saving
functions but your document structure.
I assume you actually build a document in memory, but parse the DtD
from the disk, and validate against it. The problem lies in the way
you prune the DtD in the document tree, just adding it as doc->extSubset
is not sufficient you should insert it as a node in the document child
list (before the root element but possibly after PIs or comments).
The following is the beginning of the dump of the wml document
as built in memory by the parser:
~/XML -> ./xmllint --debug test/wml.xml
DOCUMENT
version=1.0
standalone=true
DTD(wml), PUBLIC -//WAPFORUM//DTD WML 1.1//EN, SYSTEM http://www.wapforum.org/DTD/wml_1.1.xml
ELEMENT wml
TEXT
content=
ELEMENT card
[...]
Notice the DTD element, that's what missing when you build your
document, just create it and it should work without change to libxml.
Just call:
xmlDtdPtr xmlCreateIntSubset (xmlDocPtr doc,
const xmlChar *name,
const xmlChar *ExternalID,
const xmlChar *SystemID);
and it will create the missing node.
Should be simpler for you and for me :-)
