Summary: CatalogManager can't resolve system ids

Initial Comment:
If you pass a system id, but no public id to  to resolve_sysid 
you get back None.

I believe the resolve_sysid function of xml/parsers/xmlproc/
catalog.py is 
missing a return statement on the  final line (the "pubid== 
None" case.)

Attached is a file catbug.py that demonstrates the problem 
and a patch named catalog.patch that resolves it.

PyXML + 4Suite compatibility

Newbie question:

I have 4Suite installed and am using the xml + xpath packages.

If I install PyXML, will 4suite still work ?

Will PyXML, specifically the xpath stuff work ?

PS: I don't want to use both at the same time. Just trying to evaluate 
which one to use.

Can anyone share some experiences about the difference ?

Thanks
   Torsten

Thanks. I did, but it doesn't really answer the question (for me)

The PyXML README says :
If you want to use PyXML's experimental XSLT package, you need to pass
--with-xslt to setup.py.  If you also want to install FourThought's
4Suite package, you should not install the XSLT package and also avoid
the XPath package, so you can use the one from 4Suite.  This can be
done by using the command line option --without-xpath.

That suggests some incompatibilities to me, but I don't know how or 
what.

Sorry, I cannot help with real experience. But on
http://uche.ogbuji.net/uche.ogbuji.net/tech/akara/nodes/2003-01-01/choosing-
software I found this:

Yes.  4Suite is designed to work with PyXML.  Infact you need 4Suite  
installed to perform validation.

The xpath implementation that ships with PyXML is out of date.  We will  
be resynching it shortly, but for now you will want to use Ft.Xml.XPath

They are both from the same code base.  xml.xpath was copied from  
4Suite over a year a go and I don't think anyone has had the time to  
update it since then.

Hope that helps

[ pyxml-Bugs-750437 ] can't create catalog entry for pathless system identifier

Summary: can't create catalog entry for pathless system identifier

Initial Comment:
When the a catalog is processed with the SYSTEM keyword 
to associcate a storage object identifier with a system 
identifier, both are converted into full filesystem paths 
based on a location of the catalog file, or any BASE entry 
found. 

This means that you can't create a catalog entry like:

SYSTEM html.dtd /usr/share/sgml/catalog/html.dtd

because the system identifier "html.dtd" will be converted 
to a full path, and then be missed in the search if
the DTD entry says:

 <!DOCTYPE html SYSTEM "html.dtd">

The way to handle this that fixes my case is to not turn the 
initial system identifier in the catalog command into a full 
path before storing it the catalog. If it is left relative and 
pathless, it will be found in the search. I can understand if 
this solution doesn't work for other situations.

Because XPath 2.0 and XSLT 2.0 are irredeemable crap.  I've made this argument 
in more detail so much recently that I'm tired of the whole discussion.  For a 
flavor, see [1] [2] .  As I can squeeze out time, I prefer to spend my time on 
working on a more sane set of alternatives [3].

There are a *lot* of folks, users and implementors who have also sworn to have 
nothing to do with W3C XPath 2.0 and XSLT 2.0.

[2] http://www.adtmag.com/article.asp?id=7620
[3] http://lists.fourthought.com/mailman/listinfo/xpath-ng

"I was among the earliest implementors of XPath and XSLT. I thought, and still 
think that they were remarkably well-conceived languages. XPath and XSLT 2.0 
are ruined by excess, and I'd be surprised if they supplant the 1.0 versions 
any time soon, as they are."
