EntityParser does not accept whitespace at end of file

[Maarten ter Huurne]

The xml.parsers.xmlproc.xmlutils.EntityParser class has a method "skip_ws" which skips whitespace. However, if it encounters end-of-file, it will raise "OutOfDataException" instead of returning normally at the end of the file. As a result, the catalog files from the "w3c-dtd-xhtml" package, some of which have whitespace at the end, are not parseable.

Example program:

from xml.parsers.xmlproc import catalog
xhtmlCatalog = catalog.SAX_catalog(
        '/usr/share/xml/xhtml/schema/dtd/1.0/catalog',
        catalog.CatParserFactory()
        )

Output:

$ python readcatalog.py
ERROR: Construct started, but never completed at /usr/share/xml/xhtml/schema/dtd/1.0/catalog:19:28
TEXT: '
'

Note that you will only get this output after patching bug 131595, otherwise the parsing will abort before the end of the file.

Suggested solution:

Disable the following lines in the "skip_ws" method:
        if match.end() == self.datasize:
            raise OutOfDataException()
See "_xmlplus/parsers/xmlproc/xmlutils.py", line 451.

Version info: python-xml 0.8.4-6ubuntu4 on feisty.

Is this symptom still reproducible in 8.10 beta or later?

[Maarten ter Huurne (maarten-ter-huurne)]

I don't have 0.8.10 beta or later installed and I don't really want to install from source and risk messing up my system. The bug report contains a test case that triggers the problem; if you have 0.8.10 beta or later installed please run the test program to see if the problem still occurs or not.
