[XML-SIG] Problem with wddx marshaller

[Christian Scholz]

Hi!

I am trying to read some data from a server in wddx format. This actually
fails because it contains umlauts which IMHO shouldn't fail as long as
the encoding is set right. 
I tried the same with DOM and this parser reads it without problems.

Here is my failing test script:

-----------------------------------------------------------

from xml.marshal.wddx import loads
from xml.dom.minidom import parseString
from xml.dom.ext import PrettyPrint

s="""<?xml version="1.0" encoding="iso-8859-1" ?>
<wddxPacket version='1.0'>
 <header></header>
 <data>
    <struct>
        <var name='dummy'>
            <string>dummyname</string>
        </var>
        <var name='name'>
            <string>Gröhlkinder</string>
        </var>
    </struct>
  </data>
</wddxPacket>"""

print "testing dom"
doc=parseString(s)
PrettyPrint(doc)

print "testing wddx"
print loads(s)

-----------------------------------------------------------

So the first call is successful and it gets pretty printed and
the loads() call is failing with:

Traceback (most recent call last):
  File "./xmlbug.py", line 27, in ?
    print loads(s)
  File "/opt/Zope/python/213/lib/python2.1/site-packages/_xmlplus/marshal/wddx.py", line 272, in loads
    return WDDXUnmarshaller().loads(string)
  File "/opt/Zope/python/213/lib/python2.1/site-packages/_xmlplus/marshal/generic.py", line 321, in loads
    return m._load(file)
  File "/opt/Zope/python/213/lib/python2.1/site-packages/_xmlplus/marshal/generic.py", line 331, in _load
    p.parseFile(file)
  File "/opt/Zope/python/213/lib/python2.1/site-packages/_xmlplus/sax/drivers/drv_pyexpat.py", line 68, in parseFile
    if self.parser.Parse(buf, 0) != 1:
  File "/opt/Zope/python/213/lib/python2.1/site-packages/_xmlplus/sax/drivers/drv_pyexpat.py", line 49, in endElement
    self.doc_handler.endElement(name)
  File "/opt/Zope/python/213/lib/python2.1/site-packages/_xmlplus/marshal/generic.py", line 381, in endElement
    em(name)
  File "/opt/Zope/python/213/lib/python2.1/site-packages/_xmlplus/marshal/generic.py", line 409, in um_end_string
    ds[-1] = str(string.join(ds[-1], ""))
UnicodeError: ASCII encoding error: ordinal not in range(128)


So is this a (maybe known) bug or am I doing something wrong? 
(might fix it if I'd know where to start.. might look into this..)

FYI: PyXML 0.8.2 with Python 2.1.3 on linux is used.

regards,
  Christian
