Subject: [XML-SIG] Python DTD parser?
Message-ID: <20100403134523.5655A19C71@theremin.major2nd.com>

Dear XML-SIG,

I am trying to find a working, maintained DTD parser written in Python.  The
main Python XML distribution does not include one.  I was using the PyXML
parser, but (1) (at least on SourceForge) it hasn't been maintained for
years, and (2) (as of the last version I could find, 0.8.4) it has a bug
that sometimes causes it to not process the very last line of a DTD -- which
in a well-modularized DTD is often an entity reference that pulls in the
main content of the DTD!

I've written my own DTD parser, but it omits some features, I really don't
know how well it conforms to the spec (which is important because I'm also
writing some DTDs of my own), and I'd much rather use a well-tested one
written by others.

Any advice will be appreciated.

		Sincerely,

						L Peter Deutsch

Nor anywhere else; the sourceforge site is "current", as it goes.

Are you attempting to only parse the DTD itself, or validate a
document according to the DTD?

If the former, xml.parsers.expat can be made to serve this purpose.

I'm not sure what people are using for DTD-based document validation
in Python these days.

Only the former.

Thanks very much.  I just now read the xml.parsers.expat documentation, and
I see the callbacks that correspond to the callbacks from the PyXML DTD
parser.  I think I was using the PyXML parser because that's what Stefan
Behnel's dtd2py used, which was the starting point for my current project;
but in any case, I see no reason to use it any longer.  Sorry to have taken
your time for this.

Dear XML-SIG,

I'm sorry to impose on you, but I've had a very frustrating afternoon trying
to report a couple of Python expat bugs on the PSF bug tracker.  SourceForge
appears to have lost all of my account data (for the second time), and when
I tried to register separately on the bug tracker site, the registration
process said "An unexpected error occurred during the processing of your
message" and failed to complete.

I'm using the Ubuntu Linux 8.04 distribution, which includes Python 2.5.2.
The libexpat1 version is 2.0.1-0ubuntu1.1 (hardy-updates), but I don't know
whether Python uses this or includes its own copy of expat.

The smaller problem -- but one that still led me to waste a fair bit of time
-- is that the SetParamEntityParsing method of xmlparser objects is simply
missing from the documentation of xml.parsers.expat.  Unfortunately, the
default is to not parse parameter entities, even when reading external DTDs,
so calling this method is required for DTDs that use parameter entities.  I
finally discovered this method by going to the expat Web site and look at
the C API.

I checked the Python doc for 2.6.5, and this method is still missing.

The larger problem is that often (but not always) when the Parse() method of
xmlparser returns after completely parsing a file, something happens at the
implementation level that results in a completely bogus Python error
"TypeError: An integer is required."  The error may occur a few Python
statements later, which suggests to me that it is a memory bookkeeping
problem of some kind, but I have no idea how to track it down.  However, it
is totally repeatable, and I can provide a very simple example (a 220-line
Python driver, most of which isn't executed, and a 7-line DTD) that triggers
the problem.

I checked the PSF bug tracker, and I thought that this might be the same bug
as # 6676, but my test case doesn't call ParseFile more than once on the
same parser instance.

I would really prefer not to upgrade to a later Python version, especially
not to 2.6 or later, but if this bug has been fixed, I'm willing to consider
it.

As soon as the registration issue gets cleared up, I'll report these issues
properly, but meanwhile, I was wondering if either of them (especially the
execution error, which has me stalled right now) rings a bell with anyone.

		Thanks -

						L Peter Deutsch

Hi,
      Does XBEL supports TAGS attribute?
I see that in the <bookmark> element , "TAG" does not exist as an attribute.

If it's not there, can we define our own custom attribute to support tags?

Thanks,
Rachel

Hello. I've only done a litte bit of parsing with minidom before but I'm
having trouble getting my values out of this xml. I need the latitude and
longitude values in bold. I've tried several things. I think that I am
getting into the location tag but maybe the getAttribute function is not
correct for this example?

I don't see anything 'bold' in your mail, but your example tells me what 
data you mean.

Here is some untested code using xml.etree.cElementTree:

     import xml.etree.cElementTree as ET
     tree = ET.parse("thefile.xml")
     for tag in tree.getiterator("location"):
         print tag.findtext("lat"), tag.findtext("lng")

Note that cElementTree is both faster and simpler than minidom.

Stefan

Thanks Stefan. I tried this but it's not getting into the for block for some
reason. 
I'll keep trying!

Maybe the document uses namespace declarations that you forgot to show us?

Now that I look at my file it does not look well formed. Do I have to use a
file? I tried to do

tree = ET.parse(xml_response)

but i got a file IO error...

I don't really know... Here's the whole story.

I am retrieving the xml by calling this link.

http://maps.google.com/maps/api/geocode/xml?address=50+Oakland+St,Wellesley,MA,02481&sensor=true



Here's the entire function:

addr = '50+Oakland+St,Wellesley,MA,02481'

def geocode_addr(addr):
    hostname =  'http://maps.google.com/maps/api/geocode/xml?'
    prefix = 'address='
    sensor = '&sensor=true'
    url = hostname + prefix + addr + sensor
    
    print url
    
    handler = urllib2.urlopen(url)
            
    xml_response = handler.read()    
    print xml_response
    #dom = minidom.parseString(xml_response)    
    handler.close()
    
    tree = ET.parse("GeocodeResponse.xml")
    print 'here'
    for tag in tree.getiterator("location"):
        print 'here1'
        print tag.findtext("lat")
        tag.findtext("lng")


*** I actually just pasted the xml from the shell where i printed
xml_response and saved it into an xml file in my folder called
GeocodeResponse.xml to test this... before going through the work of saving
the xml into a file. I got the "here" but not the "here1"

I'm attaching my actual file..

Sorry! I appreciate the help! this is the last piece of functionality i need
to get working for my programming assignment!

I prefer amara:

>>> from amara import bindery
>>> doc = bindery.parse("http://maps.google.com/maps/api/geocode/xml?address=50+Oakland+St,Wellesley,MA,02481&sensor=true")
>>> locations = doc.xml_select(u'//location')

...     print loc.lat, loc.lng
...

I'd have to concur with that recommendation.  Google is uninterested in
defining schema for their APIs, so you need to process the XML manually and
hope they don't change their interface.

BTW: The lat and lon components of the location are elements, not
attributes.  For minidom, use:
    lat = item.getElementsByTagName('lat')[0]
    lat.normalize()
    print lat.firstChild.data

Much easier when you can generate a proper binding from a schema, or use
something like Amara that does so without a schema.

And indeed, they do change their schemas without real concern backward
compatibility.  The sitemaps are in the middle of changing even now.

parse() is meant for parsing files. Use fromstring() to parse from a string.

This works for me:

   >>> import xml.etree.cElementTree as ET
   >>> tree = ET.parse('gmap.xml')
   >>> print [ (el.findtext('lat'), el.findtext('lng'))
   ...         for el in tree.getiterator('location') ]
   [('42.3118520', '-71.2632680')]

Thanks all for the help. This gives me alot of good options and I have a few
working.... I learned a lot!
