SAXReaderNotAva ilble: No parsers found

Vincent Yau <y...@ohsu.eduw rites:
I am trying to use Python SAX API to parse XML files. I do see expat.py
somewhere underneath my Python 2.1.1 installation (on Solaris).
But I got this error when invoking the xml.sax.make_pa rser() call. Any
tip/help much appreciated.

You should install Expat before building Python. Best, you edit
Modules/Setup to build pyexpat explicitly.

Martin
Fast-forward to 2008

I installed Python 3.0b2 on a Windows Vista laptop (after having
previously installed Python 2.5), and I am getting this same error:

Traceback (most recent call last):
File "Programming\Py thon\monkeys.py ", line 24, in <module>
test_parse(sys. argv[1])
File "Programming\Py thon\monkeys.py ", line 21, in test_parse
xml.sax.parse(f , handler)
File "C:\Python30\li b\xml\sax\__ini t__.py", line 30, in parse
parser = make_parser()
File "C:\Python30\li b\xml\sax\__ini t__.py", line 90, in make_parser
raise SAXReaderNotAva ilable("No parsers found", None)
xml.sax._except ions.SAXReaderN otAvailable: No parsers found

I see a pyexpat.lib in the C:\Python30\lib s folder.
I also see a pyexpat.pyd in the C:\Python30\DLL s folder.

It works in Python 2.5. I installed Python 3.0b2 as admin.
Does anyone know what is wrong and how to fix it?

Does anyone have an answer for this?

I uninstalled both Python 2.5 and Python 3.0b2 and then re-installed
3.0b2, thinking that the installer was confusing 2.5 and 3.0b2 on
Windows Vista. Still have the same issue.
I had to use my XP machine, since the Vista installation seems broken
for Python 3.0b2. How do I fix this? How do I get Python to notice the
pyexpat.lib in the C:\Python30\DLL s folder in Vista?

Thanks

There seems to be no XML parser that can do validation in the Python Standard Libraries. And I am stuck with Python 2.1.1. until my web master upgrades (I use Python for CGI). I know pyXML has validating parsers, but I can not compile things on the (unix) webserver. And even if I could, the compiler I have access to would be different than what was used to compile python for CGI. I need to write a CGI script that does XML validation...

I'm working on a project where I have to create parsers on the fly, based on input to my program. I think Spark seems like a good candidate for the parser generation part, but it seems very geared toward hard-coded parsers. I could, I suppose, set the docstrings of the objects to contain the generated grammars, but that seems sort of like a misuse. Does anyone have any experience with "manually" constructing parsers with Spark, i.e....

I realize there are issues with the cached schema getting stale but I would like to know if any (many? most?) of the XML parsers out there cache a representation of the schema (or DTD) rather than retrieving and parsing it every time.

I know there are three most popular open-source XML parsers. They are expat, libxml, and Xerces. All three are cross-platform. Does anybody test these three parsers? Which one is the fastest when loading and parsing large XML files? Thanks.

A few days ago there was a discussion about which XML parser to use with Python. However, the discussion didn't cover validating parsers, at least, not w3.org XML Schemas. I looked into all the parsers that came up in the discussion but found no mention of w3.org schemas. It seems there are a few DTD validating parsers but that's all.

Greetings, welcome back at the sequel of the parsers article chapter. This part is dedicated to the ExpressionParser, the largest parser class for our little language. This class parses a complete expression and just like the other parser classes calls the Generator on the fly. When the parse has completed successfully, the generated code is returned. Otherwise the parse is aborted and an exception is thrown telling the reason of the...

Greetings, this week's article part discusses the parsers used for our little language. We will implement the parsers according to the grammar rules we defined in the second part of this article. As you will see shortly, the implementation of the parsers is an almost one-to-one translation of those grammar rules. Recursive descent parsing The grammar rules are highly recursive, i.e. one rule mentions another rule

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
