Subject: [Expat-discuss] Can expat add "write xml file" support?
Message-ID: <4B4ADF15.1030100@gmail.com>

Dear all,
I'm trying to use expat for my xml file manipulation library. But I find
that it doesn't support writing to an XML file. I wonder if the
developer will have a plan to provide such an API. Thanks for your
delligent work.

Regards,
Kun

Very unlikely. Expat focuses on fast XML parsing, you'll have to look to other solutions for writing
XML, and there are many...

Really appreciate your reply.
I think that expat is one of the best API on AIX 6.10 platform. But now 
I'll try xerces first.

You can try SCEW (a simple expat wrapper) which allows writing to
files, memory buffers, etc. And the footprint is small as well.

Message-ID: <f9b51cc01001121437l60eadc64r4bef72582bf7e239@mail.gmail.com>

Hello,

Here is a quick question about parsing xml .gz file. Here is what I
did. With the following script

req = urllib2.Request(query_url)
xml_file = urllib2.urlopen(req).read()

I downloaded a compressed xml file.  The file has a suffix of ".gz".

Now I used

p = xml.parsers.expat.ParserCreate()
p.ParseFile(xml_file)

The last line gave

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: argument must have 'read' attribute

xml_file is not a file. It is a string therefore it gave an error.

Anybody knows how to uncompress the downloaded file? I know that
"gunzip" can be used to uncompress ".gz" files, however I do not know
how to get the uncompressed result.

Any help? Thanks so much.

I think you just want Parse instead of ParseFile since you've already
read the data into a buffer.

No, not directly.

An easy solution would be to pipe the xml.gz file through zcat.

You can do:

from StringIO import StringIO
from gzip import GzipFile
p.ParseFile(GzipFile(fileobj=StringIO(xml_file))

Hi,

Mozilla has made some real changes to expat. Would it make sense to
merge any of their modifications?  See the attached diff.

Best wishes,
Mike

I doubt it, we've been pretty good about upstreaming patches where it 
made sense. I don't think there are any left that would be of interest 
to others. Are you wondering about anything in particular?

Hi,

Python has made some minor improvements to expat. Would it make sense to
merge any of their changes? See the attached diff.

Note that a lot of the differences (i.e. using characters instead of
defines and losing support for large files) are because they have
version 2.0.0 of expat.  I'm not sure if any of the other changes would
be useful.

Best wishes,
Mike

I should have done a diff with 2.0.0 to begin with.  It turns out that
the only difference is that they include pyexpatns.h, which just
appends 'PyExpat_' to expat's symbols.

Sorry for the noise.
