python-dwca-reader in Jython about python-dwca-reader HOT 7 CLOSED

Oops, looks like lxml is the only parser BeautifulSoup can use

"Right now, the only supported XML parser is lxml. If you don’t have lxml installed, asking for an XML parser won’t give you one, and asking for “lxml” won’t work either."

So the new question becomes, "Would it be possible to have the reader not depend on BeautifulSoup?"

Hi John,

Indeed, you've perfectly nailed it: python-dwca-reader depends on BeautifulSoup, and BeautifulSoup needs lxml. I've myself been uncomfortable since a long time to have such an heavy dependency for relatively "peripheral" features.

So one of my medium-term plan was to replace BeautifulSoup by something lighter, or at least make it optional. Do you urgently need to use python-dwca-reader? I can in the next few days (let's say a week) find time to evaluate if I can publish a new version that doesn't depend on BeautifulSoup. If not too hard and useful for you, I'd definitely go for it. It's also a good opportunity to test it (and fix it if necessary) on Jython, I don't think it has been done before!

Best,

Nico

I am using python-dwca-reader actively, but the Jython context does not have the same urgency as just using the Readers. I thought about forking the repository and making a version that had BeautifulSoup optional, but it would probably take me longer than next week to get around to it. If you can do it that same time frame, that is better. I will gladly test it as soon as it is ready.

Cool, didn't know you were already using it, happy that my work is useful to others.

I had a quick look, and it seems indeed that it should be possible to make an version of python-dwca-reader that replace BeautifulSoup/lxml by ElementTree from the standard library... If I'm not mistaken, it is also available in Jython, and so we shouldn't be too far from having Jython compatibility... What do you think?

I think, "Excellent, go for it." Waiting anxiously.

Hi John,

I just released a new version (0.7.0) that totally drops the dependency to BeautifulSoup and lxml. All the APIs that were returning BeautifulSoup objects now return xml.etree.ElementTree.Element (from the standard library). Could you have a look?

I only checked very briefly, but it seems to work under Jython!

Confirmed that this works great under Jython and completely solves the issue for me. Closing. Thank you very much.
