I just checked and I cannot see that the organization publishing these data
files offer any XSLT stylesheet. IOW, I am, perhaps incorrectly, assuming that
the publisher of the data would be one with said stylesheet. (Although perhaps
that is something an end-user could put together as well??)
Although the data format of each data series is unique, it is simple and could
conceivably be parsed using grep but I am looking for a more "forward-looking"
solution for other applications in the future.
If XSLT stylesheets are not available - would you suggest another tool? Or,
would you suggest I design sheets, presumably one for for each data series?

[CentOS] XML parsing in shell script
I have a challenge I am interested in getting feedback on.
I will on a regular basis download a series of data files from the web where
the data is in XML-format. The format is known in advance but is different
between the various data files. I then plan to extract the various data items
("elements?") from each data file, do some light formatting and then save
desired parts of each original data file as a formatted CSV-file for later
importing into a database.
As the plan is to use a bash shell script using curl to get the files, I have
begun looking at external XML parsers that I can call from my script, perhaps
specify which elements I want, get the data back in some kind of bash data
structure and finally format and save as CSV-files.
There seems to be a number of XML parsers available but perhaps someone on the
list has a recommendation for which one might suit my needs best? I should add
that I am running CentOS 7.

In order to do a full install set, we need a certain set of packages. This set of packages is pretty much set in stone (you need all the deps to do every install in the comps set). I can not really adjust this package set unless we take some items off the installer. This means that the DVD is indeed too big for some media.

"How old hardware should be expected to work." Again this is not the core issue the original person was asking. Upstream (RHEL) usually expects hardware that is confirmed to work to be usable through the release time. This hardware is usually on the year of release to 4 years afterwards. So RHEL-7 was released in 2014, so tested hardware configurations from 2014-2018 should work. Outside of that there are some work to make it work but the rules from online docs seem to be that if the hardware was from before 2012 and not a tested configuration, it should stick to RHEL-6. [This is mostly about a level of support that would be given point of view.. sure you could get it to work on a 2004 computer.. but if it breaks support is not going to spend hours/days/weeks trying to make it work. Consulting services are for that..] CentOS has no support levels so if it works cool. if it doesn't then sorry. That goes for any dot release. If something is not caught in testing when various dot releases are being built.. that's too bad. [This isn't a new thing.. we didn't respin 5 releases when something wasn't caught until months later.] Also this is not really related to the original person's problem. It worked for them for many different releases and doesn't now. 2. "What are expected release results?" This is what the original question falls into. They have been running under the assumption that one set of DVD's would fall under a limit size for the single density drives. It has worked for multiple releases before 7.9 and then it didn't. However that expectation does not seem to have been in the testing procedures as a 'halt' level problem (i.e. measured in testing and then sent back if failed.) I will be honest on my part, I have only done a 'looks' good enough as I don't have single density DVD's to test if it worked or not. I use USB sticks and virtual machines. I am expecting the other testers to have done the same thing. 3. "What can be done". This is what the original question needs answered. This was not caught in the release of 7.9 and that was a while ago. There are not going to be any more dot releases for 7.. there is no planned 7.10 so this is the final set of DVD's until 2024. At this moment, I don't know if a respin will make the images small enough and what would have to be dropped to make it fit. Respinning 'official images' now will also cause problems for a lot of mirrors and users who will ask 'did these images get hacked? why did it change now?' [And in either case, the original person needed this fixed yesterday, not in the 2+ weeks to do this.] I am guessing someone could make an unofficial set of spins which cut out some packages to try and make it fit in single density. -- Stephen J Smoogen. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

To add to that: it would be unreasonable to expect from “binary replica” distribution to compose DVDs (or CDs) differently from upstream vendor. Therefore, media size may end up larger than limit.

All of this could be avoided with a simple external disk reader like this: https://www.amazon.com/Portable-External-Optical-Touch-Screen-Recorder/dp/B084WS3DHR/ref=sr_1_8?dchild=1&gclid=EAIaIQobChMIzNfR3PW57wIVkb3ACh0kqwzLEAAYASAAEgJQvPD_BwE&hvadid=177198149510&hvdev=c&hvlocphy=9019301&hvnetw=g&hvqmt=e&hvrand=1400606177523862771&hvtargid=kwd-10430955625&hydadcr=18062_9813221&keywords=external+dual-layer+dvd+burner&qid=1616073225&s=electronics&sr=1-8 On 3/18/2021 12:24 AM, John R.
